Laser marking technology in recent years, more and more applications in the field of printing, laser marking can be used, including the plastics and rubber, metal, silicon wafers and other materials. Laser Marking and the traditional mechanical engraving, chemical etching, screen printing, ink printing, etc., compared with a low-cost, high flexibility, you can control the computer system, and the effect produced by the laser mark on the surface of a solid is permanent Its salient features. Currently, the mark in the printing industry, laser marking has occupied more than 90% of the market. Laser Marking occupy such a large share of the reason is because it has the following eight advantages: 1. Permanent: If the marks do not cause environmental relations (touch, acidic and reducing gas, heat, cold, etc.) and subsided. 2. The security: the use of laser marking technology marks carved out and change is not easy to imitate, to a certain extent, has a strong anti-counterfeiting. 3. Non-contact: Laser marking is a non-mechanical "knife" for processing, after the workpiece does not produce stress at any regular or irregular surface of the print mark, and marking to ensure the accuracy of the original piece. The working surface does not produce corrosion, no "tool" worn, non-toxic, non-polluting. 4. Wide applicability: the laser processing means to do, you can variety of metals, non-metallic materials (aluminum, copper, iron, wood, etc.) processing. 5. High precision engraving: laser marking machine engraving pattern of fine items, the minimum line width of up to 0.04mm. Marking a clear, durable and beautiful. Laser marking can meet the printing needs of data on a large number of tiny plastic parts. For example, you can print require more accurate, higher-resolution two-dimensional bar code, marking the way compared with the embossed or injection, there is a stronger market competitiveness. 6. Low operating costs: marking speed and marked a molding, low energy consumption, and therefore lower operating costs. Although laser marking machine for large investment in equipment than traditional marking equipment, but operating costs, the use of laser marking confidential much lower. Illustrates: ① plastic transistor marking: marking machine working speed of 10 / sec to 5 years if the equipment depreciation calculations, marking a cost of 0.00048 yuan / month. If you use a printing machine, its overall operating costs of about 0.002 yuan / month, or even higher. ② bearing surface marking: If the bearing trisection typing, a total of 18 on the 4th word, using galvanometer marking machine to krypton lamp lamp life of 700 hours is calculated, the overall cost of marking each bearing 0.00915 yuan. Electric corrosion lettering costs about 0.015 yuan / month. With annual output of 4 million sets of computing bearings, marking one of only a year at least we can reduce the cost of about 6.5 million. 7. The processing efficiency of the laser beam under computer control can be high speed mobile (speed of 5-7 m / s), marking process can be completed in seconds. 8. develop faster due to a combination of laser technology and computer technology, the user as long as the computer programming to achieve laser printout, and are free to change the print design, replacing the traditional mold making process fundamentally, in order to shorten product upgrades flexible production cycle and provide a convenient tool.
