Abstract
A method is disclosed for molding a part. The method includes steps of heating molding materials in a plasticator at a predetermined temperature; mixing the molding materials to create a molten suspension wherein a majority of the reinforcing fibers remain generally undamaged; extruding the molten suspension to form a billet and then placing the billet in a compression mold and compressing the billet with the compression mold to mold a part. In one embodiment, the reinforcing fibers are distributed throughout the part.
