Preparation method for communication equipment metal shell

The invention discloses a preparation method for a communication equipment metal shell and the communication equipment metal shell obtained by the method. The preparation method for the communication equipment metal shell comprises the following steps: 1) providing the metal shell which comprises a metal matrix and a plastic supporting layer attached to the inner surface of the metal matrix; 2) forming more than one narrow slit in the metal matrix by laser etching, wherein the narrow slit penetrates through the metal matrix, and does not penetrate through the plastic supporting layer; and 3) forming a decorative layer on the outer surface of the metal matrix. According to the preparation method disclosed by the invention, the narrow slit with a smooth and burr-free surface can be processed with high precision on the metal shell with the plastic supporting layer, and the metal shell and the narrow silt are not deformed in a narrow slit processing process and a surface decoration process, so that the flatness c
