Abstract

See full text

A system and process for injection molding polymer articles is described. The system and process are designed to reduce gate blush. In one embodiment, an injection molding device injects a molten polymer composition into a runner that extends from an injection point to a gate. The gate is positioned adjacent to an opening leading into a mold cavity. In accordance with the present disclosure, the system includes one or more overflow passages that divert flow of the polymer composition so as to temporarily reduce the flow rate and pressure of the polymer composition entering the mold.
