摘要

Cavity pressure is one of the best indicators of injection molding conditions and thus has been used for quality prediction in the injection molding process. Also, the repeatability of the cavity pressure profile at each shot indicates the consistency of the part quality, which is easily affected by environmental changes, such as barrel temperature. To maintain quality consistency (such as part weight and geometrical dimensions) during mass production, this study proposed a novel method of the holding pressure adjustment to control the deviation in the cavity pressure distribution during each shot. Injection molding of a thin-walled dumbbell-shaped sample was performed to verify the proposed process, which proved the feasibility of this method for suppressing the influence of the barrel temperature changes on part quality.
