嵌件注射成型工艺的分析与优化

摘要

This paper discussed an insert molding processing optimization case of plastic exterior trim on an automobile body B pillar. The causes of weld line and warpage defects were analyzed based on CAE numerical simulation as well as experiment comparison, and the corresponding optimization suggestions were proposed.%以某品牌轿车车身B柱外饰件为例,分析了嵌件注射成型工艺中熔合纹和翘曲缺陷产生的原因；并通过数值模拟和实验对比,提出了预测和修正制品缺陷的思路和方法.
