摘　　要：以大屏幕背投电视机为例,探索了不典型塑壁中充气控制、气体辅助注塑成型影响因素和工艺参数协调,分析了各工艺参数调整对成型结果的影响,论述了实践中因素调整思路和方法,得出了欠料和启充延时是强相关因素以及各参数的合理、协调是注塑产品最终品质的保障结论。Taken example for large rear screen TV, gas inflation control in atypical plastic ledgeand influential factors in gas-assisted injection molding were studied. The effects of every pro-cessing parameter adjustment on the results of the molding were analyzed. The adjusting thoughtand method in practice were elaborated. It concluded that absence of stuff and open-fill retarda-tion are strong correlation factors and reason and the coordination of all the parameters are theguarantee of the final product.
