What are the cooling methods of UV laser marking machine
Ultraviolet laser marking machine is widely used in plastics because it uses a laser with a wavelength of 355nm, because of its low thermal effect, which can greatly reduce the mechanical deformation of the product. Glass, ultra-fine marking products with high surface laser engraving effect requirements, especially suitable for pharmaceutical and food packaging industry, micro-hole drilling, glass industrial products industry and silicon wafer cutting and other industries.
The UV laser marking machines produced and sold are equipped with two machine types: water-cooled and air-cooled, so what are the advantages and disadvantages in the process of use? The following The production cost and the different areas of use are analyzed separately.
The water-cooling method is that the UV laser marking machine is equipped with a special laser chiller, which can effectively cool, protect the light output rate of the UV laser, and improve the marking quality, and the equipped chiller has a constant temperature and intelligent temperature control. , It is suitable for different regional locations and different use occasions, such as the temperature difference between the north and the south. At this time, the temperature control system of the chiller is particularly important. We know that the temperature in winter in the north is below zero, but the operating temperature of our UV laser marking machine is 10°-30°. At this time, the chiller needs to play its role. The same is true in the summer in the south. Above 35 degrees, it is also necessary to intervene and adjust the chiller at this time.
The equipment of the laser chiller will undoubtedly increase the cost of the manufacturer. According to the chiller with different cooling capacity and different brands, the market price ranges from 3,000 yuan to 10,000 yuan.
The air-cooled UV laser marking machine, as the name suggests, reduces the chiller and integrates the air-cooled UV laser. In terms of volume, it is undoubtedly more compact than the water-cooled UV laser marking machine. Small and light, small footprint, easy to use, comes with a fan to dissipate heat, it is convenient for the integrated control system to be equipped with a temperature detection unit, which can serve the production line processing more safely and efficiently. Mainly used in 3D printing, flying marking, 3c industry. The research and development of air-cooled UV lasers greatly saves the production cost of UV laser marking machines, and has made great contributions to cost savings for both laser equipment manufacturers and users. But the only shortcoming is that the air-cooled laser has very strict requirements on the temperature of the site, and generally requires 15°-30° to play a better effect.
Above, through a simple comparison, I believe you already know how to choose and buy a UV laser marking machine.
