Abstract
A numerical procedure to simulate the formation of a sink mark near the base of a rib in an injection molded plastic part has been presented. Two commercially available software packages, C-Mold and Abaqus, have been used to predict sink marks. Dependence of sink mark depth on various geometric and molding parameters has been analyzed. The predicted sink mark depth is found to be in good agreement with experimental results from the literature.
