Plastic Injection molding PMMA

What is Material PMMA?

PMMA, or polymethyl methacrylate, is a polymer that is used for various applications. It can be machined or thermoformed into sheets. It is also commonly used in lighting fixtures and automobile lenses. This material exhibits a unique property that allows light to be reflected in its surfaces. It is also used to create optical fibres for endoscopy and telecommunication.

This versatile thermoplastic is typically used as a replacement for glass in the sign industry. It’s cost-effective, shatter-resistant, and lightweight. It can also be used as paneling in large stadiums and aquariums. Acrylic is also commonly used in layer fluidic manifolds, making it easier for operators to see where the fluid is traveling. PMMA polymers are also extensively used in medical applications, including dental applications.

Injection Molding Material Selection

The process of plastic material selection is an integral part of the product design process. By choosing the right material for your application, you can be confident that the product will meet your expectations for quality, cost, and performance. Furthermore, you will save time and money on manufacturing because you will not have to scrap any parts.

We can offer more than 100 different thermoplastic materials. If you are looking for alternative materials, please review our resin substitution guide for ABS, PC, PP，POM,PA,PBT,PPS and other common plastics, or contact us.

How Does Plastic Injection Molding Work?

Plastic injection molding is a process in which plastic pellets are formed and injected into molds to form the desired shape. The plastic melts in a chamber and reaches a specified temperature, so the injection time has to be calculated correctly. Once the desired shape is achieved, the plastic pellets are cooled, and the mold is opened. An ejection bar is then used to force the solid plastic part out of the open cavity.
