a. The injection unit is the “New double ball screw driven electric injection servo system” developed by Multitech. It not only has the forming accuracy of the general all-electric injection machine , but also greatly reduces the length of fuselage , improves the transmission rigidity and life ,and effectively inhibits the ineffective loss of lubricating oil gas , significantly reducing the loss of lubricant and its pollution.b. The use of advanced aerospace aerogel material as the standard heat insulation barrier for the injection cylinder not only saves energy significantly but also effectively reducesThermal-pollution of production environmentc. All-Electric injection unit are following Euromap and CE requirement；
