Many people have such a question about the laser marking machine: optical fiber, green light, carbon dioxide, ultraviolet and mopa machines have little difference in appearance, but the laser light source is different. Why is the ultraviolet laser marking machine so expensive? Why are other types of light sources so cheap? In fact, we should all understand that the price difference of the laser marking machine is nothing more than the difference between the configuration and the later maintenance.
The ultraviolet laser marking machine is composed of ultraviolet laser, galvanometer, lens, industrial computer, control card, worktable shell, electric control device, power supply, red light, foot pedal, surgical mirror and other components. The wavelength of the laser is 355nm, which makes the technology more difficult, so the price of the UV laser is expensive. The galvanometer and lens of the UV laser marking machine are different in thickness and material from those of other light sources, so they cannot be used universally. The galvanometer and lens of the UV laser marking machine are more expensive than other types of light sources.
On the other hand, the UV laser marking machine has relatively high requirements on the environment, especially the water-cooled laser, which needs to maintain constant temperature. Moreover, the stability of the ultraviolet laser marking machine is not as good as that of the optical fiber laser marking machine, which requires the help of manual after-sales service, increasing the cost of manual and after-sales service.
Overall, there are two main reasons for the relatively high price of the UV laser marking machine. On the one hand, the cost of spare parts is high, and on the other hand, the labor cost is high. The stability and life of the UV laser marking machine are not as good as other light sources, so after-sales service is required. Especially after the use of a long time, the power of the UV laser decreases relatively quickly, so the labor cost will rise.
