Abstract
Plastic parts are molded for the purpose of mass production in injection molding. Therefore designer is usually designing molds that has geometrically balanced hot runner lay-out for filling balance at cavities. Although, mold is manufactured with geometrically balanced runner lay-out, there are actually filling imbalances in cavities. These filling imbalances phenomenon are caused by complicated interaction between melt and mold. In this paper, filling imbalances for internal gear based on injection molding in hot-runner mold were investigated by CAE and injection molding experiences.
