Abstract
A method for forming an elevated surface feature for compression molded assemblies includes the placement of an afore-mentioned insert onto an actuated fixture pin with the pin initially in a retracted position. An upper portion of a mold configured with said retracted actuated fixture pin over a preform of pre-preg plies placed on the bottom portion of the mold is then closed. The fixture pin is actuated towards the pre-preg plies when a flowable material fills a molding cavity in the upper portion of the mold. The cavity is configured to form the elevated surface feature with the advancing action of the insert packs out the surface feature under the pressure of the pin to eliminate porosity in the elevated surface feature in the molding cavity.
