What Factors Affect The Properties of a Polymer?

What factors affect the properties of a polymer?

Polymers are a versatile class of materials with a wide range of applications. They’re often used in products that need to be strong but also lightweights, such as sports gear and vehicle parts. In this blog post, we will explore some factors that affect the properties of polymers. Understanding these factors allows you to better design polymers for specific applications and achieve the desired properties.

What is a polymer?

Polymers are materials that consist of many repeating units, or monomers. These monomers can be small molecules, like ethylene glycol, or large molecules, like styrene. Polymers can have many properties due to how the monomers are linked together. Some important factors that affect the properties of a polymer include: 1) The type of monomer: Different monomers will give polymers different properties. For example, ethylene glycol is a functional group molecule with two reactive groups on it (one at each end). This means it can join with other molecules easily to create long-chain reactions.

Styrene is a simple molecule with no functional groups, which means it's less likely to link up with other molecules and form long chains.  2) The degree of polymerization: The more monomers there are in a polymer, the more complex the structure will be and the harder it will be to break down into its individual monomers. Higher degrees of polymerization also make polymers stronger and more resistant to breaking down. 3) The type of bonds between the monomer molecules: Monomer molecules need to have specific types of bonds for them to link up together into polymers.

Several different types of bonds can occur between monomer molecules: covalent bonds (where two atoms share an electron), ionic bonds (where an atom gains or loses an electron), and hydrophobic (water-avoiding) bonds. 4) The degree of orientation: Polymers can be oriented in two main ways: random or crystalline. Crystalline polymers comprise long chains of identical molecules tightly packed together. This makes them strong and resistant to breaking down, making them difficult to process.

Random polymers are made up of shorter chains that are more spread out. They're less dense and more flexible, which makes them easier to process and shape.

Properties of Polymers

Polymers are a type of synthetic inorganic or organic compound. The molecules that makeup polymers are connected together through covalent bonds, which means that the individual molecules are permanently linked.

This makes polymers strong and flexible and resistant to heat, water, and many other elements. Polymers can also be formed into various shapes, including films and fibers. The properties of a polymer depend on several factors, including the size and shape of the molecules that make it up, the number of atoms in each molecule, and the way those atoms are linked together.

Some of these factors can be controlled by the polymer's chemist, while others are determined by the polymer's natural environment.

Factors that Affect Polymer Properties

The properties of a polymer are determined by the chemical composition and the manner in which the molecules are linked together. Some important factors that affect the properties of a polymer include: -The type of monomer used to make the polymer. -The degree of branching in the molecule. -The way in which the monomers are joined together. Each of these factors can have a significant impact on the way a polymer behaves, conducts electricity, and reacts with other substances.

For example, polyesters are made from carbon-carbon double bonds, while polyamides are composed of alternating nitrogen and carbon atoms.

Multiple bonds make polyesters strong and resistant to heat and sunlight, while polyamides tend to be more flexible and have better electrical properties. Another factor that can influence a polymer's properties is the manner in which the monomers are joined together. Polymers that are highly branched will tend to be less stiff than those that aren't as branched because they're able to move more freely through the material.

On the other hand, rigid polymers are often made from chain molecules that don't branch easily, so they exhibit high resistance to compression and don't stretch much when under stress.

Conclusion

Polymers are a type of molecule that consists of many repeat units. Polymers can be made from many substances, and their properties depend on the monomers that make them up.

Some factors that affect polymer properties include the composition of the monomers, the temperature at which they are mixed, and the amount of cross-linking that occurs. We can better control their behavior in various applications by understanding how these factors influence polymer properties.

What’s the Difference Between Thermoforming and Injection Molding

Often, customers in their own hands of the product in the thermoforming process or injection molding process can not tell the difference, or their own design in the end should be used in the injection molding process or thermoforming process?

In the market, the most common plastic parts in the market are thermoforming products or injection molded product. and thermoforming and injection molding are popular manufacturing processes. In fact, for many products, both can vacuum form and also can be plastic injection molding,. That specifically. In which way, do different users have different choices, exactly how is good? Cost, efficiency, and quality are often the most important considerations.

Of course, they are not opposites but complementary. In this blog, we will introduce the Difference Between Thermoforming and Injection Molding in detail.

Different Manufacturing Process

Thermoforming processing

The principle of thermoforming technology is also called the vacuum forming molding process. It is a thermoforming processing method, the use of the thermoplastic sheet, the manufacture of open plastic shell products the method, is the plastic sheet is cut to a certain size after heating and softening, with the help of the heated plastic sheet on both sides of the difference in air pressure and mechanical pressure, so that the deformation of a specific mold profile, after cooling and shaping, and cutting and trimming to complete the thermoforming products process!

Injection molding process

Injection molding is a process in which thermoplastic plastic pellets are heated and molten liquid polymers are, and then the molten plastic is injected into the injection molds through the injection molding machine with high pressure, after a certain cooling time, the plastic is solidified and shaped in the injection molding tooling.

Different materials used

The most significant difference between thermoforming and injection molding is the different materials used. The commonly used materials are PP, PE, ABS, PVC, PET, PS, and other thermoplastic pellets and sheets, while injection molding uses more thermosetting plastics, such as PP, PA, PC, ABS, POM, PE, and other granular raw materials.

Thermoforming uses plates and sheets, so the raw materials will be more expensive compared to injection molding granular materials.

Different design structure of products

Injection molded products are more accurate and can produce complex shapes and structures, while thermoforming products generally produce simpler shapes.

The shape obtained by injection molding is often the final product, and no further processing is required before it is installed or used as a final product. Many details, such as projections, ribs, and threads, can be molded in a single step in injection molding.

Thermoforming products can be produced in simple shapes, with smooth surfaces, are easy to process and assemble, and require post-processing to make holes and remove excess material after the product has been molded. The products mainly include packaging boxes, handicrafts, cards, and so on. Thermoforming products are also widely used in electronics, home appliances, medical and toys.

