THE METHOD FOR MANUFACTURING THE MULTI-LAYERED COPPER-ELECTROFORMED PRODUCT

摘要

A method for manufacturing a multilayered copper-electroformed product that is harmless to the human body while showing a sufficient hardness value and manufacturing a multilayered copper-electroformed product capable of increasing reproducibility greatly when applying a hologram to the surface of the product is provided. A method for manufacturing a multilayered copper-electroformed product comprises the steps of: obtaining a reversed negative second master by plating a first master; plating imitation white gold on the reversed negative second master; plating a cobalt base on the imitation white gold plating layer; plating copper pyrophosphate on the cobalt base plating layer; and separating the new plating layer from the reversed negative second master. The method further comprises: a step of plating chromium on the imitation white gold plating layer after separating the new plating layer; and a forming step performed before the chromium plating step. The method further comprises the step of installing a hologram on the surface of the first master to form a hologram on a negative surface of the second master and the surface of the new plating layer.
