Insert Molding Manufacturers

Insert Molding is an injection molding process whereby plastic is injected into a cavity and around an insert piece placed into the same cavity. The result of insert molding is a single piece with the insert encapsulated by the plastic. The insert can be made of metal or another plastic. Insert molding was developed to place threaded inserts in molded parts and to encapsulate the wire-plug connection on electrical cords. Insert molding is also used quite extensively in the manufacture of medical devices. Typical applications of insert molding include insert-molded needle hubs and luer fittings & bifurcations as well as encapsulated electrical components and threaded fasteners.
