Product Character

Plastic machinery is the plastic molding equipment that used widely today. Its dynamical medium is the high pressure oil that produced by oil pump motor. In the production of different products, the energy waste is too serious. In the every cycle of production, there is mode locking, injection molding, keep pressure, melt adhesive, cooling, etc. working procedure. The pressure, flux of every working procedure are all different, so there is big load difference. The energy waste more especially when light load. 

For dosing pump plastic machinery , to provide invariable current for motor by invariable rotate speed run,  the circumfluence of redundant hydraulic pressure is by flooding valve, the energy waste is big. At the same time,  long-term circumfluence can make hard attrition between hydraulic pressure oil and work,  then it increases the oil temperature, so it affects the lifetime of work.
