High-Effciency Energy-Saving Plastic Injection Molding Machine

High-effciency Energy-saving Plastic Injection MachineFeatures: SZ series moulding machine of oil-electric compound system control series is the product newly developed by Guangsu Company with features of economic benefits, energy saving, high response and low noise. Structure principle: During actual working status, the system directly feedbacks the pressure-flow rate signal through exit pressure sensor of oil pump and cycloscope to the high speed servo driver. The servo driver gives out electric signal to servo driving motor and oil pump, allowing for corresponding change of pressure and flow rate, therefore, the closed circuit control of pressure and flow rate is realized. High-effciency Energy-saving Plastic Injection MachineAdvantages: Energy-saving: Super low energy consumption, saving energy about 30% as compared to load sensitive variable pump, and about up to 80% as compared to constant flow pump, and its energy saving effect is comparable to the fully electric forming machine. Low noise: Reduce greatly the noise produced by pressure control operation. Reducing cost for long term: Realize energy saving and reduce running cost. Compared to electric type, the initial investment and maintenance cost is reduced greatly. Easy operation: Parameters setting and system speed adjustment are very simple digital operations. The customer only needs to operate the control panel just like common machine. High performance: High response (30ms-130ms), high stability, accurate repeatability and energy saving.
