本文的目标包括最小化的翘曲和下沉指数的塑料件的工艺参数方面具有不同的肋截面类型，和肋布局角度使用田口优化方法。考虑到工艺参数，如模具温度，熔体温度，保压压力，除了肋的横截面类型，和肋的布局角度，一系列的模具分析进行开发的翘曲和下沉指数数据。聚合物材料选择PC/ABS、POM和PA 66。在三水平析因设计的基础上，采用田口优化方法进行模具分析。利用田口正交表、信噪比（S/N）、方差分析（ANOVA）来找到最佳水平以及工艺参数对翘曲和下沉指数的影响。为了验证田口法的优越性，对工艺参数的最佳水平进行了确认分析试验。由此可见，田口方法非常适合于解决热塑性塑料注塑件的质量问题。(C)2005爱思唯尔有限公司保留所有权利。
The objective of this paper consist of minimization of the warpage and sink index in terms of process parameters of the plastic parts have different rib cross-section types, and rib layout angle using Taguchi optimization method. Considering the process parameters such as mold temperature, melt temperature, packing pressure, in addition to rib cross-section types, and rib layout angle, a series of mold analyses are performed to exploite the warpage and sink index data. The polymeric materials were selected PC/ABS, POM, and PA66. Taguchi optimization method was used by exploiting mold analyses based on three level factorial design. Orthogonal arrays of Taguchi, the signal-to-noise (S/N) ratio, the analysis of variance (ANOVA) are utilized to find the optimal levels and the effect of process parameters on warpage and sink index. Confirmation analysis test with the optimal levels of process parameters are carried out in order to demonstrate the goodness of Taguchi method. From this, it can be concluded that Taguchi method is very suitable to solve the quality problem occurring the injection-molded thermoplastic parts. (C) 2005 Elsevier Ltd. All rights reserved.
