Laser marking machines use laser beams to permanently mark the surface of various substances. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to engrave exquisite patterns, trademarks and words. The laser marking machines currently used in the market are mainly divided into the following types:

1. Fiber laser marking machine
The fiber laser marking machine uses a fiber laser. The fiber laser has the characteristics of small size (no water cooling device, air cooling), good beam quality (fundamental mode), and maintenance-free.
Mainly used in: marking the required characters, patterns, barcodes and other graphics on plastic, electronics, metal, ceramics, tobacco and other materials.

2. Ultraviolet laser marking machine
The UV laser marking machine is developed with a 355nm UV laser. The 355 UV light has a very small focusing spot, which can greatly reduce the mechanical deformation of the material and has a small thermal effect of processing. It is mainly used in products that enterprises have higher requirements for text and patterns.

3. Semiconductor laser marking machine
The main application industry is the same as the fiber laser marking machine, but as the market competition becomes more and more fierce, the progress of fiber optic technology is getting faster and faster. Now the semiconductor laser marking machine on the market has been slowly replaced by the fiber laser marking machine.

4. CO2 laser marking machine
CO2 laser marking machine is mainly used in some occasions requiring finer and higher precision, such as food, medicine, leather, tobacco, wood products, electronics and other non-metal industries. The effect of marking is more fine and beautiful than the effect of silk screen and inkjet.

5. End pump laser marking machine
The end-face laser marking machine uses a solid-state laser pumped by a semiconductor laser as a pump source, and is coupled with a fiber to inject a laser crystal from the end face. The pump beam entering the gain medium and the cavity mode space overlap to the greatest extent, so that the laser output with high power and high beam quality can be obtained.
The main application industry is also the same as the fiber laser marking machine, and the performance is similar to that of the fiber laser marking machine, but its peak power is higher.

6. Green laser marking machine
Mainly used in glass, crystal products surface and internal marking, ceramics, metal, electronics, plastics and other products. It belongs to the category of cold light, and is also suitable for some products that have a relatively large response to heat and require high precision.

7. Flying laser marking machine
It is a dynamic marking function developed on the basis of the above laser marking machines. It is mainly used in assembly line operations. It can mark products without limitation for 360 days, and can also automatically generate serial numbers and batch numbers, which greatly improves the efficiency of enterprises. production efficiency.
