摘　　要：以21英寸彩电前壳为例,将Moldflow 2010作为CAE模拟试验平台,以熔体温度、模具温度、熔体注射时间、气体延迟时间、气体压力为关键工艺因素,考察了气体辅助注射成型时制品的翘曲变形量和气体穿透情况。采用正交试验法及极差分析法对Moldflow模拟试验结果进行分析,确定并验证了较优工艺参数组合的正确性。The 21 inches color TV front cabinet was used as an example and Moldflow 2010 software was used for CAE platform, the gas penetration degree and warp effect of parts during gas-assisted injection molding（GAIM） were investigated with melt temperature, mold temperature, melt injection time, gas delayed time, and gas injection pressure as the key process parameters. The CAE results were analyzed by orthogonal method and range analysis. The optimum parameters was determined and then verified that it was reasonable.
