KW series high efficiency energy saving variable pump injection molding machine is equipped with high efficiency and high response proportional variable pump system. The power output is automatically matched according to the machine action. There’s no waste of high pressure throttle and overflow power. It has sensitive dynamic following performance. In comparison with the traditional injection molding machine, energy saving reaches 20-40%. At the same time, it saves water and oil 20-40% that greatly increase profit. This machine applies high performance precise oil filter which keeps the oil pollution grate below NAS8 while in normal continuous working.