Different product usage

Due to the different materials and processes, there are some differences between the products made of thermoforming and injection molding. Thermoforming products usually have strong flexibility, impact resistance, and wear resistance, especially suitable for the production of curved and arched products, such as blister packaging boxes, three-dimensional billboards, and so on.

While injection molding products usually have the characteristics of high precision, high strength, good dimensional stability, etc., they are suitable for the production of electronic product shells, automobile parts, industrial equipment, and so on.

Different equipment and tools

Injection molding requires injection molding machines, molds, and other equipment and tools; injection molding machines are mainly divided into vertical injection molding machines, horizontal injection molding machines, two-colour injection molding machines, single-colour injection molding machines, high-speed injection molding machines and so on.

Thermoforming products require equipment and tools such as thermoforming machines and thermal processing devices. According to the different types of pressurization of thermoforming, the mainstream thermoforming equipment is mainly divided into the following three categories:

(1) Vacuum negative pressure forming machine, mainly through the negative pressure vacuum method, so that the plastic sheet is affixed to the mold;

(2) Positive pressure vacuum machine, through the air compressor on the front of the plastic sheet with atmospheric pressure, so that the softened plastic sheet is affixed to the mold;

(3) Positive and negative pressure vacuum molding machines, which form a strong pressure difference between the two sides of the plastic sheet by means of pressurization and vacuum, so that the softened plastic sheet is molded. These three kinds of equipment, each has its own advantages and disadvantages, need to be based on the characteristics of the product to choose the machine.

The parameters of temperature, pressure, and flow rate of injection molding equipment in the process of product processing can be precisely adjusted through the control system, which ensures the precision of product making. At the same time, injection molding equipment consumes less raw materials when processing high-precision products, which also reduces product costs.

In contrast, blister molding equipment is limited in the means of controlling parameters such as temperature, pressure, and flow rate, which is a limitation to the production of products requiring high precision.

Different production efficiency

Injection molding is a kind of high volume production runs plastic processing method. The general production efficiency of injection molding equipment can reach a production capacity of hundreds to thousands of pieces per hour.

At the same time, the degree of automation of injection molding equipment is also very high, and it can quickly complete the processing of products and improve production efficiency. In contrast, the production speed of thermoforming is slower compared to injection molding, and the processing time of the products usually takes several minutes to tens of minutes.

Different costs

A. Tooling Costs

Injection mold according to the complexity of the product, different precision, and mold material at different prices. The commonly used mold materials are S50C, P20, H13, 718H, NAK80, S136, etc., due to the complexity of the product is different, and involves a lot of complexity of the mold processing process than the thermoforming mold, the cost of the relative thermoforming molds are also higher than 5 to 10 times.

The molds used for thermoforming: The molds commonly used for blistering are gypsum molds, aluminum molds, copper molds, wood molds, and steel molds.

The materials used in plastic injection molds are relatively low, and the product structure is simple, so the molds are relatively simple, the materials are cheap, and there are lower tooling costs.

Gypsum mold: the material is gypsum powder, simple to manufacture and amend, usually a single piece of mold only needs 1~3 days, because it is brittle and difficult to dissipate heat, gypsum molds are usually used for the case of having samples handmade samples, not for production.

Aluminum mold: it is made of aluminum through machining and grinding. The aluminum mold has high precision, a smooth surface and is hard and durable, but the price is very expensive, generally used under strict requirements of the product, and ordinary molds can't achieve the precision effect of the use of such molds.

Copper mold: Copper mold should be made with plaster mold first, then take the sample to copper plating, and then fill with gypsum inside.

The copper mold has a better appearance and finish, strength can also reach the usual production requirements, and it is one of the widely used thermoforming molds.

Substitute wood mold: the material is substitute wood, the material cost is higher, needs CNC processing, the manufacturing cycle is short, usually a few hours, easy to sand and punch. The material is also brittle, suitable for sampling in the scene with 3D drawing files, not for production.

Steel mold: generally S45C, S50C, and P20 materials; generally thermoforming, use this type of steel mould.

B. Product costs

The cost of thermoforming vs injection molding is not the same. As the production process of injection molding is relatively simple, the cost advantage of injection molding is obvious when producing large quantities and high-cost products; while thermoforming molding is suitable for smaller production quantities, short production cycles, complex shape products, etc., which is relatively more economical.

The initial cost of injection molds is higher, but the cost per piece is lower when producing large quantities, and the start-up cost of thermoforming is lower, but the cost rises with the increase in production.

In injection molding equipment in the production process, recycling raw material loss will be much less than the vacuum forming molding equipment, especially in the production of larger batches of products, injection molding equipment in the cost savings have obvious advantages.

In addition, injection molding equipment has a higher degree of automation, which does not require much manual operation and also reduces production costs, it's more cost effective for high volume production.

Overall, injection molding is more efficient than blister molding is proven, although the investment in injection molding equipment is larger, in the long run, its production efficiency and production cost advantage will bring more profits and competitive advantage for enterprises.

Conclusion

To sum up, although both thermoforming and injection molding belong to the plastic molding process, there are obvious differences in their materials, production processes, uses, production precision, and product characteristics.

