Plastic injection molding manufacturing process produces large quantities of plastic parts with thermoplastic resin. It is a common and important way to make plastic parts. The pellet resin is melted into a liquid form inside the screw at a certain temperature. Then compress the melting in mold cavity in high pressure, the plastic resin forms into solid shape in the mold cavity after a certain cooling time. Finally, the plastic is ejected by the ejection system. Depending on mold structure, part size, resin, part structure, different parts have different cycle time. At Wintech, we can provide high quality and affordable plastic injection molding services.
