Why are UV laser marking machines expensive?

Light thousand laser marking machines and carbon dioxide laser marking machines on the market are inexpensive, have long service life, are easy to maintain, and have low environmental requirements. So why is the UV laser marking machine so expensive? In contrast, shorter service life and more careful maintenance? Today, the editor will introduce to you the reason why the UV laser marking machine is expensive.

Why are UV laser marking machines expensive?

The structure of the ultraviolet laser marking machine is the same as that of the optical thousand laser marking machine. , foot pedal, combined surgery mirror and other original components. So how many times the price of the UV laser marking machine is the light thousand laser marking machine?

The optics of the optical thousand laser marking machine and the ultraviolet laser marking machine cannot be universal. The wavelength of the ultraviolet laser is 355nm, and the wavelength of the light ray is 1064nm. The wavelength of the ultraviolet laser is a frequency-doubling wavelength based on the wavelength of 1064 nm. The technical difficulty is more difficult, resulting in the price of the ultraviolet laser several times that of the optical thousand laser;

Compared with the optical thousand laser marking machine, the thickness and material of the galvanometer of the ultraviolet laser marking machine are different, so it cannot Universal. The galvanometer and lens of the UV laser marking machine are also more expensive. Of course, the price of conventional galvanometers and lenses on the market is not much different, and the main price difference is in the ultraviolet laser and the optical thousand laser.

On the other hand, UV laser marking machines have relatively high requirements on the environment, especially water-cooled lasers, which need to maintain a constant temperature, so the requirements for accessories are relatively high. Due to the small focusing spot and the small processing heat affected zone, the UV laser can perform ultra-fine marking and special material marking. It is the primary product for customers who have high requirements for marking effects. In addition to copper materials, UV lasers are more suitable for processing. Not only the beam quality is good, the focusing spot is small, and ultra-fine marking can be realized; the application range is wider; the heat-affected area is small, there is no thermal effect, and there is no material burning problem.

In general, the price of UV laser marking machine is relatively high, which is mainly reflected in the high cost of UV laser and the high labor cost in the later stage.

So the UV laser marking machine is very expensive, what is the price now? It mainly depends on the price fluctuation of UV laser manufacturers. For example, in the early years, there were no ultraviolet laser manufacturers in China, and 3w imported ultraviolet lasers also required hundreds of thousands. With the breakthrough of domestic technical barriers, the price of 3w UV lasers has also dropped significantly. So far, pure imported top UV lasers only cost tens of thousands of RMB. Therefore, the price trend of UV laser marking machines depends on the overall development of domestic UV laser manufacturers and the development of market applications.