When choosing the molding process, you need to select the most suitable process according to the requirements and characteristics of the specific product. In the actual production and use need to choose the right type of product according to the specific needs.

tool and mark making workshop

in this workshop we made our own tools out of different materials we brought. I made three different ones that each gave me a different texture and pattern on the page. the first was a small scrap piece of a board wrapped with material, it was the most similar in look to a regular paintbrush. the second was a piece of thread that I weaved together, I used that to make circular marks by holding one side and dragging the other to make a pattern (similar process to using a compass). and the third was a pom-pom made out of plastic wrapping that I tied onto a long piece of wire (social distancing paintbrush).

me and my painting partner were very coordinated in the paintings we made together, we would start off by consulting each other and deciding on a vague vibe of what the painting should look like and then continuing to paint and just letting ourselves be creative with what were doing. we took a timelapse of each of the paintings we did (all posted above this post). for the last few paintings we tried to paint the white sheets of paper all black and then paint onto them using white paint to reverse the colour scheme. it worked really well but the pain soaked through the thin sheets and made them too heavy to stay up on the wall, we used this to our advantage and experimented further with the paint. we stripped the layers of paper and then turned them over paint side down and restuck them to the paintings underneath and used that as our new canvasses.

overall i really enjoyed this workshop, it taught me a lot and made me more comfortable with experimenting with my art, it was more about the journey and the experience of the workshop rather than the final outcome.

FIC: Kurt Birthday Drabbles

Earlier this week @elledelajoie left a comment on something I wrote all the way back in 2014.  I had genuinely forgotten I ever started it, but the original idea was to write 21 Kurt Hummel birthday drabbles. I had written just 7 of them, but after we chatted about it, I decided to go ahead and finish.  

If you’re not familiar, a drabble is a scene of exactly 100 words, not counting title headers. Since Chris Colfer and Kurt Hummel’s co-birthday (May 27) is coming up this Thursday, here they are. This goes definite AU at Birthday #19. Because you know I would never sentence my beloved Kurt to a life of being a doormat to people who did not appreciate and value him.

Never underestimate the power of feedback!

~*~*~*~*~

Birthday #1

Kurt’s blue eyes went wide as a frosted cupcake was set upon his high-chair tray, a single candle ablaze on its surface.  

When Mommy, Daddy, Uncle Andy, Grandpa Curtis and Grandma Eileen started singing to him, he smiled and clapped both hands hard around the tempting pile of frosting.

Kurt laughed when the sugary topping went flying and a big splatter of white abruptly decorated Daddy’s surprised face.

Everyone else started laughed too, including the startled father, who retaliated by giving his birthday boy a sticky peck on the cheek and then helped him to blow out a new candle.

Birthday #2

Kurt looked between his presents, confused.

Mommy had given him the pretty dolly he had begged for at the store. Daddy had given him a truck, not big enough to ride but too big to live with the little cars Daddy gave him at Christmas.

His parents seemed to be mad at each other.

Kurt looked at the doll, then at the truck. He smiled and placed Dolly inside the truck and began to drive her around the carpet.

Mommy and Daddy seemed surprised by his actions, but then they laughed, and Kurt knew he had figured out the puzzle.

 Birthday #3

His shoes were black and shiny, buckles on the sides and 1-inch heels on the base. He clomped over the hardwood floors, listening to the click-tap-click-tap in delight. They went perfectly with his dove gray coveralls with “Kurt” sewn on the pocket in black sequins. Mommy had made the outfit for him.

Spotting Daddy watching him, Kurt threw himself into waiting arms. Daddy’s smile looked like he had an owie but was trying to be a big boy and not cry.

Kurt hugged him. “It’s okay, Daddy.”

Burt looked surprised but hugged him back. “Yeah, buddy. I think it is.”

 Birthday #4

Ballet girls were nice. When they heard it was his birthday today, they threw him a party. Kurt puffed up with pleasure when presented with cookies, a sparkly wand and a tiara that read ‘Happy Birthday’ in shiny letters. He was not as fond of the kisses they gave, but four was very grown up, so he screwed up his face and allowed it. The teacher even let him wear the special puffy pink tutu over his little black leotard! 

 He saw Mommy and Daddy up in the gallery taking pictures, so he waved.

Kurt hoped today would last forever.

  Birthday #5

“Can I have cupcakes?”

Kurt’s mother looked up from her book. “I don’t think we have any, sweetheart.”

“Can we have some Thursday?  My birthday is the last day of preschool.”

“It is?” she said, looking surprised. “Is it your birthday already?”

He nodded seriously. “Don’t you remember, Mommy? You were there.”

She laughed. “Well, you have me there.  What kind of cupcakes would you like, sweetie? And don’t say cheesecake. Those are two completely different kinds of dessert.”

Kurt’s hopeful expression fell. “Oh,” he said, clearly disappointed. Then his face brightened again. “Chocolate?”

She nodded. “That we can do.”

   Birthday #6

“Daddy!”

Burt sat up just in time to catch the little body that launched at him. “What’s wrong, slugger?”

“It’s my birthday!”

Grinning despite the way his heart was hammering at the abrupt awakening, Burt asked, “Yeah? I like birthdays. Do I get a present?”

“No,” the boy scoffed. “I get presents!”

 Burt squinted at the clock. 3:15am. “Not until morning, you don’t.”

Kurt pouted and tried, “It’s almost morning.”

“Not close enough, kid. C’mere,” Burt pulled him into the warm bed between himself and his wife.

Kurt snuggled down and went right back to sleep.  

Burt was less lucky.

 Birthday #7

Kids had started treating him funny this year. He was too fancy, too girly, holding hands was weird.

Nobody was coming.

“I’m sorry, sweetie.”

“Am I too late?”

They jumped as a little black girl with pom-pom hair popped out of nowhere.

“I’m Mercedes,” she greeted. “We just moved here. Mom said you would have invited me if you’d known.”

“I’m Kurt.” He smiled. “Do you like tea parties?”

“Is there cake?”

Mrs. Hummel beamed. “Cake, ice cream, and Kool-Aid.”

Kurt shrugged. “Nobody else came.”

She grabbed his hand like she’d known him forever. “More for us!  Happy Birthday, Kurt.”

 Birthday #8

Kurt took a deep breath, thought for a moment, and carefully blew out the candles. All but the extra one that his parents always put on his cake.

“Aren’t you gonna finish, bud?”

He looked from Daddy over to his mother, home again, but so frail he was sometimes afraid to hug her, worried she might pop like a fragile soap bubble. He offered her the candle. “Here, Mommy. Blow it out. Maybe you’ll get another year to grow on.”

