| 摘 要： | 对聚醚酰亚胺过滤器壳体注射成型制件的缺陷尤其是开裂缺陷进行分析,发现模具温度的高低直接关系到制件的内应力大小,是引起开裂缺陷的主要原因;指出生产成型温度较高的工程塑料制品时,在工艺设计编制中要对模具温度提出相应的要求,并严格加以控制。

| Abstract: | The defects especially crazing of polyetherimide filter shell produced by injection molding were analyzed. The results showed that mould temperature affected inner stress and it was the main factor inducing crazing defect. It was pointed out that mould temperature should be strictly controlled in the production of engineering plastic products of high molding temperature. |
