||In-mold assembly uses a rotating stack molds that give designers a variety of options for not only molding multi-component parts but also doing secondary assembly operations inside the injection molding machine. High level molding and full automation is the requisitions of plastic industries. Injection molding combined automation is crucial for molding high class plastic parts. In-mold assembly is the trend of injection molding process in the future, including insert molding, in-mold decoration, co-injection, and bi-plastics injection. In-mold assembly produces a part in the mold that can save the follow operation process.
