Laser Marking

Laser marking technology is one of the biggest applications of laser processing. Laser marking is the use of high-energy laser of the workpiece on the local irradiation, the surface material vaporization or color change of the chemical reaction, leaving a permanent marking of a marking method. Laser marking can play a variety of text, symbols and patterns, the size of the characters can be from the order of millimeters to microns, which have special significance for the security of products.

The basic principle of laser marking is that the laser generator generates high-energy continuous laser beam. The focused laser beam acts on the printing material to melt and even vaporize the surface material instantaneously. By controlling the path of the laser on the surface of the material, The required graphic tag. Laser marking is characterized by non-contact processing, it can almost all parts (such as the piston, piston rings, valves, seats, hardware tools, sanitary ware, electronic components, etc.) marking and wear-resistant marking, production process easy The automation is realized, and the marked part is deformed little.

Laser marking technology as a modern precision machining methods, and corrosion, electrical discharge machining, mechanical characterization, printing and other traditional processing methods, compared with unparalleled advantages:

1. It has the advantages of no contact, no cutting force and little thermal influence, which ensures the original accuracy of the workpiece. It has the advantages of no machining force between workpiece and workpiece. At the same time, the wider adaptability of materials, in a variety of materials on the surface to produce fine marks and good durability;

2. Laser space and time control is very good, the processing object material, shape, size and processing environment are very large degree of freedom, especially for automatic processing and special surface processing. And flexible processing methods, both to adapt to the needs of laboratory-style single-design, but also to meet the requirements of industrial mass production;

3. Laser scribe fine lines can reach millimeters to microns level, the use of laser marking technology to make the mark to copy and change are very difficult, very important for product security;

4. Laser processing system and computer numerical control technology can be combined to form an efficient automated processing equipment, you can play a variety of text, symbols and patterns, easy to use software design marking patterns, change the contents of tags to adapt to modern production of high efficiency, fast pace requirements;

5. Laser processing and traditional screen printing compared to no pollution, is a clean and pollution-free high-environmental processing technology.
