Characteristic
The machine use the high-performance servo dynamic control system, the oil pump as the power source, having the characteristics as follow: high response,saving energy, low noise, high-control precision, and have the breakthrough in the prefect connection of the electrical servo and hydraulic drive system.
High Energy saving
Under the ideal working state, Power consumption is 40% less than that of variable displacement pump and 70% less than that of fixed displacement pump, save the cost effectively.
High precision
Precise control of low pressure & low flow, repeating precision is less than 0.5%. Weight error of the products is 0.4%~0.7%, with semi-close loop system nearly.
Low noise
Different from ordinary fixed pump injection molding machine, servo power-saving injection molding machine is working only when necessary. And working noise is less than 70dB, will be much quieter for your working area.
High efficiency, Energy-saving and high precise proportional pressure and flow variable displacement pump system make the out of the hydraulic system matching the required power for entire machine operation without loss of high pressure throttle and overflow energy. As comparedwith constant displacement pump, t saves power by 30%~60%.A motor with same power may be fitted with an oil pump of bigger displacement and thus accelerates the speed of machine.Besides, the low oil temperature will prolong the service life of sealing elements.
Buffer device is used in every mold opening and clamping oil way to ensure steady mold opening and clamping operation without any impact.Besides, differential mold clamping operation is fitted to ensure high production efficiency.
