Why is the UV laser marking machine more expensive?

Many people have such a question about laser marking machines: optical fiber, green light, carbon dioxide, ultraviolet, mopa machine, the appearance does not look very different, but the laser light source is different, why is the ultraviolet laser marking machine so expensive? Why are other types of light sources so much cheaper?


In fact, everyone should understand that the price gap is nothing more than the difference between configuration and post-maintenance. Next, Yiqiang Laser briefly talks about why UV opportunities are so expensive?


Ultraviolet laser marking machine is composed of ultraviolet laser, galvanometer, lens, industrial computer, control card, workbench case, electronic control device, power supply, red light, foot pedal, combined surgery mirror and other original components.


The wavelength of the laser is 355nm, which is more technically difficult, so the price of the ultraviolet laser is more expensive.


Compared with other light sources, the galvanometer and lens of the UV laser marking machine have different coating thicknesses and materials, so they cannot be used universally. The galvanometer and lens of the UV machine are more expensive than other types of light sources.


On the other hand, UV laser marking machines have relatively higher requirements on the environment, and water-cooled lasers need to be kept at a constant temperature. And the stability of the UV laser marking machine is lower than that of the fiber laser marking machine, which requires the help of manual after-sales, which increases the cost of labor and after-sales.


In general, there are two reasons for the relatively high price of UV laser marking machines. On the one hand, the cost of spare parts is high, and on the other hand, it is reflected in labor costs. The stability and life of UV laser marking machines are low. For other light sources, it is necessary to provide after-sales service. After a long time of use, the power of the ultraviolet laser decays relatively quickly, and the labor cost also rises.
