Where is the 3W UV laser marking machine expensive?

Laser marking machines on the market are mainly divided into three categories. The first category is commonly used carbon dioxide laser marking machines, the second category is fiber laser marking machines suitable for metals, and the third category is ultraviolet laser marking machines. . The price of fiber laser marking machine and carbon dioxide laser marking machine is relatively lower. These two kinds of laser marking machines have a longer service life, are more convenient to maintain, and the environmental requirements are not very high. But the price of the UV laser marking machine will be a bit higher year-on-year, but the relative service life is not that long, and the maintenance is not very good. What is its advantage? Let the price of the UV laser marking machine be relatively high .

UV laser marking machine

The structure of the UV laser marking machine is not much different from that of the fiber laser marking machine. Its hardware facilities include UV lasers, galvanometers, lenses, industrial computers, control cards, workbench casings, electronic control devices, It is composed of power supply, red light, pedal, combined operation mirror and other original parts, so why do you want to pile up fiber laser marking machine, the price of ultraviolet laser marking machine will be so much higher.

UV laser marking machine

From the perspective of optical components, UV laser marking machine and fiber laser marking machine are not universal. In terms of wavelength, the wavelength of fiber laser is 1064nm, while the wavelength of ultraviolet laser is 355nm.

The wavelength of the ultraviolet laser is the wavelength after the frequency is doubled on the basis of the 1064nm wavelength through technology. The technical difficulty is much higher than that of the fiber laser. The high price is higher than that of the ultraviolet laser. Compared with the ultraviolet laser marking of the fiber laser The stability of the machine is worse.

Galvanometer and lens of UV laser marking machine

Compared with the fiber laser marking machine, the galvanometer and lens of the ultraviolet laser marking machine have different coating thickness and materials. Therefore, these two components cannot be used in common. Of course, due to the particularity of the ultraviolet laser marking machine, Therefore, the prices of galvanometers and lenses will also be higher. The common galvanometers on the market have similar lens prices, and the price difference is mainly between UV lasers and fiber lasers.

The laser marking machine is also higher, especially a component called a water-cooled laser

In addition, the use environment of the UV laser marking machine is higher than that of the other two laser marking machines, especially a component called a water-cooled laser, which can only be used when it is kept at a constant temperature. I just mentioned that from the perspective of stability, fiber laser marking machines should be stable with UV laser marking machines. UV laser marking machines require a lot of help from manual after-sales, and labor costs are relatively increased. The fiber laser marking machine only needs remote guidance to operate.

UV laser and after-sales labor cost

Summing up from various aspects, the price of the UV laser marking machine is relatively higher. The higher price is in two aspects: UV laser and after-sales labor costs. How much higher the UV laser marking machine can be? This depends on the price fluctuations of the UV laser. A purely imported high-grade ultraviolet laser needs about tens of thousands of pieces.

Therefore, the price depends on the overall development of domestic UV laser manufacturers and the development of market applications.
