Özet

This paper describes a numerical simulation based study of a new injection molding concept focused on locally controlling the filling of multi-cavity molds in real time. The concept is applicable to all runner system types and involves the utilization of controllable mechanical valves. Several types of valve designs in cold runners were modeled and the effects of various control scenarios on localized material conditions throughout the mold are presented.
