摘　　要：以FM卡车顶篷把手件为试验样件,研究确定出气体保压压力、熔体温度、气体保压时间、气体注射延迟时间等四个影响过渡区域气体溶解度的重要工艺参数,通过试验研究确定出这四个工艺参数对制品质量影响的规律,给出最佳成型工艺条件。研究结果用于指导FM卡车顶篷把手件气辅成型的实际生产。When gas is injected into the melt,the important factor of transition region in gas-melt interface is the gas solubility.Gas-melt interface can influence the surface of gas channels and the part quality.For FM truck roof handle,gas holding pressure,melt temperature,gas holding time and gas delay time are the four main processing factors that influence the gas solubility in transition region.The influences of the four factors on part quality were obtained by experimental study,and the optimized processing parameters were determined. The conclusion was applied in the production of FM truck roof handle.
