Injection molding production process parameters and precautions for polyamide (nylon) products

1. Process characteristics Polyamide (nylon) is a crystalline plastic with a high and obvious melting point, a narrow melting temperature range, but high melt fluidity; volume change of raw material before and after melting is large, melt has poor thermal stability and is easy to decompose; product shrinkage rate after injection molding is large, but it has good wear resistance, flexibility and…

What's your favorite 'Nikto has a crush on reader and must now do something about it' approach

The silent Nikto that stares at reader trying to manifest their affection? The stray cat Nikto that just walks into their life and refuses to leave? The socially inept Nikto who's afraid to approach so he injects himself in little ways; watching over them from afar while they're on a run or at a bar? The direct Nikto who straight up goes to reader and asks them out? The tsundere Nikto that becomes a little mean because he doesn't know how to handle his feelings? Or something else? (love me all versions)

-Kyumi

I love all versions of nikto but honestly rn I could use a nikto who forces himself into your life while you're sick. Like you're on base and you got a headache, a cough, and a runny nose. Resting in your room as directed by the medic and while you're under the covers you hear the door click open. Sure your first thought is that it's your colonel checking in on you but after hearing the first step the words die in your mouth.

Nikto who carefully untucks you out of your comfy covers, knowing and smelling the fact that you haven't showered well in over a week due to your sickness. Nikto who just came back and also needs one himself as he ungraciously undresses you while you weakly protest. Unable to even do much, dizzy yet recognizing that he's trying to take care of you.

An equally tired Nikto who dragged a plastic chair into your room along with him just so you could sit down while you shower. Making sure the water was far too warm for himself yet the perfect temperature for you. Washing your hair and all, debating tying you up when you protest that you don't need any help. Nikto who forces your arms down when you try swatting him away. Pressing a kiss to your forehead as he does, understanding that you're not in the right state of mind to even think.

Nikto who likes seeing the dazed out relaxed look on your face as the warmth melts you. Holding you close and gently picking you up just so he can sit down and place you on his lap while you feel some form of peace after your week-long headache.

"Better yes?", chuckling while he asks. A low laugh that rocks through your body in gentle vibration as he presses a kiss to your forehead, knowing you can't even resist.

Nikto who turns off the shower hours later when it starts to go cold. Using up a whole base's worth of warm water supply for the both of you. Sure he's basically scolding himself till his skins raw and red but the pain free look in your eyes is all he needs to breathe clearly through the suffocating moisture of the shower.

Nikto who brought extra towels just to unroll them flat on your bed, slowly drying you head to toe as he makes sure not to wake you up. A frown on his face when he realizes how warm you already were.

Nikto who obliges happily when your unconscious body reaches out to him. Your soft muscles and skin pulling him down into a chokehold as you mumble incoherently through your dreams. Nikto who tries hard not to moan at the feeling of the front of your body against his back.

Nikto, exhausted and stuck, placed in a chokehold of you, falls asleep. But not before he places a hand around your wrist, making sure that you don't escape when you wake up.

××××××××××××××××××××××x x××××××××××××××××××××××

Idk I like delusional nikto who tries to manifest the attraction too. Cause honestly it would work on me. Like those eyes. Me when. Yk? Oh also domestic kink Nikto. Idk...but he would.

𝐮𝐩𝐭𝐨𝐰𝐧 𝐠𝐢𝐫𝐥𝐬. a collection of lines from the 2003 movie Uptown Girls.

