Injection Molding

Guided by our ISO 9000 Certified Quality System, MMT&P injection molding capabilities include insert and over-molding processes.


What is Insert Injection Molding?

Insert molding is a subset of injection molding techniques where metal components are loaded into a mold and then over-molded with plastic to create a part with improved functional or mechanical properties. The insert is precisely positioned inside the mold either manually or by a robotic arm.

One of the most common applications for insert molding is the creation of metal attachment features for fasteners. Fasteners enable assemblies to be securely assembled and disassembled without product damage. Heat-set threaded inserts are molded into plastic to reduce the risks of thread damage during installation. Insert molding can also eliminate the need for fasteners by including the necessary metal parts in the mold, thus firmly securing the parts into a single bonded component.

Benefits of Insert Molding Include:

Overmolding | A Multi-Step Process

Over-molding is a multi-step injection molding process where two or more materials are molded over top of one another to become one part. It’s used across several
industries and serves a wide array of purposes. Examples of over-molding application includes:

The clamp force of our presses range from 90 tons to 400 tons.

Examples of Over-Molding Applications Include:
