Laser marking machines use a laser beam to mark permanent surfaces on a variety of different materials. The effect of the mark is to expose the underlying material through the evaporation of the surface material, thereby carving out beautiful patterns, logos and words. At present, the marking machines used in the market are mainly divided into the following main types:
- Optical fiber marking machine
Fiber marking machines use fiber lasers. Fiber lasers are characterized by their small size (no waterless devices, air cooling), good beam quality (fundamental mode) and maintenance-free.
Mainly used for: marking required characters, graphics, barcodes and other graphics on plastics, electronics, metals, ceramics, tobacco and other materials.
- UV marking machine
UV marking machine is developed using 355nm UV laser. The 355 UV focusing point is very small, which can greatly reduce the mechanical deformation of the material and has little effect on the processing heat. It is mainly used for enterprises that have higher requirements for text, graphics and other products. - Semiconductor marking machine
The main application industry is the same as the optical fiber marking machine, but with the increasingly fierce market competition, the progress of optical fiber technology is getting faster and faster. Semiconductor marking machines on the market have been gradually replaced by optical fiber marking machines. - CO2 marking machine
The CO2 marking machine is mainly used in the occasions that require more precision and higher precision, such as food, medicine, leather, tobacco, wood products, electronics and other non-metal industries. The effect of marking is more delicate and beautiful than that of screen printing and inkjet printing. - End pump marking machine
The end face marking machine uses a solid-state laser pumped by a semiconductor laser as the pump light source, and is coupled from the end face to the laser crystal through fiber coupling. The pump beam enters the gain medium to maximally overlap the cavity modes, resulting in high power and high beam quality laser output.
The main application industry is also the same as the optical fiber marking machine, its performance is similar to the optical fiber marking machine, but its peak power is higher.
- Green marking machine
Mainly used for surface and internal marking of glass and crystal products, ceramics, metals, electronics, plastics and other products. It belongs to the cold light category and is also suitable for products with high thermal response and high precision. - Flying marking machine
It is a dynamic marking function developed on the basis of the above several marking machines. It is mainly used in assembly lines. It can be used for 360 days without limitation in marking on products. It can also automatically generate serial and batch numbers, which greatly improves businesses. Productivity.