❛ Some fairy tales are true. ❜

❛ I’ve alerted the management company about this. ❜

❛ You did this to me on purpose. ❜

❛ You’re my best friend in the whole entire universe, how could you possibly think a thing like this? ❜

❛ There you are, sweetie. ❜

❛ You know, you can get botox injections for that forehead wrinkle. ❜

❛ Hey, you want to pick up bacterial meningitis or polio, you be my guest. ❜

❛ Listen, I didn’t mean to – uhh... ❜

❛ You always do this. When are you gonna grow up? ❜

❛ This is like a world gone mad. Like I’ve stepped through the looking-glass or something. ❜

❛ I need my shirt back. ❜

❛ This place is beyond its normal grotesque. It’s post-nuclear. ❜

❛ I can’t believe you did this to me after all the strings I pulled. ❜

❛ I know that I’m an undeserving creep, but can we please talk about it over lunch?❜

❛ Fine, see if I care! I’ll live off of water and sunshine. ❜

❛ I actually am uniquely qualified for this position, having spent so many years developing my skills as a people person.

❛ What is this, The Shining? ❜

❛ How cool is this? Look at this little tea set! Look at these cute little scones! ❜

❛ Hey - hey. You don't touch that unless I happen to invite you to tea. ❜

❛ Ugh! You just got your germy drool all over my plastic scone, you freako! ❜

❛ You missed a spot. ❜

❛ Why don't you get your little plastic baggie out and dig up some penicillin? ❜

❛ When you work for me, you leave when I say you can leave. ❜

❛ For your information, I do not work for you. I am employed by your mother. ❜

❛ Swinging door. ❜

❛ Baby, what are you doing outside all by yourself? ❜

❛ I know this is a big change for you, but it'll feel like home in no time at all. ❜

❛I can't believe those creeps would throw a destitute woman out onto the street.❜

❛ Chivalry is so dead. ❜

❛ You can't keep all this stuff. ❜

❛ You sure looked great out there. ❜

❛ I just... you know. Yelling at you the other day and all..? I'm sorry. ❜

❛ What are you doing here? ❜

❛ You're on probation. ❜

❛ Act your age, not your shoe size. ❜

❛ Don't you ever do that to me again. ❜

❛ You're hurting me. ❜

❛ You hurt me. Take it back. ❜

❛ I really hate surprises. ❜

❛ My glands are swollen. I'm having an allergic reaction. My immune system is crashing. ❜

❛ You know you had fun. ❜

❛ It must be hard getting rid of all this neat stuff, huh? ❜

❛ Can I have just five more minutes, please? ❜

❛ God, you're pathetic. ❜

❛ That's kinda harsh. ❜

❛ It's a harsh world. ❜

❛ Could you please help me? This is starting to hurt. ❜

❛ There is never, ever an excuse for hitting another person. ❜

❛ We need to talk. ❜

❛ Those are the four most hateful words in the English language. ❜

❛ Why are you buttering my plastic scone? ❜

❛ I invited you to afternoon tea. The least you could do is be polite. ❜

❛ Are you still moping over that disgusting guy? ❜

❛ Other people always let you down. Why don't you forget them and do something for yourself? ❜

❛ Maybe some of us aren't good at anything. ❜

❛ Every grownup is good at something. ❜

❛ What's so great about being a grownup, anyway? ❜

❛ You're scared. ❜

❛ If you refuse to have a nice time with me, I'm going to have fun by myself. ❜

❛ What is with this music, anyway? ❜

❛ You know, I thought that maybe - just maybe, you'd remember we had plans tonight. ❜

❛ If I never have a drop of tea again, it would be too soon. ❜

❛ Please, go without me. ❜

❛ Is that what you think of our friendship? ❜

❛ Thank you for taking me in like this. ❜

❛ Well, look at this. Perfect 98.6. Only twenty degrees above the temperature of the beautiful day awaiting us outside. ❜

❛ I'm not going anywhere. Especially with you. ❜

❛ We're going to sit in giant tea cups and spin round and round in circles until we puke. ❜

❛ I can't believe I let you talk me into this. ❜

❛ Haven't you ever been to an amusement park? Ever? ❜

❛ Why is it so dead around here? ❜

❛ Let's go home. ❜

❛ You're lucky that you were mad. See, when you're mad, you don't miss people. And if you stay mad, it's like you never knew them at all. ❜

❛ I wasn't mad, [Name]. I was confused. ❜

❛ You were right, [Name]. I am scared. But you're scared, too. You're as scared as I am. ❜

