Laser marking technology is one of the largest application areas of laser processing. Laser marking is a marking method that uses a high-energy-density laser to locally irradiate the workpiece to vaporize or change the color of the surface material, thereby leaving a permanent mark. Laser marking can print various characters, symbols and patterns, etc., and the character size can range from millimeters to micrometers, which is of special significance to the anti-counterfeiting of products.

Principle of laser marking technology

The basic principle of laser marking is that a high-energy continuous laser beam is generated by a laser generator, and the focused laser acts on the printing material to instantly melt or even vaporize the surface material. By controlling the path of the laser on the surface of the material, the required graphic marks are formed.

The focused ultra-fine laser beam is like a tool, which can remove the material on the surface of the object point by point. Its advanced nature is that the marking process is non-contact processing without mechanical extrusion or mechanical stress, so it will not damage the processed items. Because the focused laser beam is small, the heat affected area is small, and the processing is fine, some processes that cannot be achieved by conventional methods can be completed.

The tool used in laser processing is the focused light spot, and no additional equipment and materials are required. As long as the laser can work normally, it can be continuously processed for a long time. Laser processing is fast and inexpensive. Laser processing is automatically controlled by computer, and no human intervention is required during production.

What kind of information the laser can mark is only related to the content designed in the computer. As long as the artwork marking system designed in the computer can identify it, the marking machine can accurately restore the design information on the appropriate carrier. So the function of the software actually largely determines the function of the system.

Lasers can mark almost all parts (such as pistons, piston rings, valves, valve seats, hardware tools, sanitary ware, electronic components, etc.), and the markings are wear-resistant, the production process is easy to automate, and the marked parts are less deformed.

Laser marking technology has been widely used in all walks of life, opening up broad prospects for high-quality, high-efficiency, pollution-free and low-cost modern processing and production. With the continuous expansion of the application field of modern laser marking, the requirements for the miniaturization, high efficiency and integration of the laser manufacturing equipment system are also getting higher and higher. With the successful development of new high-power fiber laser technology, it will be greatly promoted.
