The model of hydraulic system is main characterized by high response of the electro-hydraulic servo proportion valve and accumulator of nitrogen used as a standard configuration, which greatly improved the injection molding speed and motion control accuracy and repeatability to meet the high-speed high-precision Injection molding machine performance requirements. 1.System use MOOG system high response servo valve to control injection speed , restain pressure, plasticizing pressure back and to achieve injecting and plasticizing the full closed-loop control.2. To adopt Taiwan's Mirle computer, CPU speed of 32MHz, fast response, dynamic display injection, to achieve complete real-time monitoring, 10.4 "display screen, friendly man-machine interface, easy to use.(3) injection speed: 800mm / s, injection pressure e 250Mpa Suitable for the production of ultra-thin products, V-P exact location of the conversion, the weight of products to repeat accuracy of