❛ That water's contaminated, you know. ❜

❛ If you don't get out of there, I'll call the police. ❜

❛ A hundred and one degrees. Sick as a dog. ❜

❛ You better hope you don't get radiation poisoning from that toxic pond scum. ❜

❛ Take two echinacea and a Benadryl for your sinuses. Call me if you need anything else.❜

❛ You're the doctor. ❜

❛ I can't think of what to say. ❜

❛ When I'm not ready, you hunt me down. When I try and make it work, you're not interested. ❜

❛ All you do is take, and I've got nothing for you right now, so... maybe it's a good time to start thinking about someone other than yourself.. ❜

❛ This is everything that he's left behind in the whole world. ❜

❛ Grownups never stay friends with kids. ❜

Infusion|| Emerie/Hemlock one-shot

Description: Emerie wants to learn more about torture methods and asks for a hands-on lesson.

This one-shot is not technically nsfw, but I will include a content warning for: + needles + IV + other medical references

I don't know if there's a term for "consensual torture", but it's pretty much that.

 Emerie didn’t know what to expect; she wondered if she had made a mistake asking for this, but she didn’t want to back out now. As far as she knew, the anticipation was part of the experience, and in any case, it was something different from the scheduled monotony of her day to day. Still, she couldn’t fight back the anxiety creeping up on her. She was visibly tense and shaking slightly, hardly a surprise, given her attire. Despite the room’s frigid temperature, all she had on was the sleeveless undershirt and shorts that typically served as her underwear. 

        The temperature of the room somewhat complicated the otherwise simple procedure of placing an intravenous line in her arm. It took a slow couple of minutes of Hemlock’s fingers attentively searching the soft underside of her arm for a decent vein before he finally found one he had confidence in. Emerie winced as his needle sank into her flesh, but she knew that minor sting was nothing compared to what was coming. She turned her head to watch him clamp the tube and move on to prepare the syringe, moving as though the whole process came to him as naturally as breathing. In a way, it felt reassuring to know that she was in experienced hands, but it also led her to wonder how many times he had done this. This exact thing, she thought, probably never.

When he set the large syringe down on a sterile tray beside the table she was laid out on, she let her gaze linger over it. The fluid inside had no color or viscosity that she could easily detect; for all she knew, it could have been anything.

        “Whenever you want it to stop…” He reminded her, pushing a plastic bulb into her open hand. Her fingers curled loosely around it and her thumb toyed with the cord it was attached to in an attempt to seem unbothered. Hemlock moved around her to secure the restraints around her limbs. As each was pulled tight, her grip on the bulb in her hand became more rigid. He paused beside her head and repeated what he’d told her before they had begun, “You don’t have to do this. If you back out now, I won’t think any less of you.”

        “It was my idea.” She answered evenly. It was an idea she wanted to see through, not only as an act of stubbornness, but as an educational experience. She had been given brief lessons on methods of enhanced interrogation, but had no first-hand experience with it. If it was something she may be expected to assist with, she reasoned, she should have some understanding of what it felt like. Stubbornness had only become a factor over time, after Hemlock had initially dismissed the idea. Now she had to do it. If he didn’t think less of her, she would think less of herself if she gave up now. She wanted to do it. It wasn’t for him, it was for her.

        He didn’t make any further attempt to dissuade her, simply secured the final restraint and moved on to make the injection. From the corner of her eye, she saw him deliver a few sharp snaps to the side of the syringe and saw a shimmering drop of liquid well up and spill out of the needle hub as he held it at the ready. She heard him unclamp the tube and briefly detected the flush of saline in her throat.

        “I’m going to go slow.” He told her as he fitted the syringe into the access port. Slowly, he depressed the plunger, sending half of the solution into her already tense body.

