Abstract

PROBLEM TO BE SOLVED: To reduce the production cost, to simplify the production process, and to let products have high value-added and reliability, by forming a cap by hardening treatment of the substrate of a silicone rubber and further performing metal plating treatment. SOLUTION: A substrate 1 formed by performing hardening treatment of a silicone rubber key cap is further sprayed or printed with a light transmissible ink layer 2 so that the substrate 1 can be colored as required. Further, a 1st protecting layer 3 is formed by coating the surface of the light transmissible ink layer 2 of the substrate 1 with polycaprolactone resins or acrylic resins. Thus, the surface hardened key cap is provided and further, a metal plating film 4 of nickel, chrome, titanium, aluminium, copper, zinc, silver or gold is formed on the 1st protecting layer 3 by vacuum evaporation plating. Further, a required character or pattern 5 appears on the metal plating film 4 by laser etching and finally, the metal plating film 4 and the character or pattern 5 are covered with acrylic resins or any material in place of them.

題があった。Most of the translucent silicone rubber keycaps or translucent plastic metal film keycaps used for well-known electronic and communication products are made of a plastic such as polycarbonate, acrylic resin or ABS resin, and the base is made of plastic. Then, metal electroplating is performed on the surface, and thereafter, characters or designs are displayed by a method such as laser processing or printing. However, in the former, the translucent silicone rubber keycap is made of silicone rubber translucent material, and its appearance and texture are both inferior to those made of metal.
Since the metal film is formed by plating metal on the plastic and then bonded with silicone rubber, the manufacturing process is complicated and the production cost is high, and the joint between the plastic and silicone rubber is easy to peel off, and the reliability of the product is high. Had a problem.
