Abstract:
A process for manufacturing an electromagnetic interference shielding metallic foil cladded plastic product, comprising the following sequential steps of:(a) coating one side of a superplastic alloy plate with a coupling agent or a hot melt adhesive;(b) placing the coupling agent- or hot melt adhesive-coated superplastic alloy plate in a mold, and superplastically forming the superplastic alloy plate to a superplastic alloy foil with a predetermined shape, such that another side of the superplastic alloy foil is attached to the mold and the coupling agent- or hot melt adhesive-coated side of the superplastic alloy foil is spaced apart from the mold to form a mold cavity, wherein an injection machine is attached to the mold cavity, and wherein the injection machine is capable of injecting softened plastic into the mold cavity;(c) introducing softened plastic from the injection machine to the mold cavity, such that plastic adheres on the coupling agent- or hot melt adhesive-coated side of the superplastic alloy foil, and an electromagnetic interference shielding metallic foil cladded plastic product is formed; and(d) removing the plastic product from the mold.
