In-mold coating barrier for a substrate injection orifice

摘要

A substrate having a barrier comprising a raised rim to prevent an in-mold coating from flowing into a gate pin assembly or substrate injection inlet area wherein a substrate is injected into the mold cavity. The barrier prevents cross contamination between a substrate resin orifice and the in-mold coating. A method for isolating an injection inlet area or gate pin assembly from in-mold coatings is also described.
