Water-cooled 355nm ultraviolet laser marking has more advantages than air-cooled fiber laser marking

Ultraviolet laser marking machine is the most widely used equipment for packaging and coding, such as cosmetic bottles, 3C electronics, switches, bathrooms, etc., will use ultraviolet laser marking machines. Generally, there will be a small water tank next to the ultraviolet laser marking machine. , What is the purpose of this small water tank, why is there no fiber laser marking machine?

During the operation of the 355nm ultraviolet laser marking machine, it will heat up at high temperature due to long-term operation, so the chiller needs to be cooled by circulating water to control the temperature within a certain range, which can prolong the working life of the 355nm ultraviolet laser marking machine. And improve the marking accuracy, so that the 355nm ultraviolet laser marking machine will not be damaged due to long-term high temperature heating, so this water tank is the cooling system of the 355nm ultraviolet laser marking machine.

Why doesn't the fiber laser marking machine have a water tank? This is because the cooling system of the fiber laser marking machine is air-cooled, and the heat dissipation problem can be solved by using the built-in fan, while the CO2 laser marking machine is both air-cooled and water-cooled.

Ultraviolet laser marking machine can mark plastic, metal, silica gel, glass, PP, rubber, and can engrave on glass or crystal material well. Compared with traditional glass processing technology, ultraviolet laser marking machine makes up for the past. The processing accuracy is not high, the drawing is difficult, and the environment is polluted. The 355nm ultraviolet laser marking machine adopts non-contact processing, so that the glass surface will not be damaged by external force, and will not produce cracks. It is cold processing, with high beam quality and very small light spot. It can be well used for fine marking on glass or crystal surfaces.
