Example Embodiment

[0022] The invention relates to a coin, a commemorative coin and a commemorative badge, the surface of which is wavy.

[0023] The production methods of the coins, commemorative coins, and medals, after a large number of experimental studies, believe that the key technology of the wave-shaped medals lies in the engraving and processing of the embossing mold. Round coins, commemorative coins, and medal products are carried out. The relevant parameter of product of the present invention is as follows:

[0024] 1. Product shape and specification: The product is round with a diameter of 13-40mm.

[0025] 2. Selected material: yellow copper alloy or other alloys for coinage.

[0026] 3. The surface pattern is to engrave patterns or characters on the surface of the mold, and the height of the pattern is not higher than 0.1mm.

[0027] 4. The edge of the product adopts two forms with or without edge cleaning.

[0028] 5. The edge of the product adopts smooth edge scrolling.

Abstract

The invention relates to a coin, a commemorative coin, a medal and a making method thereof, in particular to a coin, a commemorative coin, a medal in wave and a making method thereof. The surface of the invention is undulating and the making method comprises the following steps: processing of an impression mold with undulating surface: an organic glass module without patterns is produced in a processing center, an undulating module without patterns is carved by a carving machine, an undulating impression is produced, and then simple patterns and characters are carved in the surface of the impression by a laser carving machine so as to obtain the impression mold; making of a base: the size of the base is slightly larger than the diameter of the product; impression: the produced base is put into the impression mold so as to get a product. The invention has the advantages of good anti-counterfeiting performance, high technical content and enjoyment.

Description

Technical field [0001] The invention relates to a coin, a commemorative coin, a commemorative medal and a manufacturing method thereof, in particular to a wave-shaped coin, a commemorative coin, a commemorative medal and a manufacturing method thereof. Background technique [0002] At present, the coins, commemorative coins and medals of various countries are mostly round, and the surface of the coins and badges is flat. The artistic appreciation of this kind of coins and chapters is poor, the technical content is low, and the anti-counterfeiting performance needs to be further improved. At present, most of the anti-counterfeiting technologies for plane coins and chapters are on the side, such as grooved embossed characters, oblique wire teeth, etc. With the increasing refinement and diversification of mechanical and electrical processing methods, these anti-counterfeiting technologies are becoming more and more easy to imitate; and Although the anti-counterfeiting technolo...
