pure gold thin film piece, card having the pure gold thin film piece, and manufacturing method therefor

摘要

A method for manufacturing a pure gold thin film piece according to the present invention comprises the steps of: manufacturing a model in which patterns of a pure gold thin film piece are formed; arranging the model in a manufacturing frame; putting wax in the manufacturing frame in which the model is arranged; separating the model after the wax is hardened; coating conductive materials on an intaglio part of the wax in which the model is separated and formed; extracting pure gold in the conductive materials of the wax and electrodepositing it; separating the pure gold from the wax in which the pure gold is electrodeposited and obtaining a pure gold thin film piece; laminating the pure gold thin film piece, an inlay sheet, an upper overlay sheet, a lower overlay sheet, and a print sheet, bonding them by heat, and a manufacturing a pure gold thin film card.