The eyes of the two adults met, then Mommy nodded. The three of them blew out the final candle together.

 Birthday #9

Barely daring to hope, Kurt came down the stairs.  Birthday cakes and presents had been Mommy’s specialty.  Daddy had forgotten his own birthday and had nearly forgotten Christmas.

Kurt gasped when he saw it, waiting, shining and spectacular against the front door.

“A bike!”

Bright green, sissy bars with foil streamers, and a banana seat. Perfect!

Burt smiled. He had scoffed a such a “girly” bike when Kurt spotted it at the toy store. But now, looking at the all-too-rare joy in his son’s eyes and feeling the approving smile his wife would have given, he nodded. It was perfect.

 Birthday #10

Buying gifts was tough when your kid always clammed up on you. A dad had to be observant.

Ten years old. A landmark like that needed something special, but the only thing Kurt seemed into was clothes. He had enough of those for ten kids.  

He’d probably like a Barbie he could change in and out of different outfits, but Burt cringed at the thought.

He did doodle pretty good though. Sure, it was mostly pictures of clothes, but that was a start.

A fancy sketchpad with a case and a hundred different colored pencils. Yeah, that was the ticket.

 Birthday #11

“Dad, where are we going?”

“You’ll see.”

Kurt sighed with exaggerated impatience. He had come home from school to find Dad waiting at the truck, ordering him to get in, then not saying another word. The suspense was killing him.

“Ta-Dahhhh!”

They had pulled up in front of a nondescript brick building. “Columbus Culinary Arts?”

“You like to cook right?  Well, we’re gonna fix your birthday dinner this year with the help of a real chef. Lessons are once a week for the next couple months.”

Gourmet cooking lessons!

“Oh wow. Dad, this is amazing!”

Burt grinned. “Happy Birthday, kid.”

 Birthday #12

Last year’s surprise had gone so well that Burt had decided on a repeat. But when he saw the excitement on Kurt’s face at finding a pair of tickets inside his birthday card turn to disappointment and horror, quickly masked with a fake smile, he knew he’d goofed.

“I know baseball isn’t your thing,” he said, almost pleading. “But you’ve never seen a live game before. It’s a whole different experience. It’s a home game. We can yell and scream, and cheer our team on with thousands of other fans.”

The stiff not-smile never wavered. “Sounds . . . fun.”

 Birthday #13

Dad had bought out one of the partners at the garage this spring and now owned a majority share of the renamed “Hummel Tires & Lube”. Kurt wanted to snicker at that name, but he was proud too.

His birthday this year coincided with Friday Night Dinner. Dad had invited all the mechanics over for a potluck. They’d had Mary’s special fried chicken, Cassius’s homemade cornbread, and Davy’s mac’n’cheese. Now Dad brought out the cake.

Kurt laughed. A sheet-cake with a tow-truck and two little plastic mechanics for decoration.

“You and me kid. Partners.”

The mechanics cheered and everybody dug in.

  Birthday #14

Kurt froze when he saw tickets peeping out of his card. Not again. Noise, sunburn, unhealthy food, tacky uniforms, and Dad trying so hard to make a boring sport seem like fun.

He sighed and pasted on a smile, which quickly transformed into shock.

“Wicked?” he squeaked, staring hard at the little papers as if the printing might change if he dared to look away.

“Embassy Theater is giving regional business owners a discount this year,” Burt said apologetically. “It’s just a traveling production, not real Broadway, but I …”

His apology was cut off by a joyful teenaged hug.

 Birthday #15

“Don’t worry, son, you got this.  Just remember everything I taught you.  You got a whole year to get ready for the practical test.”

“I know.”

“And it’s okay if you don’t get it right the first time. Not everybody does.”

“I’m fine, Dad.”

“I’ll be right here waiting for you when you’re through.”

“I know that, Dad. I’ll be okay, really.”

At that moment, Kurt’s name was called and he sprang from his hard green plastic chair. His dad’s repeated reassurances were making him jumpy.

Twenty minutes later, a brightly grinning Kurt was waving his freshly minted driver’s permit.

 Birthday #16

Burt patted the giant blue bow the dealership had provided over the hood of the shining black Lincoln Navigator.  

Kurt was gonna flip! He’d passed his DMV test with flying colors and was no doubt showing off his shiny new license to all his friends at school.  

He paused. Did Kurt have any friends to share this accomplishment with? He always seemed so alone.

Maybe that’s why he had decided to spoil his son with a huge birthday gift.

It wasn’t right for such a good kid to be all alone. Maybe having his own ride would help change that.

  Birthday #17

A dozen teens gathered in Kurt’s basement to celebrate the end-of-school, non-disbanding of Glee, and Kurt’s birthday, all in one.

“Not like ten years ago,” Mercedes said to Kurt, as they watched Mike and Brittany dance.

“Ten years?”

“Your seventh? It was just you, me, your mom, and lots of chocolate cake.”

Kurt was astounded. “That was you?”

“You forgot?”

“I remember a little girl who showed up and invited herself to my party.”

“And I remember a little boy who needed a friend as much as I did.”

He squeezed her hand. “Thanks for coming.”

She squeezed back. “Always.”

 Birthday #18

Kurt stared at his birthday cake, unable to think of anything to wish for.

He was 18-years-old today, a legal adult. He had new family in Carole and Finn, his dad was on the mend, he would be back at McKinley for senior year, he had made his first visit to New York City, and he had a boyfriend! One who had just told Kurt that he loved him for the very first time.

‘I wish for next year to be as good as this,” he thought, taking a deep breath and blowing.

The flames flickered out, all except one.

 Birthday #19

Senior year had been a disaster, and now he had not gotten into NYADA, despite his well-praised audition.

“Blaine wants me to spend another year here,” he whispered. “I just can’t.”

