Injection molding of electrical parts in today´s materials

It is noted that the molding of electrical components such as bobbins, housing, and bases has become more challenging with the advent of higher heat and electrical property materials such as PET (polyethylene terephthalate), PBT (polybutylene terephthalate), PPS (polyphenylene sulfide), and others. The successful production of these parts is a combination of proper mold design and construction, preparation of molding material, processing, and monitoring of both part parameters and process parameters. Therefore, close communication between the product designer, manufacturing engineer, mold designer, moldmaker, and molder is necessary to achieve successful results. Particular attention is given to the molding of engineering resins, with emphasis on material preparation, melt temperature, mold temperature, molding machine temperature, and quality control
