What Is Thermoplastic Molding?

Manufacturing Services is proud to announce our thermoplastic molding capabilities. Since 2004 we have built our injection molding department to be capable of performing both thermoplastic and thermoset injection molding. Many people are not aware of the advantages of thermoplastic materials. This guide describes the thermoplastic molding process and how it can benefit you.

Thermoplastic Molding

What is thermoplastic molding?

Thermoplastic molding is a reversible molding process by which pellets of plastic are melted, forced into a mold to assume their final shape and then quickly cooled to harden.

Different from thermoset molding

Thermoset molding is the reverse process of thermoplastic. Thermoset molding in an irreversible process in which a chemical change takes place in the material, instead of a physical one .Thermoset material is injected into a hot mold and then cooled to maintain the final shape of the part.

Why Use Thermoplastic Molding?

Thermoplastic injection molding can be used to produce anything from car door panels to cell phone cases with a high degree of accuracy and surface finish. Thermoplastic molding has a very high production output rate, making it quicker than other methods of plastic manufacturing. This means thermoplastic molding is a very cost effective and efficient form of plastic manufacturing. For these reasons, it has become the industry standard for producing plastic parts.

Example of Thermoplastic Molded Parts

Thermoplastic molded products have the tendency to contain greater strength than plastic machined parts.This is due to the ability to add fillers to the base material, adding strength to the finished product. Also, thermoplastic injection molding gives manufacturers the ability to use multiple types of plastic at once, through the use of co-injection molding.

Manufacturing Services utilizes 6 thermoset injection molding machines and 1 thermoplastic injection molding machine.We primarily service the electrical industry, but do and have serviced other industry segments.

All of our products are proudly made in the U.S.A.
