Abstract
An automotive triangle trim was chosen as a research model, and the influence of processing parameters was determined with the Taguchi experimental method. An L27 (313) orthogonal array was constructed to investigate the significance of each factor (mold temperature, melt temperature, injection time, V/P switchover, packing pressure, and packing time). The computer-aided engineering software Moldflow was employed to determine the extent of warpage. The influence of processing parameters was analyzed by obtaining the signal- to-noise ratio and by conducting a range analysis. Furthermore, the processing parameters for minimizing warpage were optimized. Subsequently, the optimization packing condition for warpage minimization based on the filling conditions.
