An essential condition for minimizing the cost of quality loss by mass-producing high-quality injection molded products in a short period is the optimization of the injection process condition. As an ASTM D790 flexural strength specimen of PA46 TW341 raw material, molding analysis was performed using the Taguchi method and Minitab to determine the injection weight, which is a factor for optimal quality condition. In addition, the quality of the flexural strength of the specimen was verified by injection molding into the specimen mold and conducting a flexural strength test. The optimum conditions, such as injection time, injection pressure, holding pressure, and holding pressure time, which are key factors of injection molding, were predicted and verified. Good quality was confirmed by evaluating the flexural strength of the injection-molded specimen.