        Emerie didn’t have to wait long to feel the effect. It began as a stinging sensation at the infusion site. Before she had time to register the initial burn, it had shot up her arm and was overtaking her entire body, searing its way down towards her core. Her lips parted to gasp for air and the sound that escaped her was a strained cry of shock; she had somehow believed that the pain would come on gradually, not all at once like a bolt to the chest. She fought to regain her composure, if only she could breathe then maybe she could steady herself.  As she exhaled in a series of short, heaving breaths, she was acutely aware of the serum sizzling in her veins like battery acid.

        Amidst the blinding pain, she felt something warm press against her wrist and looked to see Hemlock checking her pulse, seemingly untroubled by her initial reaction. The contrast between the waves of pain traveling through her body and the soft, albeit impersonal, human touch was confusing in a way she couldn’t quite put her finger on. The confusion itself intrigued her and pushed her to keep going. Struggling to take in another breath, she did her best to flex her hand toward the half-filled syringe.

        “More…” She gasped out. Even through her strained and blurry vision, she spotted a smirk pulling at the corner of his lips as Hemlock turned back to the syringe and unclamped the tube once again. His gaze lifted to watch her intently as he, very slowly, depressed the plunger all the way.

        Although Emerie had believed that the second round would be easier, she was once again shocked by the white-hot pain that rocketed through her body. This time, she didn’t even try to disguise her reaction, groaning through gritted teeth and pulling against the restraints as her body tried to thrash and twist away from the unseen source of its distress. She tried to pull in another breath, but each of her lungs felt as though it was held in a vise. Her chest barely hitched with a shallow gasp, followed by another and another as she tried to drink in as much oxygen as her panicked body would allow. She began to feel lightheaded, even as thousands of electrified needles stabbed at her nerves, and she could feel something effervescing at the edges of her consciousness, something she couldn’t identify that sparked as intensely as the pain surrounding her.

        Her hands, still bound at her sides, flexed and gripped the edges of the table as she managed to pull in a deep, shaking breath. The plastic bulb rolled off the table and dangled limp from its cord as she exhaled in a breathy wail, weak enough to almost be a sigh. Hemlock took this as a signal that she’d had enough and detached the syringe, wiping the port clean before flushing it again.

        “It will be over soon,” He assured her, disposing of the empty syringe. “Give it a moment to clear your system. Talk to me when you’re able to.” 

        Gradually, Emerie felt the pain begin to subside; as it faded, it left behind it a pleasant feeling that she had only felt in passing a few times before. Not a feeling of pleasure, but the relief that comes with the sudden absence of pain. Breaths began to come more readily as her body relaxed, and she savored the ease with which she filled her lungs. Her momentary bliss was disrupted when she felt something warm roll down her neck.

        “Am I bleeding…” She muttered, her voice coming out hoarser than she had expected. Hemlock stepped closer and examined her, undoing the restraint that held her head down and turning her face from one side to the other.

        “Sweating.” He corrected her, this time doing a slightly better job at hiding his smirk, although she still spotted it. He set to work on releasing the rest of her restraints. Puzzled, she lifted her now free hand to her face and wiped the moisture away from her skin. It was indeed sweat.

        “But it’s freezing in here…” She pointed out, still staring at her hand. “Isn’t it…? ‘M shaking…”

        “I can see that. Here,” He returned to her side with a towel, which he used to lightly dab at her brow before handing it to her so he could take her arm and ease her off of the table and onto her wobbly legs. “I’d like to hear what your findings are.” 

        They were sitting side by side on her bunk. Emerie had a blanket wrapped around her and a cup of juice held in both hands. She was still shaking, but her voice had returned and now she was describing her experience with exuberant fascination. 

        “I thought if I could just keep pushing through, eventually it would get easier…more manageable, at least, but it never did, it just kept going on and on and on and-”

        “Careful.” Hemlock warned her gently, supporting her hands with his before she had a chance to spill her drink all over both of them.

        “-and on…Yes, thank you.” She smiled sheepishly and took a sip of the electrolyte drink. It tasted like artificial fruit with an underlying saltiness that would be immediately recognizable to anyone who had ever consumed potassium powder.  “How long was it, altogether?” 

