Plastic Injection Molding and Customization

Custom plastic injection molding machines were created in early 1930’s to meet the growing industrial needs and complexities of the molding process. The machines used in such factories allow for mass production as well as repeated runs of particular parts.

During the plastic injection molding process, these machines are used to make custom plastic parts and have  become one of the easiest and most cost effective processes that is used by leading industries that use plastic components or parts. In this process, to manufacture custom plastic parts, melted plastic is injected in a mold using hydraulic force to give the plastic a particular shape. Around 35 percent of all plastic parts today are manufactured using custom plastic injection molding services.

Why the Plastic Injection Molding Process Works

Aside from being simple and reliable, it is also extremely efficient. One should have absolutely no doubt about using this process to manufacture custom plastic parts. A custom plastic injection molding machine consists of three vital components that usually vary from model and make.

The mold is the main component that gives the desired shape to the custom plastic parts, while main clamping unit holds various mold parts together throughout the process. The injection molding unit processes the plastic granules and feeds it directly to the mold for the final product. Custom plastic injection molding has definitely revolutionized the manufacturing sector, with more developments improving the efficiency in producing complex custom plastic parts. Here are some of the benefits of the process.

It's fast. This is the main reason why injection molding is one of the best technologies for long manufacturing runs. It’s really fast. How fast? While the manufacturing speed for custom plastic parts will depend upon the complexity of the mold, generally it is about 14-30 seconds pass between cycle times.

Plastic injection molding is accurate.  It's a highly precise process that can easily fabricate any kind of plastic part. There are some design restrictions but molds used in the machine allow the finished product to be very precise. Usually the accuracy is within 0.005 inches. Low labor costs is another reason for molding plastic.  Injection molding machines run with an automatic, self-gating tool that keeps operations streamlined and production process ongoing, requiring minimal supervision.
The final reason for injection molding is flexibility.  Aside from being highly accurate, the injection molding process used to manufacture custom plastic parts is also a highly flexible one. You just have to change the type of material which is being produced as well as the color of your product to get entirely different results.

So if you need plastic parts, the best process to get them made is plastic injection molding.

The Fives Stages Of Plastic Injection Molding (Contd.)

Plastic injection molding is one of the most widely used processes in manufacturing.  Since plastic is a material that, when heated to the proper temperature, becomes molten, that means it can be shaped into a wide range of parts.

Custom Plastic Parts:  The Final Steps of the Manufacturing Process

Stage 4: Ejection

After enough time has passed, the custom plastic part that has cooled may be removed from the mold through the ejection system, which is affixed to the back of the mold. When the mold has been opened, it is then pushed out by a mechanism. In order to eject the part, force must be applied--this is because the cooling process causes the part to shrink and adhere to the mold. A release agent may be sprayed on to the mold cavity surfaces before the material is actually injected, so as to make the ejection process easier. The dry cycle time of the machine can be used to estimate the time required to open the mold and eject the part; this estimate needs to include the time it took for the part to be pulled free from the mold. Once the part has been ejected, the mold may now be clamped shut for the next shot.

Stage 5: Post Processing

As with any other cycle, some post processing is usually required--a time used to take care of odds and ends. During the cooling phase, there will be solidified pieces left inside the mold. This excess material needs to be trimmed from the part;as we covered previously this can be achieved by using cutters. For certain types of material, like thermoplastics, scrap material that comes from this trimming may be recycled. The pieces are placed into a plastic grinder, also referred to as granulators or regrind machines, which will regrind the scrap into pellets. The integrity of the properties of these material may be compromised, so the regrind needs to be mixed with raw material in the proper ratio to be reused in the plastic injection molding process.

Injection Molding and Final Thoughts

Sometimes, only a handful of parts are needed.  Other times, hundreds or even thousands of parts are called for.  As a result, when you're looking for a company that does plastic injection molding in Chandler, make sure that you  find one that can not only make you the part to your specifications, but one that can make you the amount that you need.
