采用節(jié)能及比例壓力流量變量泵系統(tǒng)，令注塑機(jī)液壓系統(tǒng)輸出與整機(jī)運(yùn)行所需功率匹配。無高壓節(jié)流溢流能量損失，與定量泵相比，節(jié)電30%~60%，相同功率的電機(jī)可配用更大排量的油泵，令整機(jī)速度加快，同時(shí)低油溫使用壽命長，同時(shí)液壓系統(tǒng)正常工作。在開合模油路中，均采用了緩沖裝置，開合模平穩(wěn)無沖擊。并設(shè)有差動(dòng)合模動(dòng)作，生產(chǎn)效率高。

      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 compared with constant displacement pump, it 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 wi-ll prolong the service life of sealing elements. Use of imported high performance precise oil filter device will further prolong the normal service Life of hydraulic oil and also ensure the normal operation of hydraulic system. Buffer device is used in every mo-ld 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.
