Process for manufacturing an electromagnetic interference shielding metallic foil cladded plastic product

The present invention provides a process and apparatus for manufacturing an electromagnetic interference shielding metallic foil cladded plastic product. The process comprises (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. The final metallic plastic product can not only have as intricate a shape as an ordinary plastic product, but also has a shielding effectiveness as high as an ordinary metallic shield.

Automatic insert injection molding machine

The invention discloses an automatic insert injection molding machine. The automatic insert injection molding machine comprises an injection molding machine body and is characterized in that the injection molding machine body comprises a machine frame; a movable arm is connected to the machine frame, and a taking and placing mechanism and a waste clamping mechanism are connected to the movable arm; a feeding mechanism is further arranged on one side of the injection molding machine body and comprises a vibrating tray used for screening materials and a candidate collecting mechanism used for storing an insert temporarily; the taking and placing mechanism is provided with a grabbing assembly and an adsorbing assembly and used for grabbing the insert on the candidate collecting mechanism and adsorbing and taking out a finished injection molded product. The waste clamping mechanism is used for clamping waste generated during injection molding of the insert. According to the automatic insert injection molding machine, automatic feeding and collecting are achieved, automatic machining is completed, risks and a high error rate of manual operation are avoided, and damage to a die is reduced; in addition, the quality of products is guaranteed and made uniform, production efficiency is greatly improved, labor is reduced, and cost is reduced.
