The present invention provides a process for manufacturing an electromagnetic interference shielding metallic foil cladded plastic outer shell product. A first side of a superplastic alloy foil is coated with an adhesive and then the foil is placed foil in a first half mold to allow the foil to be initially superplastically formed. A second half mold attached to a nozzle of an injection machine is covered onto the first half mold, and the two half molds are closed to further deform superplastic alloy foil. Softened plastic is introduced from the injection machine to a mold cavity between the foil and the second half mold, such that the superplastic alloy foil covered on the first half mold is completely formed and the softened plastic adheres on the adhesive-coated side of the superplastic alloy foil to form an electromagnetic interference shielding metallic foil cladded plastic outer shell product. Two types of products can be obtained, that is, the superplastic alloy foil can be either the outer wall or inner wall. Moreover, the final metallic plastic product can not only have as intricate a shape as an ordinary plastic product, but also a shielding effectiveness as high as an ordinary metallic shield.
