Abstract

Abstract: The core-melt breakthrough was one of common flaw of sandwich injection molding. By means of the software of Moldflow Plastics Insight, the effect of injection rate of core-melt and skin-melt on the tendency of core-melt breakthrough were simulated, and the relation of pseudoplasticity, injection rate and core-melt breakthrough were discussed. It was found that for materials association this paper, the effect of injection rate of core-melt on core-melt breakthrough was different as the materials association was different, while increasing of injection rate of skin-melt even reduced the tendency of core-melt breakthrough.

Key words: sandwich injection molding, front breakthrough, injection rate, numerical simulation
