What are the Steps of Thermoforming Process

Mold Design and Production

Molds are key to the manufacturing process of thermoformed products. It needs to be made by hand or CNC machining, etc., taking into account the size and shape requirements of the product as well as the process flow.

According to user requirements or sample specifications, the first production of good plastic molds, general conditions, are the use of gypsum production of plastic molds, but there are also wood and metal carving products for the mold, plastic production molds with the lowest cost of gypsum molds, followed by plating of copper molds, the most expensive is the aluminum mold.

Gypsum molds made after the first to let it dry naturally or dry completely, and then according to the product surface convex and concave specifics, with 1-2 mm drilling flower does not affect the product packaging model of the low-concave drilling of many small holes, if it is a product such as boxes, but also have to be drilled around the edges of a number of small holes, so that the production of thermoforming, can be pumped out of the air, the mold drilled holes, but also have to be gypsum molds hardening, hardening treatment! The method is to soak the molds in a thick liquid solution of isotopes and then dry them.

Material Selection

According to the material requirements of the product, choose the appropriate plastic sheet material common plastic sheet material are PVC, PE, PET and so on. Before molding thermoforming, the plastic sheet needs to be cut and trimmed to match the mold.

Heating Plastic Sheets

Add the raw material into the thermoforming machine equipment for heating. Melting temperature and time according to different raw materials and product requirements, generally between 150 ° C and 200 ° C. When heated, the raw material gradually soften, transformed into a better plasticity condition.

Forming

The softened plastic is placed over the top of the mold and an air compressor is started to suck out the gas from the mold to rapidly forming plastic sheets. This step keeps the plastic tight against the mold surface for better molding.

Cooling

After the plastic softens and forms, the cooling and solidification process begins. This process requires uniform temperature and pressure on the plastic sheets surface and interior of the plastic to achieve the final effect.

Removing the Product

After the plastic has completely cooled, open the mold and remove the molded components.

Trimming and Polishing

Trim and shape the removed molded components, removing excess plastic and trimming the edges.

Quality Control

Check the appearance quality and size accuracy of the molded products to ensure they meet customer's requirements.

Thermoforming Machine Operation

The thermoforming machine is the core equipment for thermoforming production. During operation, the corresponding workpiece needs to be made according to the size and shape of the product, the material is placed into the upper mold of the thermoforming machine, and the lower mold is placed on the material. Then turn on the heating plate for heating, which is usually completed within 2-5 minutes. Pay attention to the temperature and time during the heating process to avoid overheating or overcooling. After the heating time is over, turn off the heating plate and suck into the lower mold to form the material.

(Inter)National Lego Day 

Construct creative builds with this beloved, versatile toy, enjoy the hilarious LEGO Movie or visit a LEGOLAND theme park with your family.

Lego – have you played with it? These little plastic colored bricks have been sparking creativity and joy in both children and adults of all ages for almost 70 years! Small but mighty, Lego bricks inspire creativity, and thanks to their ingenious design, they can be used to make virtually anything you can imagine, from cars to dinosaurs, houses to aliens – if you can dream it, it can probably be built out of Lego.

As such a versatile toy that appeals to all ages of people, it’s not surprising that Lego is now recognized as the World’s Most Powerful Brand, towering over Google, Nike, and Ferrari to claim the top spot in 2017, but as with most gigantic companies, Lego started from humble origins and International Lego Day marks the very beginning.

History of Lego

International Lego Day is held on the very same day that Danish carpenter, Godtfred Kirk Christiansen, first submitted his patent for the original Lego brick in 1958. Like no other brick that had come before this toy brick would have a sophisticated interlocking brick system, making it strong, versatile, and less likely to fall apart when simply knocked over.

Not one to mess around, Godtfred made sure not only to patent the design for his single Lego brick, but also to patent the concept of multiple bricks being used together in a building system, and this protected his design from being ripped off by competitors. Although this day is often seen as the birthplace of Lego as we know it, the company itself was in fact founded by Godtfred in 1932, creating a variety of wooden toys, and taking the name Lego from the Danish words “LEg GOdt” which translate to “play well”.

Ahead of their time, Lego was one of the very first toy manufacturing companies to buy an injection mold machine with which to create plastic toys, a move which shortly led them to create the very first plastic Lego brick in 1949. In the 17 years from 1949 to 1966, Lego grew exponentially into a global company that was retailing in 42 countries. They now boasted a product range that now contained 57 Lego sets and 25 Lego vehicles and with factories that were producing more than 706 million Lego elements each year – but the company didn’t stop growing.

In 1967 the LEGOLAND Band was established and in 1968, the very first LEGOLAND opened its doors to the public, attracting more than 625,000 visitors in its first season. Today there are 9 LEGOLANDS across Europe, Asia and the US, with a further three due to open in the next few years.

Nowadays Lego is a truly global enterprise, its strong brand identity, and still unique simplistic design, keeps it a favorite amongst children, while its history and versatility make it even more collectible to adults.

