摘　　要：采用数值模拟和优化实验方法分析了工艺参数对气辅成型制品气指缺陷的影响。结果表明:影响气指缺陷的重要的工艺参数依次是气体注射延迟时间、熔体温度和气体注射压力;适当延长延迟时间、降低熔体温度和减小气体注射压力可以消除制品的气指缺陷。The effects of processing parameters on gas fingering defect of gas-assisted injection molding product was investigated with the methods of numerical simulation and by optimizing experiment method. The results showed the most important processing parameters that irrfluenced gas fingering were gas delay time, melt temperature, gas injection pressure in turn. Gas fingering defect can be avoided delay time, lower melt temperature and lower gas injection pressure.