Burt’s callused hand squeezed his neck. “Then don’t. You’re 19 now, a man. You got talents galore, work experience from the garage, enough drive for ten kids, and your mom’s life insurance money to give you a start.”

“But…”

“No buts,” Burt said firmly. “You go on to New York and grab life by the balls.”

Kurt felt his optimism rise. “Help me look for apartments?”

“You got it.”

 Birthday #20

What a difference a year made.

He’d dumped Blaine after being cheated on less than a month after leaving Lima.  He was enrolled at FIT and sharing a shoebox apartment with a fellow design student and a Broadway hopeful, but both were young gay men from small towns, and they had a lot in common.

“Happy Birthday!” Elliott shouted, tossing a handful of glittery sequins at him.

Adam came in playing the birthday song on a kazoo he had gotten from who-knows-where. “Ready for Callbacks? $20 on who gets the first hot guy’s number!”

“I already have yours. I win!”

 Birthday #21

“I have the honor of presenting your first official grown-up drink,” Adam said, smiling lovingly at his grinning boyfriend of nearly a year. He set down a martini glass with a cherry floating on top. “A Manhattan seemed appropriate.”

Kurt beamed and gave him a kiss, then took an experimental sip. “I’ve had alcohol before,” he admitted. “Mostly wine, though.  Mm, this is good!”

“I thought you’d like it. Happy Birthday, my love.  May the future bring every good thing you wish for, and never more heartache than you can handle.”

Kurt could not have asked for a better sentiment.

Beautiful moodboard made by the amazing @peterquillzsblog Thank you again 💙

This was written for the lovely @youbloodymadgenius 400 Followers Writing Challenge. I'm super late, but thank you so much for letting me participate 💙 I had fun writing this and I hope you like it.

I used prompts #12 and #28. They are highlighted in bold.

...

“I told you not to fall in love with me.”

The words hit her like a fucking truck. They tumbled so easily from his lips with that dreaded nonchalant tone she'd only ever heard him use on others whenever he spoke over the phone. It was never aimed at her.

He had his arms crossed over his naked chest with brows raised, sitting comfortably up against the large fancy black headboard of his equally large and fancy bed, the very bed he had her in only nights before. His long hair was messy, shooting out in all directions from being tugged at mercilessly. A pretty blonde had snaked her way from under his black satin sheets, her naked body in full view. She makes a show for him, pulling her denim jeans over her sad excuse of a behind slowly, obviously interested in hearing the rest of their exchange.

Ivar licks his lips, his blue eyes following the soft lines of that broads basic body before shifting them back to her. “You’d only get hurt in the end.” He finally says.

What a low blow.

She swallows the lump forming in her throat, knowing the tears would be forcing their way out of her glossy eyes soon. How fucking stupid was she? She stood there, hands balled into fists as her eyes flipped between him and the smirking blonde. Her lower lip trembled like a goddamn child, standing awkwardly in front of the pair. From the looks of it, this dalliance with the blonde had been going on for a while. The girl seemed far too comfortable.

Ivar was right. He did warn her not to fall in love with him. It was just supposed to be a fling, nothing more. They had met at a mutuals party, Ubbe’s friends cousin or some shit. They couldn’t remember the details now if you asked them, but they both knew the guy, and when they met, it was instant physical attraction. And that was when their “friends with benefits” relationship began. She had been a phenomenal plaything for him, and she seemed to know exactly what Ivar needed. She was pretty, had an amazing body, shiny hair, long fluttering lashes. She looked perfect on his arm and he liked her enough to keep her around, but he didn’t love her. How could he? He wasn’t meant for that shit. He was Ivar the heartbreaker, a hot young bachelor born into the old money of the Ragnarsson family. He could have any woman he wanted. And he did.

She was so fucking stupid, but Ivar was fucking stupid too. He’d given her a key to his flat, allowing her freedom to come and go as she pleased as if they were a fucking couple. And she was stupid enough to believe that was the relationship they were forming, that somehow they had silently crossed this bridge of uncertainty that went from nothing to something. They had been “together” for months, almost an entire year. Ivar wasn’t a bad person, he was just bad at relationships. He couldn’t settle with one girl, so he played with many. She wondered how many others he played with when she wasn’t around.

Not much regret could be detected in his eyes, his blue orbs shimmering with the words she could read so clearly: Get out. So that's exactly what she did. Turning swiftly on her booted heels, she walks back into his fancy kitchen, slamming his key with this cute pastel blue pom pom keychain she bought onto the marble island counter. Digging into one of the totes full of groceries that she intended to use to cook the fucker dinner, she pulls out a small tub of Häagen-Daz strawberry ice cream, shoving it in her bag. She'd need it later. With a shaky breath she looks around the modern sleek flat one last time before slamming the door behind her.

She could hear that bitch giggling as she left.

…

“Did you see the look on her face?” Freydis giggles, slipping on her low cut cropped top before pouncing onto the bed beside Ivar, “Poor thing. You really had her hung up.” Ivar did see the look on her face, and although he’d seen it many times before on countless other women, it hit him a little differently this time. Dammit.

She looked heartbroken, eyes wet like that day her cat had gotten sick and she begged Ivar to rush them over to the vet that was an hour away. He didn’t really care much for the cat, it had sharp claws and was always hissing at him, but he did it for her. Her cat was saved from whatever the fuck was wrong with him, and she was happy. She’d given him the sweetest smile he’d ever seen.

That night had been a great fuck.

Ivar releases a breath from his nostrils, ignoring Freydis babbling on and on about god knows what. The blonde was a fool if she thought she would be next to take her place. Fucking bimbo. Was only good for a measly fuck. And she was terrible at it. He pushes away the satin sheets, completely nude, before turning to peer at her from over his sculpted shoulder with a look of indifference.

“Get out.”

“Ivar?” She looks up at him through her lashes, her lips forming into a frown at his sudden disdain.

