ELECTROPLATING METHOD FOR METAL FASTENER AND ELECTROPLATING DEVICE FOR METAL FASTENER

WIPO Patent Application WO/2018/109998

A1

The purpose of the present invention is to provide an electroplating method for a metal fastener, the method enabling each element of a metal fastener to be easily plated with high uniformity. Provided is an electroplating method for a fastener chain having a row of metal elements. The method includes a step in which, in a state where each metal element is in contact with a plating liquid in a plating tank, the fastener chain passes through at least one first insulated receptacle in which a plurality of conductive mediums which are in electrical contact with a negative electrode are flowably accommodated. While the fastener chain passes through the first insulated receptacle, principally the surface of the metal elements which is exposed on a first main-surface side of the fastener chain is electrified by coming into contact with the plurality of conductive mediums in the first insulated receptacle. A first positive electrode is disposed in a positional relationship such that the first positive electrode faces the surface of the metal elements which are exposed on a second main-surface side of the fastener chain.
