Abstract
A flash free, compression molded object which includes an insert and is formed using only one mold plate is disclosed. Molding compound is trapped in a mold cavity between the insert and mold plate. An extrusion vent allows excess molding compound and curing gases to escape from the mold cavity. Systems for forming a pin hole within the molded object and removing the molded object from the mold plate are also disclosed.
