Abstract
Defect minimization is important in any injection molding process in order to ensure the quality of the injected part or product. The aims of the present study are to determine the optimum processing parameters and to identify the most significant factor during the injection molding process for the lamp holder via Taguchi method. The numerical simulation analysis of injection molding process was carried out by software. The set of numerical simulation for different parameters was designed by L18 Orthogonal array. Six process parameters were considered, which are melting temperature, injection time, cooling time, filling time, injection pressure and filling pressure. The main response of the study is volumetric shrinkage. Main effect and ANOVA analysis were also highlighted in this study. Filling pressure and melting temperature are the most significant factor in the injection molding process of the lamp holder. The present study revealed the setting of process parameters (i.e., 334 °C melting temperature, 0.16 s of injection time, cooling time with 50, 20 s of filling time, 18.65 MPa of injection pressure and 90 MPa of filling pressure) yield the optimum quality of the lamp holder.
