"Chen Yun coin," Application of laser engraving technology

The common set of commemorative coins positive features of the house and Chen Yun Shanghai Qingpu Revolutionary History Memorial Building, and published the names年号and the "Shanghai Qingpu revolutionary Chen Yun's former residence and memorial hall of history", "100th anniversary of the birth of Chen Yun". 2 logo on the back of the coin were: portraits of Chen Yun during the War of Resistance Against Japan, Baota Mountain in Yan'an; the period of socialist construction portrait of Chen Yun, industrial construction decorative patterns. Also, "Chen Yun" in writing and "1905-2005" character, and included "10 dollars" denomination. "Chen Yun coin" in the back of the logo "Baotashan" and the "Industrial Building decorative patterns" is the application of the laser-engraving techniques. This is the first time the background logo will be laser engraving technology in the production of gold and silver coins, in the domestic as well as the international community are considered first. We know: laser engraving technology is a world-leading technology, applications and uses very broad; laser engraving equipment very quickly in the development, function more complete, it can be said on behalf of a laser engraving of the trends and direction of development . Laser Engraving production is the principle of background patterns: pattern of the background sketch on the scan into the computer, the computer to adjust the pattern of good black-and-white ash levels, and then by computer pictorial instructions will be sent to the laser engraving machines, laser engraving machines under the logo black-and-white ash to control the density of the laser beam, depth, the logo transferred to the mold. Laser Engraving background logo features: It is not like a certain degree of relief as height, but in almost the same plane of screen performance, as in the paper Huasumao entirely from black and white to express the volume of ash flu, and three-dimensional sense. "Chen Yun coin," Application of laser engraving technology background patterns produced before, we have long been studied, explored, and try. CAST 2003, I set up plants produced a silver chapter, in front of my office building factory relief from the top of the combination of many coins semicircular background, it is the application of laser engraving technology production, despite the initial attempt, but the results also good, very fresh, the whole screen is more harmonious. I plant for the 2004 Ink Co., Ltd. was established in the bill and the third anniversary of the completion of the new project also produced a commemorative silver chapter, the same logo on the front, the main factory building from the top of the relief office, the floor of the background research, but also Application of laser engraving techniques, building boats of different makes clear the level of clarity, achieving better artistic effect. "Chen Yun coin" in the production of gypsum-based relief when the background is also embossed with the performance, the judges held that the background embossed with the image of Chen Yun relief levels to do before and after opening, causing Baotashan pressure in the sense of Chen Yun shoulders , the proposed adjustment. We have used laser engraving technology to the production of alternative relief background, and Chen Yun portrait Baotashan background with two kinds of different approaches to performance, highlighted the main themes, structured, we have had good results, the judges received the acclaim. Laser engraving technology, "Chen Yun coin," The successful application of technology to increase the mint means of enriching the gold and silver coins of artistic expression, enhance the level of our mints and capabilities. We believe: the scientific concept of development under the guidance of, with the continuous development of science and technology, mint new technology, new technologies will emerge in an endless stream, and continuously made new progress.
