Abstract

Products produced via injection molding, even if they have the same shape, can exhibit problems such as deformation and flow imbalance depending on the mold structure, which is determined by factors such as the gate location. In addition to problems with the product, there may be cases where the current mold design cannot be manufactured with the equipment the company has, and injection molding simulation is widely used to predict and prevent this.

In this study, to identify a suitable mold structure by analyzing the effect of the gate location of portable oral products produced via injection molding, a mold structure is adopted based on quantitative data obtained via injection-molding analysis. The results confirm that injection-molding analysis facilitates quality improvement.
