Laser engraving and marking is the process of using a high-energy laser beam to irradiate the surface of an object, instantly converting light energy into heat energy, causing the surface of the object to rapidly heat up and evaporate, thereby engraving any desired text, graphics, and images on the surface of the object. The heat generated by the beam will alter the surface of the component or evaporate the surface material. When using steel materials, the temperature in the local area increases, and carbon will escape along the grain boundary area, causing the surface to turn black. For other metals, surface etching occurs while the material evaporates at high temperatures.Laser engraving and marking is a non-contact process that can mark on any irregular surface without deformation or internal stress. It is suitable for various materials such as metal (requiring corresponding lasers), plastic, glass, ceramics, wood, leather, etc; Clear, permanent, aesthetically pleasing markings, and effective anti-counterfeiting measures; It can print various texts, symbols, and patterns. The character size can range from millimeter to micrometer, which is of great significance for anti-counterfeiting of products; It has the advantages of fast marking speed, low operating cost, and no pollution. Compared with traditional marking techniques, laser marking has the following obvious advantages:(1) Fast marking speed, clear and permanent handwriting;(2) Non contact processing, minimal pollution, no wear and tear;(3) Easy to operate and strong anti-counterfeiting function;(4) It can achieve high-speed automated operation with low production costs.This laser marking method is currently the most widely used marking method due to its unique advantages. Mainly used in the medical device industry, electronic device labeling, and consumer product labeling. The marked patterns include Chinese characters, English characters, numbers, graphics, etc. Some developed countries such as the United States have adopted this technology as a process standard for industrial processing, and China also attaches great importance to this technology. The National Science and Technology Commission has listed this technology as part of the "Eighth Five Year Torch Plan" for research and promotion. Luose (Shanghai) Electronic Technology Co., Ltd. will provide comprehensive industrial identification solutions such as laser marking machines, smoke purification systems, and visual inspection, suitable for various industries, including but not limited to: pharmaceutical industry, beverage and food industry, electronic and electronic components industry, Japanese chemical industry, automotive industry, building materials industry, tobacco industry, etc.
