Publication number: 20170260638Abstract: A method for manufacturing a composite part of polymer and metal utilizes a mold having a plurality of mold parts and forming a layer of metal on at least one inner or cavity-facing surface of the mold. Thereafter the mold parts are assembled to one another to form a mold cavity defined in part by the layer of metal. The mold cavity is then filled with resin material so that the resin material is in contact with the layer of metal. A curing or hardening of the resin material in the mold cavity is followed by an opening of the mold and the removal of a composite part having a metal shell or outer layer and a polymeric backing or inner layer.Type: ApplicationFiled: March 14, 2016Publication date: September 14, 2017Inventors: Tit Shing WONG, Sui Kay WONG, Wai Choi LEUNG, Si Ping YANG, Siu Wai TANG