        “From the first injection, nearly five minutes.”

        “Only five??” She nearly choked on the bright orange liquid and hurried to cover her mouth with the back of her hand. 

        “Nearly five.” He corrected her. “It’s still very impressive. And you didn’t even confess to anything, so I’d say you held up well. Or well enough for nearly five minutes’ worth. At a low dose.”

        “I don’t have anything worth confessing…” She said with a weak little laugh, dipping her head to hide the warm bloom of pink that crossed her cheeks as she said it. 

        “Not everyone does. Most will come up with something, though.” 

        “Well,” Emerie lifted her head and sat up straighter, taking on a more academic tone. “I’ll keep that in mind for next time.” Hemlock’s brow raised in what seemed to her to be genuine surprise.

        “‘Next time’? I think once is enough.”

        Emerie deflated a little bit; she was confident she could do better if she tried again. Of course, the experience itself had been excruciating, but she felt there was still so much she could learn, about the process and about herself, given enough time. Besides, the way she felt now, radiant and weightless, somehow sparkling in spite of her messy hair and threadbare blanket and the bruise developing in the crook of her left arm, made the pain worth it. 

        “But I’m sure I could hold on longer next time,” She insisted, clutching her cup tightly in both hands. “You could even increase the dosage or…I don’t know…what about gradually increasing levels of intensity? I think that could be interesting.”

        “It could be very interesting.” He agreed, slowly nodding along to her suggestions. “But not tested on you.” 

        “Why not on me? You test on yourself all the time.” She tried to look resolute, but with her blanket cloak and her cup of juice she ended up looking adorably pitiful. Hemlock exhaled an amused scoff and brushed a few limp auburn strands off of her forehead.

        “There are some things you shouldn’t get used to.” He told her, wrapping his arm around her shoulders and pulling her affectionately to his side. He pressed a kiss to her temple and mumbled. “We really should wash your hair, though.” She laughed and playfully kicked at him as he stood and offered his hands to help her up. Although the conversation was seemingly settled, she couldn’t resist one final retort as she leaned against his side on the way to the refresher.

        “Next time I’ll make it to six.”

ailesswhumptober day 21: drugged / ambulance ride / "this will make you feel better, okay?"

chapter 7 / 7 of you fall and you crawl and you break | not rated, chose not to warn

bruce screams as the needle pierces his skin. he screams as he watches his red blood go into the tubes, and screams as the doctor tells him to stop screaming, and he screams in his dreams after his papa slapped him to sleep.

there's something wrong with his blood, with him, that makes bruce always have to go to the doctor. at least that's what papa and the nurse say. mama says no, that bruce is perfectly healthy and a good boy, but they don't like listening to mama.

in his dreams, a voice speaks over his screams. it's not mean, yelling for him to stop, but it's not gentle, either. it's just somehow loud enough that bruce can hear its words even when his ears ring and he can't even hear himself anymore. it doesn't tell him anything bad, only confusing, saying things like bruce is its child and destined for things with big, scary-sounding names. it speaks of taking over bodies and destroying relationships, of something called an apocalypse and bringing hell to earth, of hollowing out bruce's soul and burying itself there. 

bruce wakes up screaming, and can't even stop when mama cries and asks him so, so nicely to please be quiet, or he'll make himself sick again, and no one wants to go back to the doctor, do they? 

"this will make you feel better, okay?" mama says, holding a bottle to his lips. 

he latches on to it, 'cause his throat is sore and bottles are nice, and sighs a little as he finally calms down. he hiccups a few times, causing some of the water to dribble down his neck and make his skin itchy, but he has no reason to cry about that. his skin is already itchy from the pajamas and blanket stuck to his body with sweat, but itchy is an outside feeling, and he's mostly okay with those. it's the inside feelings, of thin needles and wider pieces of cold metal checking his temperature, that really make bruce upset.

he closes his eyes as he drinks the cool water, letting it push down all the pictures in his head of the fiery below-place full of glowing green doors and bleeding red earth. he's almost done with the bottle, almost nice and sleepy, when a hand snatches it from his mouth. 

