Insert molding / over molding

Insert molding involves molding plastic around a core or "insert". Most often, the insert is a metal object, such as a pin, blade, threaded rod, electrical contact, wire, etc. The insert could also be made out of another plastic or composite material—virtually anything that can withstand the heat and pressure of the molding process.

Sunshar has decades of experience with insert molding. With precision metal contact terminal and precision tooling to insure the quality of parts.
