Overmolding Injection Molding
Overmolding is the precision plastic injection molding process where one material is molded over a second material.
In overmolding, proper material selection is critical – the two plastics do not have to be the same, but they must be compatible.
For example: you should not plan on injection molding the second material onto the first material if the second material will melt or distort the first material. One should not deform the other where it matters.
If the proper materials have been chosen, the two materials bond together chemically and mechanically. This process yields a strong finished piece with a long life.
In some cases, overmolding injection molding can be less expensive than post-molding fabrication.
Our staff works with a wide range of engineered resins and can help you select the best resins and molding process to deliver consistent, reliable product quality.
See below for a few of the overmolding resin materials we work with:
- Glass Filled Nylon