"what in the world do you think you're doing?" papa shouts the question, but it doesn't sound like he wants an answer. "for christ's sake, rebecca, he's not a baby. he doesn't need this."

bruce untangles himself from his blanket and slowly sits up. his head hurts, and even though he's not thirsty anymore, the slight weight of the bottle in his hands and against his tongue helped him settle down. maybe if he reaches a little bit, he can take the bottle back from papa's hand. 

"he turned two last week!"

"exactly!" papa throws the bottle against the wall, sending shards of plastic across the room along with shattering any hope of bruce ever getting it back.

bruce watches in quiet sadness as the rubber nipple bounces a couple times on the floor. it's still in one piece, but there's no way it's ever gonna be able to be part of a bottle again. he's little and stupid, but bruce is big enough and smart enough about the way that papa works - he's gonna turn the entire house upside down and inside out until every bit of bruce's baby things are collected into the trash. 

dejected, but not surprised, bruce slumps back down onto his sweaty sheets and curls up into a ball. papa keeps shouting at mama, but bruce doesn't have guardian to keep him back. he hasn't heard from goblin in a while, either, and glow's nice but can't do anything to help. bruce falls asleep, shivering in his crib, and returns to nightmares of the below-place and his body being torn apart.

hulk screams as the needles pierce his skin. he screams as he watches his green blood flow into a dozen vials, as other syringes inject him with cocktails of what he assumes to be antipsychotics and sedatives, based on previous 'tests.' he screams as the officer tells him to stop screaming, and snarls and bites at the officer instead, causing him to back off for a moment before returning with a cattle prod. 

hulk eyes it with curiosity and skepticism rather than fear. there's something wrong with his blood, with him, that always leads hulk back to an examination room full of people hell-bent on breaking him to figure out what that thing is. hulk and bruce have tried countless times to say that they're healthy and more or less fine as long as people leave them alone, but the officers and scientists and whoever else turns up for the spectacle don't like listening to them.

it's much more entertaining to ignore them rather than speak once it's clear they won't listen.

the officer with the cattle prod proceeds to poke hulk with it, in an attempt to elicit a response more than anything else, and hulk decides to just watch the scene play out. he's been here before and he'll be here again, and he's already figured out an escape plan, so he might as well see what's in store for him. 

staying quiet, it turns out, frightens the officer more than the screaming. hulk raises an eyebrow at some of the more inventive experimentations, rolls his eyes at others, and his silent judgment causes an air of unease to fill the room. 

he falls asleep at some point after the blood draws and electrocution, and wakes up to find his shins partially detached from his knees and a tray over his chest displaying his lungs and a couple of fingers. it's not painful - when will these fools learn that hulk can't be hurt? - but the lingering dreams plague him as the so-called surgeons continue their operation.

in his sleep, a voice reminiscent of brian's mingled with sterns', monotonously and maniacally detailing a plan for taking over the universe. it spoke with certainty, as if its scheme is inexorable, which almost made hulk laugh; there ain't anything in this universe that can compete with his sheer force of will. the voice called itself the one below all and spoke of using hulk to break the world, for no other reason than causing destruction for its own sake and tormenting bruce's soul in the process.

hulk attributes the nightmares to the drugs swimming through his veins. if there's even the slightest hint of truth to the one below all being anything other than an imaginary creature, then there's a chance he might be up against something with the potential to actually damage him, and he has no idea how to combat it. 

he can, however, hurt the med team before breaking out of their facility, and smiles as rips off his restraints and lets out a blood-curdling scream.

New approach for rapid process stabilization of plastics

Plastic materials are prone to degradation by atmospheric oxygen. These auto-oxidation reactions occur at ambient temperature but become especially relevant during melt processing. Adding antioxidants to the polymers results in a pronounced slowing-down of the oxidation processes. Only in this way, the production of plastic parts by injection molding, for example, is possible.

