摘要/Abstract

摘要： 选用L27(313)正交表设计实验，研究模具温度、熔体温度、充填时间、保压压力和保压时间以及三个两因素交互作用对多型腔模具PP塑料制品每个型腔体收缩率的影响程度。对于所选参数，模具温度和保压时间对体收缩率的影响是高度显著的，熔体温度和保压压力对体收缩率的影响是显著的。在优化工艺组合下体收缩率降低了21.46％。

Abstract: L27(313) experiments were performed in order to determine an optimum condition for minimizing the volumetric shrinkage in multi-cavity injection molding part of polypropylene (PP). It showed that the mold temperature and packing time had the greatest influence on the volumetric shrinkage. Based on a standard analysis of variance(ANOVA), it was found that the relative significance of the factors on the volumetric shrinkage was in the descending order: packing time, mold temperature, melt temperature, and packing pressure. Using the optimized level of factors, the volumetric shrinkage was decreased by 21.46％.

Key words: multi-cavity injection molds, process optimum, volumetric shrinkage
