Fiber laser marking machines and carbon dioxide laser marking machines on the market are cheap, have a long service life, are easy to maintain, and have low environmental requirements. So why are UV laser marking machines so expensive? In comparison, the service life is shorter and maintenance is more careful?
The structure of the ultraviolet laser marking machine is the same as that of the fiber laser marking machine. It consists of ultraviolet laser, galvanometer, lens, industrial computer, control card, workbench casing, electronic control device, power supply, red light, pedal, and It is composed of surgical mirrors and other original parts, so how many times the price of the UV laser marking machine is the price of the fiber laser marking machine?
The optical components of fiber laser marking machine and ultraviolet laser marking machine cannot be used universally. 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 multiplication on the basis of 1064nm wavelength through technology. The technical difficulty is higher, which causes the price of UV lasers to be several times that of fiber lasers;
The galvanometer and lens of the ultraviolet laser marking machine are different from the fiber laser marking machine. The coating thickness and material are different, so they cannot be used universally. The galvanometer and lens of the ultraviolet laser marking machine are also more expensive. Of course, the conventional galvanometer on the market The price difference between the lens and the two equipment is not big, the main price difference is between the ultraviolet laser and the fiber laser.
On the other hand, UV laser marking machines have relatively higher environmental requirements, especially water-cooled lasers, which need to be kept at a constant temperature, so they have higher requirements for accessories. Due to the extremely small focusing spot and the small processing heat-affected zone, the ultraviolet laser can perform ultra-fine marking and special material marking. It is the preferred product for customers who have higher requirements for marking effects. In addition to copper materials, UV lasers have a wider range of materials suitable for processing. Not only the beam quality is good, the focused spot is smaller, and ultra-fine marking can be realized; the scope of application is wider; the heat-affected area is extremely small, no thermal effect is generated, and no material scorching problem occurs.
The overall combination results in the relatively expensive price of the UV laser marking machine, which is mainly reflected in the high cost of the UV laser, and the later labor costs are also relatively large.
So the UV laser marking machine is expensive, what is the current price? It is mainly determined by the price fluctuations of UV laser manufacturers. For example, in the early years, there was no UV laser manufacturer in China, and a 3w imported UV laser also required hundreds of thousands. With the breakthrough of domestic technical barriers, 3w UV lasers The price has also dropped significantly. So far, only tens of thousands of renminbi are used for pure imported top-level ultraviolet lasers. Therefore, the price trend of UV laser marking machines currently depends on the development of the overall domestic UV laser manufacturers and the development of market applications.
