Laser engraving technology has the following applications in the production of commemorative coins:
Miniature graphic carving:
Anti counterfeiting label: Tiny text, letters, or patterns are engraved on coin molds using a laser engraving machine. These miniature graphics and text are used on both ordinary commemorative coins and precious metal commemorative coins. For example, in the second round of New Year‘s commemorative coins, there is the word "rmb10yuan" on the front design, and the word "rmb" in floral form on the back of the zodiac animal; In the back design of the 1/2 ounce circular gold coin commemorating the 600th anniversary of Zheng He‘s voyages to the West, issued in 2005, the bottom of Zheng He‘s portrait is covered with miniature text "Imperial Envoy Zheng He", which can enhance the anti-counterfeiting performance of commemorative coins.
Decorative elements: Miniature graphics and text not only have anti-counterfeiting effects, but also have decorative effects. For example, the city wall bricks on the back of the 5-ounce silver coin issued in 2014 for the Second Summer Youth Olympic Games are composed of miniature text, adding unique design elements to the commemorative coin.
Fine carving of patterns:
Display details: Laser engraving can accurately carve complex patterns and textures on the surface of commemorative coins, perfectly presenting the details in the design. Whether it is animal hair, plant veins, or architectural textures, they can all be clearly displayed through laser engraving technology, making the patterns of commemorative coins more vivid and realistic, with stronger layering and three-dimensional sense.
Artistic creation: Providing greater space for the artistic design of commemorative coins, designers can use laser engraving technology to achieve unique artistic effects, such as carving artistic lines, light and shadow effects on the coin surface, enhancing the artistic value of commemorative coins.
Personalized customization: Personalized laser engraving can be performed on commemorative coins according to the specific needs of customers. For example, customizing commemorative coins for specific events, celebrations, or individuals, engraving relevant text, logos, dates, and other information on the coin surface to meet the personalized needs of different customers.
Mold making: In the production process of commemorative coins, the quality of the mold directly affects the quality and accuracy of the commemorative coins. Laser engraving technology can be used to produce high-precision molds, ensuring the accuracy and clarity of patterns and text on the molds, thereby improving the production quality of commemorative coins.
