Injection & Blow Molding

Hydraulic servo and proportional control systems are widely applied in injection molding and blow molding industries. Featuring high response frequency, precise motion control and powerful clamping force output, hydraulic servo systems are core to large-tonnage injection molding machines and blow molding equipment. The system realizes accurate parison wall thickness control and precise clamping force adjustment, effectively stabilizing finished product quality, reducing defective rates and achieving efficient production cost control.

With years of industry cultivation and technical accumulation, our company has established long-term and stable cooperative partnerships with a large number of injection and blow molding manufacturers. We provide full-range professional repair and overhaul services for core hydraulic components and supporting equipment in the molding industry, including injection clamping servo valves, mold opening and closing servo valves, ejector valves, feed valves and travel control valves, as well as multi-unit extrusion pumps, hydraulic motors, servo motors and Roots blowers. With reliable repair quality and high-standard after-sales service, we have replaced many unstable suppliers for our clients and established exclusive long-term strategic cooperation with numerous enterprises.

Our professional maintenance scope covers mainstream brand servo valves and proportional valves such as MOOG G631, D681, D682, D684, D634 and Rexroth 4WRPE10 series. We also provide comprehensive repair services for five-star hydraulic motors, general hydraulic motors, extrusion pumps, multi-series tandem pumps, vane pumps and plunger pumps, as well as professional overhaul for servo motors & controllers, blow molding controllers and particle conveying Roots blowers.
