HXV Series Variable Pump Drive Injection Moldine applies high responsive proportional variable pump system, thus to enable the high match of the system of injection molding machine's output power and machine effective operation, compared with normal machine, saving electricity of 30%~50%. In addition, it also can debase peripheral noises and extend machine's life span, which is fit for producing long time molding cycle and thick-walled products, energy-saving is much more obvious
