Abstract:
A method for molding a part comprising the steps of:heating molding materials in a plasticator at a predetermined temperature, said molding materials comprising reinforcing fibers, but no thermosets; mixing said molding materials to create a molten suspension wherein a majority of said reinforcing fibers remain generally undamaged; extruding said molten suspension in order to form a billet; and placing said billet in a compression mold; and compressing said billet with said compression mold to mold a part wherein said reinforcing fibers are distributed throughout said part; and wherein said extruding step further comprises the steps of: sensing the approximate pressure in said plasticator; extruding said billet in said compression mold when said pressure reaches a predetermined pressure.
