摘要

基于带平板的回形管式气体辅助成型样件对气体穿透行为和残余壁厚与气辅工艺参数的关系进行了研究分析.试验结果表明，气辅工艺参数如气体延迟时间、气体注射压力和熔体预注射量是影响气体辅助成型中气体穿透长度和残余壁厚的重要因素，而各参数间的交互作用致使气体穿透与残余壁厚的变化趋势更为复杂.

Abstract

The gas penetration behavior and the processing parameter determination in gas assisted injection molding(GAIM) was studied.The experiment was performed in a shape tube with a flat surface.And the effects of several important parameters on the remaining wall thickness(RWT)and the length of gas penetration were analyzed.The result revealed that the parameters，such as gas delay time，gas injection pressure and the volume(%) filled melt were the important factors affecting the changes of the length of gas penetration and the RWT in GAIM，and the interaction of these parameters caused variation in the effect of a single parameter.
