A lot engineers rely on production experience and intuition to control process parameters and product quality for injection molding. Also a large amount of manufactures usually solve problems of mold design and molding process by trial and error. It doesn’t always satisfy the needs of users. In this study, Taguchi method incorporated with analysis of variance is used to find out the influence of each parameter and optimal combination of process parameters in adornment injection molding. Also the computer-aided engineering (CAE) software MoldFlow is used to analyze the injection molding process. The process parameters under discussion are back pressure, melt temperature, mold temperature, injection speed, injection pressure, packing pressure, packing time, and cooling time. The packing time, cooling time and packing pressure are the most important factors.
