Product Details

PVC Screw for Injection Moulding Machine and Extruder

PVC is a heat-sensitive plastic, and it needs to reach a certain plasticization effect during processing. During the extrusion process, not only the heating, but also the screw thread will give PVC its own frictional  heat, the thread depth above the screw and the screw diameter exsists a specific ratio as well as the compression ratio in order to achieve the effect of plasticization.
