Abstract
In order to elucidate the mechanism that causes flow mark surface defects, the stabihty of the fountain flow during injection molding is investigated numerically using a transient finite element method. Using a single mode extended Pom-Pom model we demonstrate that the fountain flow instabiUty is an elastic instability.
