基于注塑件翘曲优化及影响因素分析

随着信息产品和电子产品的发展，对注塑制品的质量提出了更高的要求，如轻便、小巧等，这就促使了薄壳制品的出现。由于制件的壁薄（一般为1-2mm），所以更容易出现收缩、翘曲、残余应力等缺陷。对于薄壳制品而言，翘曲变形形严重影响制品的质量。本文就翘曲变形进行探讨分析。

Optimization of injection molded parts based warping and influencing factors

With the information products and development of electronic products, plastic products for a higher quality requirements, such as lightweight, compact, etc., which prompted the emergence of a shell products. Because of the thin wall parts （usually 1 - 2 mm）, it is more prone to shrinkage, warping, residual stress and other defects. For shell products, the warpage shape seriously affect the quality of products. This paper discusses the warpage analysis.
