利用专用模拟装置，研究了载荷、温度及润滑剂等因素对压射冲头与压室间摩擦力的影响，并根据试验结果及摩擦学原理，对实际压射过程的摩擦特性进行了探讨
The effect of load, temperature and lubricant on the friction force between the injection plunger and the pressure chamber was studied by using a dedicated simulation device. The friction characteristics of the actual injection process were discussed based on the experimental results and the tribological theory
