翘曲变形是塑料注塑工艺中常见的缺陷之一,限制了其在某些精密匹配场合的应用。基于Moldflow软件,以汽车内饰塑料零件为例,分析其翘曲变形的原因,并针对导致零件翘曲变形的关键因素深入剖析,从产品结构、模具、工艺的角度提出了优化改善的方法,有效改善了零件翘曲变形,满足了零件的使用要求。
Warpage is one of the common defects in the plastic injection molding process, limiting its use in some precision matching applications. Based on Moldflow software, the plastic parts of automobile interior are taken as an example to analyze the causes of warping deformation. According to the key factors leading to the warpage of parts, the optimization and improvement methods are put forward from the aspects of product structure, mold and technology. Effectively improve the parts warpage, to meet the requirements of the parts.
