Injection Molding Process

Insert Molding

Description

Molding together plastic over a preplaced plastic or metal insert. Insert molding is done by placing inserts or some other material into a mold before the molding cycle. When the plastic is filled into the cavity, the insert is encapsulated securely within the final part.


This process provides parts with enhanced strength or longevity due to the harder material inserted into the plastic. Some examples of insert molding are threaded inserts in plastic housings or electrical connectors.
