Screw for injection molding machine
Brief introduction:
Due to the continuous change of plastic application, screw has become one of the key quality of injection molding. In addition to dealing with ordinary plastic products, we have rich experience in the screw manufacturing field of electronic products. In ADDITION TO THE EXISTING screw manufacturing technology, we are also actively developing special surface treatment double alloy screw, and surface coating screw, to meet the changing plastic market demand for high quality screw.
