Laser marking machine uses laser beam to make permanent marks on various material surfaces. 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. At present, the laser marking machines used in the market are mainly divided into the following types:
- Fiber laser marking machine
The fiber laser marking machine uses a fiber laser, which has the characteristics of small volume (no water cooling device, air cooling), good beam quality (basic mode), maintenance free, etc.
It is mainly used to mark and engrave the required characters, patterns, bar codes and other graphics on plastic, electronics, metals, ceramics, tobacco and other materials. - UV laser marking machine
The UV laser marking machine is developed by using 355nm UV laser. 355 ultraviolet focusing spot is very small, which can greatly reduce the mechanical deformation of materials and have small processing heat impact. It can be carved on metal, non-metal, glass and other materials. Because the carving effect is exquisite, it is mainly used in products with higher requirements for words and patterns. - Semiconductor laser marking machine
The main application industry is the same as the fiber laser marking machine, but with the increasingly fierce market competition, the progress of fiber technology is faster and faster. Now the semiconductor laser marking machine on the market has been gradually replaced by the fiber laser marking machine. - CO2 laser marking machine
CO2 laser marking machine is mainly used in some occasions requiring more precision and precision, such as food, medicine, leather, tobacco, wood products, electronics and other non-metallic industries. The effect of marking is more delicate and beautiful than that of silk screen printing and inkjet printing. - End pump laser marking machine
The end face laser marking machine uses the solid-state laser pumped by the semiconductor laser as the pump source, and injects the laser crystal from the end face after fiber coupling. The pump beam enters the gain medium and overlaps with the cavity mode space to the maximum extent, so that the laser output with high power and beam quality 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. - Green laser marking machine
It is mainly used for surface and internal marking of glass and crystal products, ceramics, metals, electronics, plastics and other products. It belongs to the category of cold light, which is also suitable for products with high response to heat and high accuracy. - Flying laser marking machine
It is a dynamic marking function developed on the basis of the above several laser marking machines. It is mainly used in assembly line operations, which can mark products unlimited for 360 days, and can also automatically generate serial numbers and batch numbers, thus greatly improving the production efficiency of enterprises.
