ABSTRACT:
A method is provided for forming a net shape molded component that includes an integral metallized coating or layer on the exterior surface thereof. The method includes injecting a carefully matched mixture of a molten polymer resin and a molten metallic alloy into a mold cavity under pressure. Due to the differential in material viscosities, the metal tends to migrate to the outer surface of the molded part when placed under pressure, ultimately creating a net shape molded part having a polymer core with a metallic layer at the exterior surfaces thereof. Further, the present invention provides for the compounding of a feedstock suitable for use in conjunction with the method described above.
