Overmolding Plastic

Overmolding Injection Molding Services

Plastic OvermoldingOvermolding is the precision plastic injection molding process where one material is molded over a second material.

When overmolding plastic, 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, employing this process can be less expensive than post-molding fabrication.
