2. Experimental Methodology

2.1 Taguchi Orthogonal Array Design of Experiments

The design of experiments utilizing the orthogonal arrays is, in most cases, efficient and easy to use when compared to the traditional experimental design methods. It is necessary to reduce and to control the number of experiments. Furthermore, a large number of experiments have to be performed when the number of process parameters increases. In this study, 27 FE analyses based on Taguchi (L27) orthogonal arrays were run by utilizing plastic injection process parameters such as the mold temperature (Tmold), melt temperature (Tmelt), injection pressure (Pinj), injection time (Itime), and cooling time (Ctime) as shown in Table 1. The shrinkage parameter corresponds to the response value in developing the regression model. The shrinkage results obtained from FE analyses in Moldflow simulations are provided in Table  2. 塑料注射成型收缩值英文文献和中文翻译(4):http://www.751com.cn/fanyi/lunwen_79121.html
