As a modern precision processing method, laser marking technology has unparalleled advantages compared with traditional processing methods such as corrosion, EDM, mechanical scribing, and printing, and is also the most popular among various buyers.
At present, 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.
If you don’t know this marking method yet, let us help you!

What is laser marking?

Laser marking technology is one of the largest application areas of laser processing.

Laser marking can print various characters, symbols and patterns, etc., and the character size can range from millimeters to microns, which has special significance for product anti-counterfeiting.

Basic Principles of Laser Marking

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.

Features of laser marking

It is non-contact processing. It can be marked on any special-shaped surface, and the workpiece will not deform and generate internal stress. It is suitable for marking metal, plastic, glass, ceramics, wood, leather and other materials.

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

Advantages of laser marking

  1. Using laser as the processing means, there is no processing force between the workpiece and the advantages of no contact, no cutting force, and small thermal influence, which ensures the original precision of the workpiece. At the same time, it has wide adaptability to materials, and can make very fine marks on the surface of various materials with very good durability;
  2. The space control and time control of the laser are very good, and the freedom of the material, shape, size and processing environment of the processing object is very large, and it is especially suitable for automatic processing and special surface processing. And the processing method is flexible, which can not only meet the needs of laboratory-style single-item design, but also meet the requirements of industrial mass production;
  3. The laser engraving is fine, and the lines can reach the order of millimeters to microns. It is very difficult to imitate and change the marks made by laser marking technology, which is extremely important for product anti-counterfeiting;
  4. The combination of laser processing system and computer numerical control technology can form an efficient automatic processing equipment, which can print various characters, symbols and patterns, and it is easy to use software to design marking patterns, change the marking content, and adapt to the requirements of modern production with high efficiency and fast pace;
  5. Compared with traditional screen printing, laser processing has no pollution source and is a clean and pollution-free high-environmental protection processing technology;