“I didn’t stutter,” He states calmly, but a stern tone laced his words that had her sitting up at attention,” I said get the fuck out.” Freydis rolls her eyes, pushing herself off the bed and grabbing her purse she meticulously hung in his closet.

“Douchebag,” She mutters, but she offers him a sickly sweet smile, pushing a lock of her blonde hair behind her ear, “You know I’m always available. I’ll be waiting for your call.” She winks at him, blowing him a kiss before slinking out of his room. Once Ivar heard his front door slam close he sighs, shuffling over to his bathroom for a much needed bath.

For some reason, he felt dirty.

…

It had started raining as soon as she left Ivar’s flat. She had forgotten her umbrella at home and she was soaked to the bone from the heavy droplets by the time she stepped foot into her own flat.

It was cute and cozy, with fairy lights and tapestries that were the complete opposite of Ivar’s stupid modern sleek bachelor pad. Ivar preferred simplistic Scandinavian living, while she gravitated towards that boho atmospheric vibe with scented candles that she had in practically every room. He joked about it whenever he slept over, which wasn’t very often. It looked childish to him. The scented candles made him sneeze and the cat was a bitch, but he’d settle under her warm quilted covers just fine, gazing up at her ceiling that reflected a projection of a star lit sky. That was actually kinda cute. She was always a romantic, but that was the problem.

She kicks off her tall boots, tossing her keys atop the little ceramic dish by the door. Moving over to her tiny kitchen, she puts away the ice cream in the freezer and makes a b-line towards her bedroom. She hangs up her bag on the very corner of the door to her closet, shedding her jacket and the rest of her clothes on the floor without a care before heading to her bathroom. She immediately lights all her candles, setting up a relaxing bubble bath with a lavender scented bath bomb. Lastly, she grabs her phone, searching for the right playlist before sinking into the warmth of the bubbly water.

As soon as her eyes fall shut, her mind goes back to Ivar.

Fuck him. And the blonde.

She didn’t want to berate herself anymore than she already did while taking that miserable walk home, but she couldn’t help feel like her heart was burning a hole right through her chest. It beat faster the more she thought of him, and her eyes pricked with the sensation of tears, until finally, she let them fall. The fat drops roll down her cheeks as she cries into her hands to muffle her sobbing.

This would be the only night she’d shed tears for him, she promised herself. Tomorrow was a new day.

Benji, her fat calico cat, slinks his way into the bathroom, curling up in a corner to enjoy the warmth of the bath for himself. She brings her teary eyes to him, the calm state of the feline having her wish she could feel such peace. Sometimes she wished she were a cat herself, only having to worry about sleeping, eating, shitting, and doing it all over again day after day.

Sinking deeper into the water she forces herself to relax, listening to the soothing sounds of Moonlight Sonata, a dreary tune for a dreary day off. When her eyes fluttered with sleep, the classical playlist was interrupted by the obnoxious sound of her phone's vibration over the plastic toilet seat. With a scowl she reaches over to snatch her phone, biting her lip as Ivar’s name flashed on the bright screen. Without hesitation, she taps her finger to end the call, sending him straight to voicemail. She had nothing to say to him.

Fuck him.

After 30 seconds, her phone vibrated again. Ivar was fucking persistent.

Again, she ignored the call, and after the 4th call, she angrily slams her finger on the green button, bringing the phone to her ear.

“What do you want?” She spits, shivering now that the water had significantly dropped in temperature. She runs a hand down her gooseflesh covered leg as she awaits his answer, but so far he was silent, only a frustrated breath could be heard on his end, “I detect guilt.” Her words were dripping in pure venom, something he honestly found rather attractive. But now was not the time for that.

“Are you okay?” He asks softly, so unlike him, and somehow, so fucking irritating.

“Peachy,” She replies sarcastically, sinking into the water once again. The bubbles had long disappeared and she was getting cold, “Why do you care?”

“I don’t.” Was the weak scoff. There was an awkward silence after that, which was strange considering she felt she could talk to Ivar endlessly about anything really. That’s the sort of pair they were, or maybe it was her doing all the talking and soul baring while Ivar patiently listened and...kept his own secrets. She sighs, just about ready to hang up until she hears him mutter something.

“I can’t hear you.” She counters, annoyed.

“I didn’t want you to see this,” He clears his throat, “I didn’t want you to see us. Me and Freydis.”

“You did a great fucking job hiding it.”

“Is this really a good time for your sarcasm?”

“Fuck you, Ivar.”

“I’m being serious,” He hisses in frustration, “That was nothing for you to see. I had no idea you were off today.” He sounded irritated, as if it were somehow her fault he got caught. It shouldn’t have mattered if they weren’t anything to begin with. “I don’t even know why I’m explaining myself to you!” He ended his little childish rant with a sigh, the kind of sigh where he needed to run a hand down his face to keep his shit together.

“So then why the fuck did you call me?” She hissed back, and in her annoyance she splashed water from out the tub, the cold droplets sprinkling over Benji. It had the cat screeching for his life before running out of there.

“I don’t even fucking know myself.” She hears him take in another frustrated breath, grumbling something about the complications of women. Asshole. He was the complicated one.

The splashing of water was heard on his end. He must have been having a bath of his own. That was their thing, after a particularly rough day at work, or whenever the actions of their lovemaking called for a bath, they didn’t hesitate to slip in together and enjoy each other again. It was clear she valued those moments more than he did. It all meant nothing to him.

Her traitorous mind conjured up images of how his body must have looked, water droplets running down his glistening chest and chestnut colored hair plastered on his face. Fuck.

“I’m fucking stupid.” She groans, already feeling another wave of tears surging through her. She sniffles, bringing her knees to her naked chest as she stares at the flickering candles surrounding the tub.

“You’re crying,” Ivar says stupidly, his tone unreadable, “Please, don’t cry. I hate it when you cry,” He was speaking gently, as if that would be enough to soothe her, “I told you not to fall in love with me.” He repeats the phrase softly, almost sadly, like the corny lead of some fucking corny romantic comedy that did trash in the cinema.

