Abstract
A method for manufacturing electric appliance casing with inner lining of plastic material or interlayer of superplastic metal alloy for electromagnetic shielding, particularly for adding bolt sleeves, cutting windows, slots and holes, and sealing board rim with plastic material on a plastic casing with superplastic alloy lining or sandwich layers to form a casing that can protect against electromagnetic interference. Under this method, at least one bolt sleeve is placed on superplastic metal alloy plate, and the metal alloy plate is laid over a plastic sheet or sandwiched in between two plastic sheets to form the overlay board. The overlay board is blow molded superplastically with gas in a mold at a selected temperature over the softening point of plastic material and under the melting point of metal alloy. The double-layer or triple-layer overlay board is then trimmed, cut with windows, slots and holes on its surface, and the rims are seal off with plastic material forming the electromagnetic interference shielding casing.
