The method comprises evacuating gas from a preheated resin mixture in an injection accumulator assembly before injection into a mold. The apparatus includes a fixed upper platen assembly supporting an injection accumulator assembly having appended thereto a gas exhausting means and a feed material holding canister on its upper surface and an upper match mold portion on its lower surface. The movable lower platen assembly supports a lower match mold portion on its upper surface and is supported by a plurality of hydraulic cylinders of a bottom plate assembly. The platen assemblies include a sandwich of a press plate, an insulating fiber board and an internally heated platen.
