Optimal injection process parameter analysis for front panel housing using response surface methodology

The quality of plastic products depends on how its looks, whether it follows the intended design or not. Shrinkage and warpage are some of the main defects on the moulded parts produced in the injection moulding process due to the difficulty in adjusting the optimum set of parameter. This study was conducted to determine the optimal injection moulding parameters for minimizing shrinkage and warpage value on front panel housing part. The parameters selected for this study are melt temperature, mould temperature, packing pressure and cooling time. Response Surface Methodology (RSM) of analysis was applied to determine the best set of parameters and the significant factor(s) of the shrinkage and warpage were determined from analysis of variance (ANOVA). The input for this study was obtained through simulation.The quality of plastic products depends on how its looks, whether it follows the intended design or not.