Developing new plastic grades is accompanied by lengthy experimental procedures to optimize the antioxidant content. For Fraunhofer Institute for Structural Durability and System Reliability, these online rheological investigations are a promising method for accelerating the development process.

Antioxidants

Organic matter, and therefore also plastics, degrade by auto-oxidation when in contact with air. This degradation is initiated by elevated temperature or light and propagates as a radical chain reaction that causes cleavage of the polymer chains. The latter are primarily attacked by the OH radical resulting in the formation of hydroperoxide moieties. These triggers follow-up reactions leading to regeneration of the OH-radical.

Working of Vacuum Casting and Its Multiple Uses

To make complicated components, a liquid substance is sucked into a silicone mold under vacuum. This method is known as vacuum casting. Rubber and plastic are examples of elastomers that are utilized as liquid materials in vacuum casting.

Since polyurethane resin, a kind of elastomer is employed as the casting medium, vacuum casting is also frequently referred to as polyurethane casting or urethane casting. When producing plastic components, vacuum casting is a more cost-effective method than injection molding because of its reduced manufacturing costs.

For batch manufacturing and other low-volume production tasks, vacuum casting is a great method of production. Vacuum casting is widely utilized in India's manufacturing of industrial electronics, FMCG, and consumer goods.

How do you work with vacuum casting?

Injection molding, in which cast material is poured into molds to create items, and vacuum casting services are very comparable processes. The kinds of molds used in injection molding and vacuum casting differ from one another.

Molds for injection molding might be formed of steel, aluminum, or other materials. Silicone molds are utilized in vacuum casting, nevertheless. This significantly lowers the mold-making cost because silicone is more affordable and has better durability.

Polyurethane is the most often utilized casting material in this procedure. The qualities of various polyurethanes vary, including good shock and temperature resistance, elasticity, flexibility, and structural stiffness. Thus, different polyurethanes may be employed depending on the kind of product being created.  

Vacuum casting uses

Making complicated and sophisticated goods may be accomplished more cost-effectively and efficiently with vacuum casting as opposed to the conventional injection molding method.

Due to its efficient production process, vacuum casting finds widespread application in the fabrication of commercial items. The following are a few industries that employ vacuum casting:

Manufacturing of consumer goods

Vacuum casting is a more effective method of producing consumer goods including combs, hair brushes, makeup packaging, sunglasses, pens, and other stationery.

Industry of Food and Beverages

Vacuum casting is used to create food and beverage containers, bottles, cans, mugs, and glasses. Due to the process's great efficiency and ability to produce goods quickly, vacuum casting is widely utilized in various industries where rapid manufacture is essential.

Advanced industry

Excellent heat and shock resistance is a feature of polyurethanes. Therefore, the recommended production procedure for creating electrical device housings is vacuum casting by Vacuum Casting Manufacturer using polyurethanes.

hypodermic needle dick is cool and all but I always think of his ovipositor as engineered with oil-based silicone and plastics and nerve wiring and this glowing blue fluid filling it. This very fleshy and visceral tube like one of those liquid aquarium squishy tubes but like hot and ribbed idk I feel like I’m doing a poor job of explaining it. I love metal and plating as much as the next robotfucker but I love it when my robots have guts more pliable than human guts and twice as sensitive. I don't write abt this usually I just have thoughts.

OOooooooo i like that!! that's a very neat design and really matches with the squishy bits you can see on Jin's body (which I constantly wonder about biting :3)

Now I'm imagining your design but with gamer lighting after Jin went to Kamigawa and got inspired.

