摘要: 结合CAE及Taguchi DOE技术,研究工艺参数对注塑制品翘曲量的影响。采用了有交互作用的L16(215)正交表设计实验以及没有交互作用的L9(34)正交表设计实验,研究了因素如熔体温度、模具温度、保压压力、保压时间和注塑时间对翘曲影响的显著性。对所选参数,保压压力和熔体温度对注塑制品的翘曲量影响最大。通过两次正交设计实验,使手机上壳制品的翘曲量减少了34.23 %,提高了制品品质。

Abstract: In this paper, CAE and Taguchi DOE(design of experiment) technique were combined to investigate the influence of process conditions on the warpage of injection molded parts. Experiments on L16(215) orthogonal array with interaction of factors and L9(34) orthogonal array were carried out to minimize the warpage of injection-molded parts. For the factors selected in the main experiments, holding pressure and melt temperature were found to be the principal factors affecting the warpage of the injection molded parts. Under the optimum factor levels, the warpage of injection molded parts was decreased by 34.23 %.

Key words: injection molding, process optimum, warpage
