Performance Characteristics: Standard designed piping gear end. Screw distributive flow divider, and large flow space ensure enough settling space for the fusion. Best design of low-fusing temperature, the internal stress of piping is small, the interior and exterior surface is smooth. High flexibility, suitable for PO screw intensifying pipe able to coextrude, extrude two layers or three layers different specifications and usage. The entrance of optimization designed copper screw diameter-fixing cover has precooling device and power vacuum device, suitable for the high-speed extrusion of piping. Specially designed shower-cooling steel stainless water tank. High efficiency water pump and special shower nozzle bring high efficiency shower cooling.