“Yeah…” She says, fighting to hold back the sob she wanted so badly to release, “Yeah, I know.” And with that, she hung up, tossing her phone aside and sinking deeper into the now freezing water.

Maybe if she stayed in there long enough she’d feel numb.

…

She had stared at her ceiling, the star lit sky projection twinkling down at her, much like they always did when she was a little girl back in her hometown. They always did serve to calm her, making her feel safe and helped her sleep a lot better. They didn't help much this time around.

She stared all night, even after the stars disappeared with the sunrise, thinking about him. She was getting too old for this, crying like a fucking teenage girl.

She barely slept and was desperate for a cup of coffee the moment she rolled out of her cocoon-like bed. Dragging her feet over to the kitchen, she brews a pot of the caffeinated liquid before preparing Benji’s breakfast. The cat slithered between her legs, meowing uncontrollably as he awaited his food.

“Shut up, Benji.” She mutters to him tiredly, placing down his food bowl and giving him a quick pat. She leans against the counter, her eyes following the slow drip of the coffee into the glass pot, wondering how the fuck she’d gotten to this point. Her eyes hurt, swollen from all the crying she did last night, and everything felt hazy and slow.

After last night’s conversation with Ivar, she decided to block him, erasing whatever memories she had of him. Ivar was always a generous man with her, sometimes buying her little things that caught her eye, probably just things to appease her with she realized. She gathered all the items up in a cardboard box she had laying around, leaving it by the door to throw away once she left for work.

Finally, the coffee was done. She poured herself a much needed cup, adding a few drops of her favorite vanilla creamer. Taking a small sip of the hot beverage, she groans in delight as it coats her taste buds, ignoring the burning caused by her impatience.The fusion of bitter and sweet was helping her recharge for the day. She’d need at least 2 more cups if she was going to do these guided tours at the museum today.

There was a knock on her door as soon as she moved to get ready. In her confusion she pauses her morning playlist, turning to look toward her door as if something were about to burst through and devour her whole. It was 7:30 in the morning, an unusual hour to knock on anyone’s door. Her first thought was Ivar, but why would he even bother showing up to her door? He was never awake this early as he got to show up to his office whenever he wanted. Ruling him out, she finally makes her way to the door, peeking through the peephole. No one was there.

She unlocks the door, turning to look towards the left and right of the hall before looking down. She blinks, stunned.

Flowers. A huge bouquet of flowers. Her favorites actually, Gerbera Daisies, all in a soft powdery pink color with bright yellow centers. They were placed in a monstrosity of a vase of white porcelain, painted with stunning blue designs like fine china. Beside it was a small bag with a generic looking orange tabby cat on the front with its paw up. Those were Benji’s favorite treats.

Taking one last look around the hallway she bends down, carefully picking up the vase of flowers and the cat treats, all while pushing Benji back in before he tried to make a run for it. She tosses the treats aside, staring long and hard at the pretty flowers with a scowl. There was a white card clipped within the stems, wet from the vase water. Snatching it, she runs her finger over the parchment-like surface before opening it to see a familiar scrawl in the blackest ink. The water spreads the ink, staining the white card in black streaks like tears. She read the simple message:

I know these are your favorites. You deserve pretty flowers. I’m sorry you felt the need to fall in love.

-Ivar.

Her brows arch and a frown tugs at her lips. She felt her heart drop instantly as her brain finally processed the simple words he’d written. Reading it was enough for her to sense the emptiness of the message. She knew him well enough to know he slept just fine last night. Probably next to that other chick. How could he possibly think that flowers would make it all better?

She quickly rips the card into little pieces, tossing them into her trash can. She lifts the bouquet of daisies from their stems, removing them from the vase and throwing them harshly into the trash with a snarl. She squeezes her eyes shut, the tears already coating her lashes, rolling down her cheeks and onto those stupid flowers. She already broke her promise of no more tears and it wasn’t even 8 am. She bites her lips, glaring down at the daisies as if they were the root of the problem.

“Fuck you, Ivar.”

What’s the Difference Between Thermoforming and Injection Molding

Often, customers in their own hands of the product in the thermoforming process or injection molding process can not tell the difference, or their own design in the end should be used in the injection molding process or thermoforming process?

In the market, the most common plastic parts in the market are thermoforming products or injection molded product. and thermoforming and injection molding are popular manufacturing processes. In fact, for many products, both can vacuum form and also can be plastic injection molding,. That specifically. In which way, do different users have different choices, exactly how is good? Cost, efficiency, and quality are often the most important considerations.

Of course, they are not opposites but complementary. In this blog, we will introduce the Difference Between Thermoforming and Injection Molding in detail.

Different Manufacturing Process

Thermoforming processing

The principle of thermoforming technology is also called the vacuum forming molding process. It is a thermoforming processing method, the use of the thermoplastic sheet, the manufacture of open plastic shell products the method, is the plastic sheet is cut to a certain size after heating and softening, with the help of the heated plastic sheet on both sides of the difference in air pressure and mechanical pressure, so that the deformation of a specific mold profile, after cooling and shaping, and cutting and trimming to complete the thermoforming products process!

Injection molding process

Injection molding is a process in which thermoplastic plastic pellets are heated and molten liquid polymers are, and then the molten plastic is injected into the injection molds through the injection molding machine with high pressure, after a certain cooling time, the plastic is solidified and shaped in the injection molding tooling.

Different materials used

The most significant difference between thermoforming and injection molding is the different materials used. The commonly used materials are PP, PE, ABS, PVC, PET, PS, and other thermoplastic pellets and sheets, while injection molding uses more thermosetting plastics, such as PP, PA, PC, ABS, POM, PE, and other granular raw materials.

Thermoforming uses plates and sheets, so the raw materials will be more expensive compared to injection molding granular materials.

