Computer mouse case injection molding machine manufacturer plastic for sale mould production line in China
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.
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.
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.
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.
The new generation mold locking device and computer emulation optimized parameter makes motions of the moving plate, fixed plate and high rigidity toggle structure, the characteristic of high strength and anti-fatigue is secured. As compared with similar machines, it owns bigger internal spur between tie bars, mold space and mold opening stroke and may process plastic products of bigger size.
Short and forceful double-cylinder injection system is used to ensure the steady injection motion.The strain free fixed mold plate and screw assembly with optimized design help to reach better plasticing capacity and effect. PID temperature control regulate the speed and pressure of injection, pressure keeping, smelting, back pressure and other motions to ensure the quality of formed products and continuation of production.Auto material preparation, drooling proof,and anti cold start lapse functions ensure the high efficent,simple and safe operations.
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.
