摘　　要：以精密注射成型聚酰胺66(PA66)/玻璃纤维(GF)接插件为例,采用正交试验和CAE模拟相结合的方法,对影响精密注塑制件收缩率的主要工艺参数进行优化,得到最佳工艺参数组合,并根据PA66/GF的P-V-T曲线,对注射成型的保压阶段进行优化设计,进一步改善了制件的成型收缩率,有效解决实际生产中靠经验确定参数所带来的产品质量不稳定的问题,提高了生产效率和制件质量。The main technological parameters which influence the shrinkage of precision injection molding are optimized using orthogonal test, combining with Moldflow simulation analysis with plastic connector as an example. Further the packing stage is optimized according to the P - V- T curve of PA66/GF to improve the shrinkage of products. The problem of unstable quality of product causing by experience is solved effectively and the productivity effect and product quality are improved.
