- Abstract
Cavity pressure curve is a comprehensive index for product quality.In this paper-the effects of mold and melt temperatures and holding pressure on the pressure at each point in the cavity was discussed, and the coincidence rate of pressure curve at each point was investigated by using the time-pressure curve of each point.Furthermore-the relationship between the pressure distribution at different points in the mold cavity and the quality of final products was analyzed. The simulation and experimental results indicated that the closer the pressure curves at each point-the better was the uniformity of product quality.The simulation calculation was conducted with a Moldflow analysis software which was commonly used in the injection-molding machine industry. The results obtained in this work provided an important reference for studying the change of cavity pressure and monitoring product quality to ensure a good product consistency.
