Adopt high-performance hydraulic components of famous international brands, and use efficient energy-saving hydraulic servo system for clamping, ejection, corn and platen adjustment, etc. with sophisticated and complete corn and un-screwing functions. It can realize linkage clamping and charging, and shorten molding cycle. Perfect combination of servo motor and internal gear pump and closed-loop control that formed through high precision sensors has greatly improved equipment precision. Use optional clamping proportional valve to realize higher position and quicker response.
Charging and injection are directly driven by servo motor. System with ball-screw of famous foreign brands and special axial bearing ensure precise and efficient ejection device. Injection pressure sensor has strong anti-interference and high resolution. Full hard steel alloy screw has high strength, good corrosion resistance and longer service life. Professional self-lubrication system, apply high pressure/heat/ water resistant high performance lubricating grease for injection ball screw. Reserved plastic bearing and synchronous pulley bearing and high load-carrying capacity can extend service life of the machine.
Oil-Electric composite molding machine has maximum precision. It has truly realized high precision and high repeatability full-closed loop control composite operation of pressure, flow and position control.
Rapid Response, High Production Efficiency; High Repetition Accuracy, Save Raw Materials.
Power saving: motor doesn't work during cooling stage, thus power consumption is 0. Water-oil saving: compared to traditional hydraulic power system, reduce 1/4 ~ 1/3 of hydraulic oil consumption; may omit cooling, thus save a large amount of water.
Less Noise Emission: control noise of hydraulic system within national standard scope.
Lower energy requirements for waste heat and cooling, more suitable for production environment with air conditioner; from boot to steady state of
injection molding, the temperature increasing of the oil is about 8°C ~ 10°C.