International Lego Day Timeline

1932 LEGO founder starts a woodworking shop in Denmark

In a small woodworking shop in Billund, Ole Kirk Christiansen makes all types of furniture and household items. But his favorite creations are toys for his sons, so he eventually names his company LEGO–a combination of two Danish words meaning “play well”.

1946-1949 Plastic bricks are first sold by the LEGO company

A wood shortage following WWII makes manufacturers look for alternative ways to create products. Christiansen gets his hands on the first plastic-injection molding machine in Denmark and starts selling the Automatic Binding Brick, the predecessor to today’s stackable blocks.

January 28, 1958 LEGO patent application is submitted

With Christainsen’s son, Godtfred, at the helm, the company submits their patent application for the tubes and studs that would add stability and connectivity to the plastic blocks. This anniversary coincides with International LEGO Day each year.

1976 LEGO minifigures are introduced

Realizing that the sets might be more fun if a human dimension was added, the company releases the iconic yellow-faced humanoid bricks.

2014 LEGO feature film is released

When watching his son play with LEGOs, a Hollywood producer gets the idea to make an animated movie. It is a huge hit and grosses more than $450 million, with more films coming in the following years.

10 super-fun facts about Lego

In 2016 LandRover set the World Record for the largest piece of Lego construction with their huge 43-foot-high replica of Tower Bridge. This monumental structure used 5,805,846 individual pieces of Lego which would have stretched all the way to Paris in France if laid out end to end.

If Lego Minifigures were to be classed as a population, they’d be the largest population in the world! With more than 4 billion of them in total.

There are so many Lego bricks in the world, that it’s estimated that they outnumber people 80 to 1.

Despite the first Lego brick having been made in 1958, you could still interlock one with a Lego brick-built today – the design hasn’t changed a bit!

In 2009, James May created a house entirely out of Lego! The house took more than 3.3 million bricks to make and even had a working toilet, a bed, and a shower!

Lego is now so popular that 7 sets are sold every second.

Although Lego is played by both girls and boys, women and men, they still have a bit of a way to go before they reach gender equality with roughly 86% of their Lego Minifigures being male.

If you were to collect all the Lego bricks in the world and stack them together then they would be 2,386,065 miles tall!

Although Lego makes toys they are also classed as the world’s biggest tire manufacturer, making over 400 million tires each year to keep their fleet of various lego vehicles rolling.

Although Lego was the first to patent the Lego brick that we know today, they didn’t technically invent them. The story has it that the salesman who came to sell Godtfred his first plastic injection mold machine was carrying an example interlocking brick in his pocket which had been designed and patented by Hilary Fisher Page. Godtfred improved on the design by perforating the brick and adding tubes on the bottom to help tighten the connection.

How to celebrate International Lego Day

Whether you’re five or sixty-five, you’re never too old to celebrate International Lego Day. Here are a few things that you could do to celebrate the day:

Play with Lego! Perhaps the most obvious thing to do on International Lego Day is to play with Lego of course! Grab your old lego set, or buy one especially for the day and sit down for a few hours of relaxing and creative fun. If you now have children yourself then make a sculpture together and take a moment to remember how many generations have grown up with Lego by their side.

Watch the Lego Movie! Lego has become so iconic that it even has its own movie dedicated to it. In fact, there are now two! Fun for all the family, cozy up on the sofa with some popcorn and watch as Lego figures come to life in stunning animation.

Visit LEGOLAND. And finally, for perhaps the most immersive Lego experience, pack your bags and take a trip to one of the many LEGOLAND theme parks. Be wowed by the impressive Lego structures and ride the exhilarating roller coasters for a day you’ll never forget.

Essential Facts About Injection Moulded Pallets

Injection Moulded Plastic Pallet manufacturing has advanced throughout time, with businesses working hard to utilize the latest technologies. The technique aims to optimize the parts, enhancing their thickness and structure, lowering their weight, boosting their longevity, and creating ever-more intricate patterns. Today, there are several methods for producing plastic pallets, making it often challenging to decide which way would improve our company’s supply chain��s efficiency the most. Injection, thermoforming, blowing, compression, and roto-molding are some of the most popular manufacturing methods we can find today.

The packaging company of pallets firmly believes that plastic pallet injection manufacturing ensures the quality of every one of our goods. Moreover, it adheres to our corporate core principles of sustainability and environmental care.

What are the main benefits of each available injection molding form?

One of the most common procedures for giving this material the desired form and size is the manufacture of plastic pallets using injection. For large-scale production, especially when maintaining stability and uniformity over time is necessary for the same pallet design, this method proves ideal.

Through a hopper, the plastic is fed into the machinery. The frictional force and heating bands melt the plastic. The heating chamber discharges the hot plastic through a nozzle into a cavity or mold, where a refrigeration system cools and solidifies it. The pallet will then assume the shape of the attached mold.

Various injection system types

Injection moulding plastic pallets use two different production procedures: low-pressure and high-pressure systems. Each of them has unique qualities and benefits.

1. Low-pressure apparatus

In this instance, the mold cavity receives the introduction of the plastic substance and inert gas. That is to say, a gas that doesn’t cause the importance to be introduced to react chemically. In this process, typically, carbon dioxide or nitrogen activates the blowing agents in the polypropylene/polyethylene combination through heating, creating a stiff plastic material enclosing a cellular core.

