Abstract
The effect of the parameters in the injection molding process conditions to the warpage inside the product and the maximum cooling time in the injection molding cycle is numerically considered in this research. A series of process conditions setting with different values of coolant temperature, packing time, and maximum packing pressure has been taken into account. The results indicate that the process conditions have a strong influence on the quality factors– the total displacement of product and the maximum cooling time. In the current model, the optimal process conditions are 50 ℃ of the coolant temperature, 14 s of the packing time, and 77% of the maximum packing pressure. With the optimal parameters, the quality of the product could be improved with low warpage and a short maximum cooling time.
