Advantages of UV laser marking machine

With the rapid development of laser technology, the application fields of laser marking machines are becoming more and more extensive, and laser marking machines have also produced fiber laser marking machines, CO2 laser marking machines, and ultraviolet lasers due to various needs. marking machine, etc. As the new favorite of laser marking machine, the price of ultraviolet laser marking machine is relatively more expensive. What are the advantages of the standard machine?

Ultraviolet processing is a kind of cold processing, which mainly destroys the chemical bonds inside the material, so it will have better results in the processing of some plastic materials. Low-power air-cooled narrow pulse width: metal sheet scribing, narrow pulse width marking, can achieve no back marks and deep line depth. Glass engraving, narrow pulse width, can complete engraving in thinner glass (the maximum thickness of glass can be 1mm). The glass back cover of the mobile phone, the low-power narrow pulse width has a better absorption rate of the ink, and there will be no back marks on the ink layer. In addition, the low-power machine adopts air cooling in the cooling method, which has a comparative advantage in volume and is more convenient in installation and use. High power and narrow pulse width: In FPC cover film cutting, the cutting efficiency is fast, and the black edges are less after cutting; glass cutting, ceramic punching cutting, high frequency cutting, fast cutting efficiency, no burr and edge chipping; agate whitening, high frequency marking It should not be broken, and the effect can be kept even on the curved surface.

The main difference between ultraviolet and optical fiber: There will be a lot of heat in the processing of optical fiber, and some materials are more sensitive to heat, so the processing effect of optical fiber is not very good. It is worth noting that UV cold processing will also generate heat, but it will be much smaller than that of optical fibers, because the ultraviolet light will also contain some infrared light, which will also exist in long-term processing (especially ceramic glass) The phenomenon of cracking due to excessive heat.
