塑料射出成型制程中，产品翘曲变形量的大小是影响产品质量的主要因素之一。然而产品的翘曲和不均 匀收缩现象是由许多成型加工参数所共同影响的结果。本文将以一车内装饰板为例，藉由 Moldex3D 模流 分析软件进行探讨成形条件对产品翘曲的影响。在此研究中，首先选用不同位置之进浇点来探讨流动平衡 较佳的进浇口位置；然后再运用田口质量实验设计方法来分析影响产品翘曲之最佳适合参数。由分析显示可利用田口 L9（34）直交表进行参数的编排，决定出优化的成型加工参数组合。

Warpage is one of the most crucial problems during the injection molding process, for its great effect on product quality. However, warpage and non-uiform shrinkage are resulted by many molding processing factors. This paper studies a decorative plate of the car for the influence of molding conditions on warpage by using Moldex3D simulation software. First, choose the gate location with better flow balance from different gate locations, and the optimal process conditions by Taguchi method for warpage. It shows Taguchi L9 (34) orthogonal table for scheduling parameters can provide the optimized parameters.
