Variable pump injection molding machine, under the condition of the same speed, by changing the hydraulic pump displacement, at the same time the motor load will also change with the displacement, to achieve the purpose of saving electricity.

The main difference between the variable pump and the standard fixed pump is the output power. The output power of the variable pump changes with the change of the load, while the output power of the fixed pump is relatively constant. In the case of small flow action, the output power of the variable pump is very low , And the output power of the quantitative pump is basically constant.
