Look around you right now and chances are you will see not one, but several items created at least partially with plastic. Packaging, computers, cars, dishes, toys and much more are made using plastic. Of course, there are several different kinds of plastic and also quite a few methods of processing these plastics in order to make consumer products or packaging. Read on and you'll discover more about the world of processing plastic.
Injection molding is one of type of processing, and in this process plastic is heated and then injected into a mold. Injection molding also can be used to create products out of metal or glass, although the use of thermoplastic granules is the most common. Thermoplastic comes in many varieties, and in general, refers to a type of plastic that can be melted and molded and then returned to the original state when cooled. Injection molding is one way to process thermoplastics, and while the finished product generally is of a high quality, this method is quite expensive and many companies prefer to use thermoforming instead.
Thousands of items are created each day using a process known as thermoforming, and it has some similarities to injection molding. Instead of using granules of plastic, this is a procedure where plastic sheets are heated and then formed into a specific shape. A mold of the product or package is created, and then the heated plastic is fitted inside and the excess plastic is trimmed away. Thermoforming companies produce products for virtually every industry, including food companies, retail companies, electronics manufacturers, pharmaceutical companies and agricultural companies.
Depending on your needs, there are multiple ways to complete the process of thermoforming. Vacuum forming is an excellent and cost effective option for those who need larger parts, prototype parts and items that simply don't have a large amount of detail. The plastic sheets are heated and then vacuum pulls the pliable thermoplastic down into the mold where it is fitted, cooled and trimmed.
Sometimes vacuum forming isn't enough and you need to add pressure as well to move along the formation process. This is known as pressure forming, and it is an ideal process when you are making plastic products with a large amount of detail, such as a molded texture or perhaps raised or recessed type on your product. The addition of pressure along with the force of the vacuum really pushes that plastic down into the mold.
When looking for a company to produce your plastic products, look for one that can help you with all the details, providing a total solution that includes everything from development to production to quality control and much more. Keep in mind that the costs for production have many variables, including the amount of items that are being produced as well as the type of thermoplastic that is used during production.
