The basic principle of laser marking is that a high-energy continuous laser beam is generated by a laser generator. The focused laser acts on the substrate, making the surface material melt or even gasify instantly. By controlling the path of the laser on the surface of the material, the required image and text marks are formed.
The laser can mark almost all parts (such as piston, piston ring, valve, valve seat, hardware tools, sanitary ware, electronic components, etc.), and the mark is wear-resistant, the production process is easy to realize automation, and the deformation of the marked parts is small.
Laser marking is characteristic of non-contact processing. It can be engraved on any special surface. The workpiece will not deform and generate internal stress. It is suitable for marking metal, plastic, glass, ceramics, wood, leather, and other materials.
The laser marking machine uses scanning method to mark, that is, the laser beam is incident on two mirrors, and the scanning motor is controlled by a computer to drive the mirrors to rotate along the X and Y axis respectively, and the laser beam is focused and falls on the marked workpiece, thus forming the marks of the laser
1. High engraving accuracy
The products engraved by the optical fiber laser marking machine have fine lines, and the minimum line width can reach 0.04mm. The mark is clear, lasting, and beautiful. Laser marking can meet the needs of printing a large amount of data on very small plastic parts.
The mark engraved by laser marking technology is not easy to copy and change and has strong anti-counterfeiting properties.
Laser marking is a non-mechanical "light knife" for processing, which can print marks on any regular or irregular surface, and the workpiece will not generate internal stress after marking, so as to ensure the original accuracy of the workpiece. There is no corrosion, abrasion, poison, and pollution to the working surface.
4. Wide applicability
Laser processing can be applied to a variety of metal and non-metal materials (aluminum, copper, iron, wood products, etc.).
5. Fast development
Because of the combination of laser technology and computer technology, users can realize laser printing output as long as the program on the computer and can change the printing design at any time, fundamentally replacing the traditional mold manufacturing process, providing a convenient tool for shortening the product upgrading cycle and flexible production.
6. Low operating cost
The marking speed is fast and the mark is formed at one time, the energy consumption is small, so the operation cost is low.
7. High processing efficiency
High processing efficiency and fast marking speed. The laser beam controlled by a computer can move at high speed (up to 5-7m /s), and the marking process can be completed in a few seconds.
The laser mark will not disappear due to the environmental relationship (touch, acid, and reducing gas, high temperature, low temperature, etc.).
