This machine series inherits TWX series excellent performance,equipped high performance servo variable speed motive power control system, as well as rotation coder and pressure sensor give the feedback to flow and pressure respectively, the high performance synchronous servo motor give relative flow and plressure adjusting according to rotation speed and rotation torque and carry out accurate close loop control to pressure andflow(mold clamping ,injeciton,lift out etc. the whole machine closes return   loop servo control promote the repsonse speed greatly, the acuracy of repeating up to 1%; the pressure keeping continual test within 10seconds, the pressure average error up to 10kg) is better than traditional plastic injection machine. Having quicker response speed, better energy saving efficiency can save power 20-80%, have the distinguished efficiency for the products which are thick wall, highh precision and long pressure keeping time required. the quick response,reliable performance servo motor motive controlsystem is equipped high precision high sensitive pressure feedback device to form close loop pressure accurate control provide stable quality products to customers. the servo frequency-variable plastic injection machie its maximum output quantity only need 0.05s.compare with traditional, it has quicker responses speed. Shorten the period effectively. In addition,the heating quantity of the amchine is reduced so the hydraulic oil temperature have been reduced and the cooling water using quantity can be reduced to some 30% .Decrease the surrounding noise of the machine. more stable performance for the machine,prolong the using life of hydraulic oil and sealing parts, the cost of machine operation and maintenance are reduced in large scale. And meet the internal environment-friendly strict requirements.
