Conventional Constant Pump Automatic Injection Molding Machine

(Hybrid Type)

break throgh the concept of injection molding machines. Hybrid pump system "X-Pump" is a combination of 2-stage type hydraulic pump and AC servomotor. The servomotor rotates at required speed only when it is necessary to control output volume and pressure of the hydraulic oil.

15 Things to Know About Servo-Driven Injection Machines

Feb 27, 2017 · These machines usually have a constant-speed motor and a variable-displacement pump with a swash plate that can be adjusted by the control to regulate the oil-volume flow of the pump adjusting to the current demand of the hydraulic system. If the machine does not move at all, the pumps will still idle and waste energy. 5.

Injection molding energy-saving & easy

Highly dynamic changes of energy flow to the individual hydraulic loads are typical for injection molding machines during production cycle. Conventional hydraulic concepts with standard engines and standard constant pumps can provide only a constant energy level throughout the whole machine cycle. That does not comply with the requirements of
