1. Based on the design of our general purpose machine, we developed the UPVC Powder Injection Moulding machine that assures the strict production requirement of UPVC products. 2.injection molding machine for UPVCfittings have the following features and advantages: GSV Series Injection Molding Machine with Variable Pump This series injection machine adopt high response proportional variable pump, by making output power of the hydraulic system matched with the energy consumption of machine function. It could save electricity by 30% up to 50% compared to ordinary machine.Besides, it could reduce the noise ,prolong working life. Energy saving is much more significant for long molding cycle thick wall product .
