Effect of Shear Induced Flow Imbalance on Multi-Cavity Molds Using Gas Assisted Injection Molding

摘要

This paper presents a study on the effect of shear induced flow imbalances on a thick flanged plate molded with gas assist. Samples were molded with and without melt rotation technology and the results contrasted. Flow imbalances and impact on gas distribution and gas penetration were analyzed. Melt rotation technology corrected the flow imbalances seen in multi-cavity tooling and helped gas penetration and distribution.