I just have a surgery fetish and think oil injections/probes are extremely hot. (My own design is actually also super sensitive as it is a probe--attuned to pressure, temperature and moisture among other things)

I love Phyrexian biology it's so modular and fucked up /pos

if he could have it his way, it'd go like this : great, beloved, highly esteemed special grade sorcerer gojo satoru bested the best of the best, usurped the title. saved all of japan - no, the planet ! and when the smoke cleared and his all precious cute disciples came in with the cake and party poppers, the greatest gojo in all of recorded history had tragically vanished without a trace, leaving his devoted followers in tears and heartbreak . . . not to spit in the face of the merciful gift of reality, of course, not when he could still flex all his fingers and wiggle his feet in their fluffy socks, could still close his teeth on the delicate give of a plastic bendy straw and grind the grit of strawberry powder between his teeth. it just wasn't the ending anybody wanted, could feel it stiff in the air the first day the air in the room'd gone heavy with too many bodies shuffling in to still be respecting the protocols of visitation ( ever rebellious, his adorable students ) could hear it, strange and disconcerting in between unwanted formalities, had had to sigh and grin and slice through the air with one flippant hand, crowing ❝ aren't i just the same as maki - chan now ? ❞ and letting the ruckus crack an iciness he'd suddenly felt too fatigued to dismantle bare - handed.

it'd be better to see it that way, steer them away from equating the reality to their own selves and sink into a more comforting version of a slight adjustment     and sinking into his pillow, the lids of his eyes falling heavy and flicking open again and again, it was a sick sort of fortune that the one who'd probably closest understand was the one who'd build an entire exotic onigiri menu in the process of explaining. the way it was went like this : great, beloved, formerly highly esteemed special grade sorcerer gojo satoru gave his all. burnt it all up like twigs tossed into a firepit, bones for kindling, charred flesh and blood to keep everyone warm. clear blue skies in his eyes fogged in the passing of a nimbostratus, in cumulus clouds leaving him faded like water over - boiling to the bottom of a kettle. a body dipped dense into the center of this world was still worth its salt, though, nothing too hopelessly artificial about his straight face, his steepled fingers and mild manners, grasping the minute prickles that'd glide over the span of his skin, buzzing, the weight and temperature and delicate scent inspiring a smile even with his head still settled straight, even with eyes unmoving. unseeing. ❝ i'm more popular than ever, these days. seriously never stops being true     everybody loves a winner. ❞ the air of his tone's punched in like a needle - point. self injected. carefully dosed. @vartouhix

The injection molding process involves establishing the optimum settings that control 4 main variables which are:- plastic temperature, pressure, velocity, and cooling rate. Without these optimum values, injection molded components will differ from their intended geometry. To establish the optimum values, we must do various tests so that the final components don't have geometrical issues that would cause interlocking components to be too loose/tight. For example, we use thermal cameras to observe how the heat generated in joints affects expansion when rapidly moved back and forth. While this is not normal behavior of how a joint would be moved (unless your Smart Doll is doing a runner after stealing your credit card), we still need injection molded parts to accommodate such expansion. We perform stress tests (axial, torsional, bending, shear) on each component with force gauges. We also perform tests to see how much force is needed to pull apart assembled components. One of these photos shows how the spine and shoulder joints still hold together even with 340 Newtons (34.6704 Kilograms-Force) trying to pull them apart. Evolve uses washers for the main limb joints that help distribute load and minimize looseness. The screws are tightened using torque screwdrivers set to 40, 60, and 100 centinewtons (depending on the limb) to create a unified and consistent experience. The next 3 months will be dedicated to establishing the optimal injection molding variables through continued tests. During this time, we are also training the team on Evolve assembly - the most time-consuming aspect is ensuring a balance of grease used for the haptic feedback grid/gears and torque setting. I will make an introduction video to Evolve soon to set the usual expectations and soon after, some may make it out to the wild before the official release in early Q2. You may start seeing Evolve bodies assembled for test purposes in the Timeline section on the Smart Doll online store. #tokyo #smartdoll #anime #manga #3dprinting #japan (at Mirai Store Tokyo) https://www.instagram.com/p/Cl5epYuSqRm/?igshid=NGJjMDIxMWI=
