Fiber laser marking machines and carbon dioxide laser marking machines on the market are cheap, have long service life, are easy to maintain, and have low requirements on the environment. Why are the prices of ultraviolet laser marking machines so high? In comparison, the service life is shorter and the maintenance is more careful? Today, chuangxuan laser Xiaobian introduced the reason why the UV laser marking machine is expensive.
Why is the price of UV laser marking machine expensive?
The structure of the UV laser marking machine is the same as that of the fiber laser marking machine. It is composed of UV laser, galvanometer, lens, industrial computer, control card, workbench cabinet, electronic control device, power supply, red light, foot pedal, surgical mirror and other components. How many times is the price of the UV laser marking machine?
The optical components of the fiber laser marking machine and the ultraviolet laser marking machine are not universal. The wavelength of the ultraviolet laser is 355nm, the wavelength of the fiber laser is 1064nm, and the wavelength of the ultraviolet laser is the wavelength after frequency doubling on the basis of the 1064nm wavelength. The technical difficulty is higher, which also causes the price of the ultraviolet laser to be several times that of the fiber laser;
The galvanometer and lens of the UV laser marking machine are different in thickness and material from those of the fiber laser marking machine, so they are not universal. The galvanometer and lens of the UV laser marking machine are also more expensive. Of course, the price difference between the conventional galvanometer and lens in the market is not big. The main price difference is between the UV laser and the fiber laser.
On the other hand, the UV laser marking machine has relatively high requirements for the environment, especially the water-cooled laser, which needs to be kept at a constant temperature, so it has high requirements for accessories. Due to its small focusing spot and small processing heat affected zone, UV laser can be used for ultra-fine marking and special material marking. It is a preferred product for customers with higher requirements for marking effect. In addition to copper, UV laser is more suitable for processing. Not only the beam quality is good, the focus spot is smaller, and the ultra-fine marking can be realized; The scope of application is wider; The heat affected area is very small, and there will be no thermal effect and material burning.
In general, the price of the UV laser marking machine is relatively high, mainly reflected in the high cost of the UV laser and the high labor cost in the later stage.
Then the UV laser marking machine is expensive, and how much is the price now? It is mainly determined by the price fluctuation of the UV laser manufacturers. For example, in the early years, there was no UV laser manufacturer in China, and a 3W imported UV laser also needed hundreds of thousands of yuan. With the breakthrough of domestic technical barriers, the price of 3W UV laser also dropped significantly. So far, the pure imported top-level UV laser has only used tens of thousands of yuan. Therefore, the price trend of the UV laser marking machine depends on the development of the overall domestic UV laser manufacturers and the development of market applications.
