Abstract

Abstract: In this paper, the gas penetration behavior in gasassisted injection molding with different delay time is studied by physical experiment and full 3D numerical simulation In the end, the results are analyzed and discussed It was found that the delay time has greater impact on the key factors in determining the quality of products such as the gas penetration length, scale of gas finger and residual wall thickness.
