▎ 摘　　要

NOVELTY - Plating film on surface of plastic work piece comprises (i) etching the plastic product to obtain plastic work piece with rough surface, (ii) placing the plastic work piece with rough surface in a vacuum coating machine, using the metal alloy as the target to carry out ion sputtering treatment to obtain plastic work piece with surface deposited metal film layer, and (iii) coating the varnish film layer on the plastic work piece with the surface deposited with the metal film layer. USE - The method is useful for plating film on surface of plastic work piece. ADVANTAGE - The method removes the impurity on the surface of the plastic work piece by etching, improves the bonding force of the metal film layer and the metal work piece, the film layer has strong bonding force, the surface resistivity is low, and does not generate static electricity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for plastic work piece with surface coating, obtained by the above- mentioned method.