Different design structure of products

Injection molded products are more accurate and can produce complex shapes and structures, while thermoforming products generally produce simpler shapes.

The shape obtained by injection molding is often the final product, and no further processing is required before it is installed or used as a final product. Many details, such as projections, ribs, and threads, can be molded in a single step in injection molding.

Thermoforming products can be produced in simple shapes, with smooth surfaces, are easy to process and assemble, and require post-processing to make holes and remove excess material after the product has been molded. The products mainly include packaging boxes, handicrafts, cards, and so on. Thermoforming products are also widely used in electronics, home appliances, medical and toys.

Different product usage

Due to the different materials and processes, there are some differences between the products made of thermoforming and injection molding. Thermoforming products usually have strong flexibility, impact resistance, and wear resistance, especially suitable for the production of curved and arched products, such as blister packaging boxes, three-dimensional billboards, and so on.

While injection molding products usually have the characteristics of high precision, high strength, good dimensional stability, etc., they are suitable for the production of electronic product shells, automobile parts, industrial equipment, and so on.

Different equipment and tools

Injection molding requires injection molding machines, molds, and other equipment and tools; injection molding machines are mainly divided into vertical injection molding machines, horizontal injection molding machines, two-colour injection molding machines, single-colour injection molding machines, high-speed injection molding machines and so on.

Thermoforming products require equipment and tools such as thermoforming machines and thermal processing devices. According to the different types of pressurization of thermoforming, the mainstream thermoforming equipment is mainly divided into the following three categories:

(1) Vacuum negative pressure forming machine, mainly through the negative pressure vacuum method, so that the plastic sheet is affixed to the mold;

(2) Positive pressure vacuum machine, through the air compressor on the front of the plastic sheet with atmospheric pressure, so that the softened plastic sheet is affixed to the mold;

(3) Positive and negative pressure vacuum molding machines, which form a strong pressure difference between the two sides of the plastic sheet by means of pressurization and vacuum, so that the softened plastic sheet is molded. These three kinds of equipment, each has its own advantages and disadvantages, need to be based on the characteristics of the product to choose the machine.

The parameters of temperature, pressure, and flow rate of injection molding equipment in the process of product processing can be precisely adjusted through the control system, which ensures the precision of product making. At the same time, injection molding equipment consumes less raw materials when processing high-precision products, which also reduces product costs.

In contrast, blister molding equipment is limited in the means of controlling parameters such as temperature, pressure, and flow rate, which is a limitation to the production of products requiring high precision.

Different production efficiency

Injection molding is a kind of high volume production runs plastic processing method. The general production efficiency of injection molding equipment can reach a production capacity of hundreds to thousands of pieces per hour.

At the same time, the degree of automation of injection molding equipment is also very high, and it can quickly complete the processing of products and improve production efficiency. In contrast, the production speed of thermoforming is slower compared to injection molding, and the processing time of the products usually takes several minutes to tens of minutes.

Different costs

A. Tooling Costs

Injection mold according to the complexity of the product, different precision, and mold material at different prices. The commonly used mold materials are S50C, P20, H13, 718H, NAK80, S136, etc., due to the complexity of the product is different, and involves a lot of complexity of the mold processing process than the thermoforming mold, the cost of the relative thermoforming molds are also higher than 5 to 10 times.

The molds used for thermoforming: The molds commonly used for blistering are gypsum molds, aluminum molds, copper molds, wood molds, and steel molds.

The materials used in plastic injection molds are relatively low, and the product structure is simple, so the molds are relatively simple, the materials are cheap, and there are lower tooling costs.

Gypsum mold: the material is gypsum powder, simple to manufacture and amend, usually a single piece of mold only needs 1~3 days, because it is brittle and difficult to dissipate heat, gypsum molds are usually used for the case of having samples handmade samples, not for production.

Aluminum mold: it is made of aluminum through machining and grinding. The aluminum mold has high precision, a smooth surface and is hard and durable, but the price is very expensive, generally used under strict requirements of the product, and ordinary molds can't achieve the precision effect of the use of such molds.

Copper mold: Copper mold should be made with plaster mold first, then take the sample to copper plating, and then fill with gypsum inside.

The copper mold has a better appearance and finish, strength can also reach the usual production requirements, and it is one of the widely used thermoforming molds.

Substitute wood mold: the material is substitute wood, the material cost is higher, needs CNC processing, the manufacturing cycle is short, usually a few hours, easy to sand and punch. The material is also brittle, suitable for sampling in the scene with 3D drawing files, not for production.

Steel mold: generally S45C, S50C, and P20 materials; generally thermoforming, use this type of steel mould.

B. Product costs

The cost of thermoforming vs injection molding is not the same. As the production process of injection molding is relatively simple, the cost advantage of injection molding is obvious when producing large quantities and high-cost products; while thermoforming molding is suitable for smaller production quantities, short production cycles, complex shape products, etc., which is relatively more economical.

The initial cost of injection molds is higher, but the cost per piece is lower when producing large quantities, and the start-up cost of thermoforming is lower, but the cost rises with the increase in production.

In injection molding equipment in the production process, recycling raw material loss will be much less than the vacuum forming molding equipment, especially in the production of larger batches of products, injection molding equipment in the cost savings have obvious advantages.

In addition, injection molding equipment has a higher degree of automation, which does not require much manual operation and also reduces production costs, it's more cost effective for high volume production.

Overall, injection molding is more efficient than blister molding is proven, although the investment in injection molding equipment is larger, in the long run, its production efficiency and production cost advantage will bring more profits and competitive advantage for enterprises.

Conclusion

To sum up, although both thermoforming and injection molding belong to the plastic molding process, there are obvious differences in their materials, production processes, uses, production precision, and product characteristics.

When choosing the molding process, you need to select the most suitable process according to the requirements and characteristics of the specific product. In the actual production and use need to choose the right type of product according to the specific needs.
