On the market, optical fiber laser marking machine and carbon dioxide laser marking machine are cheap, long service life, convenient maintenance and low demand for conditions. So why is the price of UV laser marking machine so expensive? Relatively speaking, the service life is shorter and the maintenance is more careful?
Why is the price of UV laser marking machine very expensive?
The structure of UV laser marking machine is similar to that of optical fiber laser marking machine. It is composed of UV laser, galvanometer, lens, industrial computer, control card, workbench shell, electric control device, power supply, red light, pedal, surgical mirror and other components. How many times does the price of UV laser marking machine is that of optical fiber laser marking machine?
The optical components of fiber laser marking machine and ultraviolet laser marking machine can not be universal. The wavelength of ultraviolet laser is 355nm, and the wavelength of fiber laser is 1064nm. The wavelength of ultraviolet laser is the wavelength after frequency doubling based on 1064nm wavelength by technology. The technical difficulty is higher, which leads to the price of ultraviolet laser is several times that of fiber laser;
Compared with the fiber laser marking machine, the thickness and material of the coating of the galvanometer and lens of the UV laser marking machine are different, so they can not be universal. The galvanometer and lens of the UV laser marking machine are also more expensive. Of course, the price difference between the conventional galvanometer and lens in the market is not large, mainly in the UV laser and fiber laser.
At the same time, the demand for conditions of UV laser marking machine is relatively higher, especially the water-cooled laser, which must maintain a constant temperature, so there is a high demand for spare parts. Because the focus spot of UV laser is very small and the heat affected zone of production and processing is small, it can complete ultra-fine marking and marking of special materials. It is the preferred product for customers with higher demand for marking effect. In addition to copper, UV laser has a wider range of materials suitable for production and processing. It not only has good beam quality and smaller focusing spot, but also can complete ultra-fine identification; Wider scope of application; The heat affected area is very small, which is not prone to thermal effect and material burning.
As a whole, the price of UV laser marking machine is relatively expensive, which is mainly reflected in the high cost of UV laser and the high labor cost in the later stage.
In that case, the UV laser marking machine is expensive. What's the price now? It mainly depends on the price changes of UV laser manufacturers. For example, there are no UV laser manufacturers in China in recent years, and hundreds of thousands of imported 3W UV lasers must be used. However, due to the improvement of domestic technical barriers, the price of 3W UV lasers has also decreased significantly. So far, only tens of thousands of yuan has been used for pure imported top UV lasers. Therefore, the price trend of UV laser marking machine still depends on the development trend of domestic UV laser manufacturers and the development of market application.
