Insert injection molding combines metal and plastics or multiple combinations of materials and components into a single part.  The process makes use of engineering plastics for improved wear resistance, tensile strength and weight reduction as well as using metallic materials for strength and conductivity.

Insert molding reduces assembly and labor costs, reduces the size and weight of the part, improves component reliability and delivers improved part strength and structure with enhanced design flexibility.

Insert molded components can be used in housings, instruments, knobs and electrical components for a wide variety of applications in the medical, defense, aerospace, electronics/electrical, industrial and consumer markets. 

A variety of inserts can be molded into plastic components.  These include a diversity of magnets, screws, studs, contacts, clips, spring contacts, pins, surface mount pads, rivets, threaded fasteners, bushings, tubes etc. made from materials such as brass, stainless steel, bronze, aluminum, copper, Monel™, and nickel/nickel alloy. 

At Crescent Industries, our engineers can guide you through the steps of the insert molding process from designing a prototype, to building an injection mold, to machining the inserts and injection molding.
