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 a workpiece, causing the surface material to vaporize or undergo a chemical reaction of color change, thus leaving a permanent mark. Laser marking can hit a variety of text, symbols and patterns, etc., the character size can be from millimeters to micron scale, which has a special significance for the anti-counterfeiting of products.

Basic principle:

The basic principle of laser marking is that a continuous laser beam of high energy is generated by a laser generator, and the focused laser light acts on the bearing material, causing the surface material to melt instantly, or even vaporize, and by controlling the path of the laser light on the surface of the material, thus forming the desired graphic mark.

Considerations related to the permanence of laser marking:

Stability: Once laser marking is completed on the surface of a material, the mark is relatively stable and durable. Laser marking cannot usually be easily erased or altered.


Durability: The durability of laser marking depends on the characteristics of the material and the parameter settings of the laser marking. For some non-metallic materials, such as plastic, glass, metal, etc., laser marking usually has a high durability.

Resistant to abrasion: Compared with traditional printing marking methods, laser marking is usually less susceptible to abrasion, fading or peeling, and can maintain clarity and readability for a long time.


Environmental impact: the permanence of laser marking is also affected by environmental factors, such as ultraviolet light, chemicals, high temperature, etc. may have an impact on laser marking.
