ABSTRACT:
A fiberglass molding method characterized by the use of a male mask to which glass fiber material is affixed and then sealed against a female mold by a vacuum actuated gasket system. Resin is placed into the bottom of the female mold and is pulled by vacuum through the glass fiber material by means of vacuum ports which extend through the bottom of a spillway and open at an elevation above the bottom of the spillway. The method also allows the resulting fiberglass part to be subsequently surfaced coated using the vacuum method.
