Classification and application of laser marking machine

　　Laser marking machine uses a laser beam to make permanent marks on the surface of various materials.

The effect of marking is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks and text.

Laser marking machines currently on the market are mainly divided into the following types:

　　1, fiber laser marking machine

　　 fiber laser marking machine use It is a fiber laser, which has the characteristics of small size (no water cooling device, air cooling), good beam quality (fundamental mode), and maintenance-free.

　　 is mainly used in: marking the required text, pattern, bar code and other graphics on plastic, electronics, metal, ceramics, tobacco and other materials.

　　2, UV laser marking machine

　　UV laser marking machine is developed using 355nm ultraviolet laser.

355 UV light focused spot is very small, can reduce the mechanical deformation of the material to a great extent and has little processing heat influence.

It is mainly used in products that enterprises have higher requirements for text, patterns and so on.

　　3. Semiconductor laser marking machine

　　 The main application industry is the same as that of fiber laser marking machine, but as market competition becomes more and more fierce, fiber optic technology Progress is getting faster and faster.

Semiconductor laser marking machines on the market have been gradually replaced by fiber laser marking machines.

　　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 marking effect is more delicate and beautiful than the silk screen and inkjet effect.

　　5. End pump laser marking machine

　　 End face laser marking machine uses a solid-state laser pumped by a semiconductor laser as the pump source. Inject the laser crystal.

The pump beam enters the gain medium and overlaps the cavity mode space to the greatest extent, so that high-power and high-beam quality laser output can be obtained.

　　The main application industry is also the same as the fiber laser marking machine, and its performance is similar to that of the fiber laser marking machine, but its peak power is higher.

　　6, green laser marking machine

　　 is mainly used in the surface and internal marking of glass, crystal products, ceramics, metals, electronics, plastics and other products.

It belongs to the category of cold light, and it is also very suitable for some products that have a relatively large response to heat and require high precision.

　　7. Flying laser marking machine

　　 is a dynamic marking function developed on the basis of the above several laser marking machines, mainly used in assembly line operations It is possible to mark on products without restriction for 360 days, and it can also automatically generate serial numbers and batch numbers, which greatly improves the production efficiency of the enterprise.

　　 spring back to the earth, in the late spring, laser will continue to meet with you, Yantai, South Korea, Australia...... Looking forward to your visit.
