| titleOfInvention | Mendrel and coins manufactured using the same and manufacturing method thereof |
| abstract | The present invention relates to a mandrel and a coin main body manufactured using the same and a method of manufacturing the same. The present invention is a method for producing a mandrel used as a medium for reproducing the surface of the master, (a) after immersing the master in a nickel-phosphorus plating bath, the electrolytic nickel-phosphorus alloy on the surface of the master Precipitating to form a first plating layer; And (b) depositing nickel on the surface of the first plated layer by electrolysis to form a second plated layer.n n n In addition, the present invention provides a mandrel prepared by the method for producing a mandrel.n n n In addition, the present invention is a method for producing a coin main body for producing a coin main subject by cooperating copper on the surface of the mandrel, (a) manufacturing a mandrel by the method of any one of claims 1 to 8. ; (b) separating the mandrel from the master; (c) depositing copper on the surface of the first plated layer of the separated mandrel by electrolysis to form a third plated layer; And (d) peeling the third plating layer from the mandrel to produce a coin main body.n n n In addition, the present invention provides a coin main body manufactured by the method of manufacturing a main coin.n n n According to the present invention, since the coin bath with the appropriate additives can be used, the surface hardness of the coin main body is greatly improved, so that the coin stock can be released from the mandrel several times without damaging the surface of the mandrel and the coin main body, thereby reducing the cost. It can greatly reduce. |