2. High-pressure injection molding

High-density polyethylene (HDPE) or polypropylene (PP) plastic pallets are frequently made using high-pressure injection technology. It is a very accurate method that leaves a high gloss surface and doesn’t need any additional treatment.

In this production process, the raw material is heated to 250 degrees Celsius within a barrel with a spinning screw. Once it reaches the desired temperature, the machine injects the plastic into a mold. Here, it holds it under pressure, cools it, and then expels it at the other end. Therefore, the high-pressure injection molding method is the best choice when you require a plastic pallet with outstanding features.

Tailored Plastic Pallet Production: Professional Guidance for Every Business Need

1. Raw Materials Preparation.

Start with the stock’s raw elements. The following often accept five hundred kilos or one tonne. The following is a combination known as a formula. Permit mixing of the same hue. Inject the plastic pellets into the mixture and incorporate the color from the formula bundle. Heat the mixture to prevent warping of the plastic pallets in each injection lot. Part 2 then appeared.

2. Mold Alteration

Once the mold has been made, the mold department must be contacted, or the mold must be changed. Turn on the injection molding device for plastic. CANE must be utilized to transfer the mold from the lifting or moving mold to the injection molding machine. The injection department’s role is to perform this. Mounting the mold to the injection machine for plastic pallets involves coupling the mold to the coolant pipe.Cold molded plastic creates an injection moulded plastic pallet.

3. Adjustment in Injection Moulded Plastic Pallet

The majority of them are chiefs in the injection department. This will change around the time of the injection. A robot will be adjusted to handle and remove plastic pallets from the mold, and the quantity of plastic pallets required to create a full plastic pallet will be modified to align with the injection cycle.

4. Plastic Injection for Pallets.

The injection process initially injects a substantial amount of plastic pallets. Because plastic is still in its early stages, plastic pallets are not ideal. Plastic injection molding is insufficient. Furthermore, the machinery employed in plastic injection molding must undergo tuning. Such as changing the injection time and heating the syringe. Slower to provide more time for the polymers to flow into the mold. Additionally, they will begin to minimize the injection time each time they inject 1–10 plastic pallets into a whole exercise, making the process quicker. To be able to provide additional injections each hour.

5. Pallet Cuts made of Plastic.

The quality control division determines which injection moulded plastic pallet require customization. This includes tasks such as removing any protruding fins and runners cleanly. Plastic pallets may also incorporate rubber and plastic sealing. Quality control checks are conducted on plastic pallets before they are delivered to the warehouse.

6. Quality Check of Plastic Pallets before Warehouse Delivery

Does the Quality Assurance Department have a quality checklist to ensure that the injected plastic pallets are good enough to turn clients away? We will identify the reject plastic pallets, which require mending, as soon as we assess the quality if the plastic pallets are not superior. However, clients can still deliver orders using plastic pallets that have previously received an injection for inspection—delivered to the warehouse in preparation for client delivery.

Conclusion

Injection systems with high and low pressures are crucial to producing plastic pallets. The industry opted for this method of production for its plastic pallets because, over the past several years, there has been a trend in the plastic injection industry towards equipment that is quieter, smaller, faster, and with a reduced environmental impact. Additionally, these advancements have led to more controlled hydraulic systems and energy consumption.

Dice making is an Interesting Process You Must Know About

Usually, plastic is used to make Gaming dice from plastic dice manufacturer. With liquid plastic, Steel dice molds are injected. Creating a small blemish on each die, the individual dice are clipped off once cooled. To smooth off the blemish, they are put into a rock tumbler. The dice are dipped into paint to get color into the numbers and then to get rid of the excess paint, it is tumbled again. To give them a nice luster, the dice are tumbled again.

The dice do not tumble evenly and end up slightly egg-shaped, which is the problem with this process; making them land on some numbers than others more likely. As they are more likely to roll truly random results, Precision dice are not tumbled. That’s why dice aren’t tumbled in the casino. Without ruining the sharp edges, the blemish left on a precision die can be sanded off easily.

The Carving and Casting Basics

Whether that’s the highest-end woods and metals as well as mass-market plastic, there are two main ways of making dice out of something:

The materials are made malleable and put in molds that are the inverse of the die design. It’s already shaped like the die when is removed from the mold after the material hardens. This is known as casting. For plastic dice from plastic dice company, Casting has usually used some metals, and novelty materials like chocolate, soap, and candy.

All the pieces that won’t be part of the final die are removed after a chunk of solid material is taken. This might be via carving, grinding, CNC milling, machine or laser engraving, or sandblasting. For some metal dice, stone and wood, these methods are used usually.

There are also some emerging and specialty methods, but for much of the dice market, they don’t account. You never know what you’ll see for sale in a few years’ time as Industrial technology improves rapidly!

Acrylic Dice Through an automated process, Acrylic dice are made by plastic dice manufacturer. It’s not safe or practical for hand-makers because of the temperatures involved. This means that making acrylic dice in bulk is easy, and almost all mass-market dice historically have been acrylic.
