CHARACTERISTICS of 220 Ton Servo Plastic Injection Molding Machine  · High energy saving In an ideal working state, the machine can save energy 20%-80%, comparing with conventional injection molding machine. · Better molding stability Comparing with conventional injection molding machines, the machine repeatability is greatly improved due to servo motor close-loop control. · Quick response The response time of servo motor is only 0.05 second. · Quiet & low noise The machine runs with low noise, and will be much quiet in a low speed. · Reliable holding pressure The time for pressure holding of the machine will be much longer and more steady, comparing with other electric injection molding machines. · Oil temperature rise slowly Servo motor proportionally delivers hydraulic oil upon user's needs. It can prevent unnecessary heat being generated, in some cases even oil cooling is not required.
