Laser marking is the most advanced technology for marking industrial products at present. When laser marking does not touch the workpiece, no mechanical deformation occurs on the surface of the workpiece, and high-speed marking can realize on-line real-time marking in the production line. The marking with high precision, fast processing speed and other unique advantages, in the plane, flying round and print various characters, symbols, patterns, serial number, bar code and two-dimensional code, especially suitable for hard, brittle, soft products. Has been widely used in electronic industry, automobile industry, medical products, hardware tools, household appliances, daily necessities, label technology, aviation industry, cards, jewelry processing, instrumentation and advertisement etc.. Typical applications include all kinds of metal and non-metallic materials and products surface marking, such as stainless steel, Aluminum Alloy, organic glass, ceramics, plastics, synthetic materials, wood, rubber, leather, paper products, capacitors and inductors and printed circuit boards, integrated circuits, electrical access card, each kind of instrument and control panel buttons cosmetics packaging, food packaging, stationery, crafts, cigarettes, detonators, bearing, gear, piston ring.
In laser marking machine, carbon dioxide laser, lamp pump, Nd:YAG laser and diode pumped solid laser are mainly used at present. Our own can produce these lasers, but domestic carbon dioxide lasers and laser diodes can not meet the requirements of industrialization, basically rely on imports. Some of the key components in the marking machine, such as Q switches and scanning motors, are mainly imported, but domestic laser marking machines can basically meet the requirements of industrialization and can be used instead of imports. Such as YAG laser Hubei Guangtong Photoelectric System Co Ltd production of marking machine is applied in China Hong Kong joint venture Fujian Changxin Electronics Co. Ltd, replacing the company from Germany imported laser marking machine, laser marking machine is better than imported. It is estimated that the market capacity of domestic laser marking machine is about 2000 units per year, the value of which is about 3~5 yuan.
