Insert Molding combines metal and plastics, or multiple combinations of materials and components into a single unit. 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.
The metal inserts and bushings are for reinforcing the mechanical properties of the plastic or thermoplastic elastomer products. 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.
Uses For Inserts
A variety of inserts can be molded into plastic components. These include a diversity of magnets, screws, studs, contacts, clips, pins, surface mount pads, rivets, threaded fastners, bushings, tubes, etc. manufactured in materials such as brass, stainless steel, bronze, aluminum, copper, and nickel/nickel alloy.
Insert molded components can be used in housings, instruments, knobs, devices and electrical components for a wide variety of applications in the medical, defense, aerospace, electronics/electrical, industrial and consumer markets.
About The Process
The process itself is the same process used during injection molding. Solid pellets of raw material are melted and extruded into a mold - the plastic is then solidified - and then the press opens and the molded parts are ejected.
Insert molding uses the same materials as the injection molding process. For extreme, high heat, engineered thermoplastics are used. These materials withstand very high temperatures and the components can withstand very harsh environments because of the physical, electrical and chemical properties.
The insert is placed in the mold - either by hand, or by automation before the material is injected into the mold. Then, as the material flows into undercut features in the insert, the insert is anchored much more securely than if it were assembled to a previously molded component.
