Laser interpretation: What is UV laser marking machine? What role does it have?

What is UV laser marking machine? The ultraviolet laser marking machine has a series of equipments which can be called as the ultraviolet laser laser engraving machine, the ultraviolet laser laser machine and so on, which belong to the laser marking machine. However, the ultraviolet laser with 355nm is different from other laser wavelengths, compared with infrared laser, the machine adopts the third-order intracavity frequency doubling technology. The 355 ultraviolet focused spot is extremely small, which can greatly reduce the mechanical deformation of the material and has little influence on processing heat, because it is mainly used for ultra-fine marking and engraving, it is especially suitable for marking food and medical packaging materials, punching micropores, high-speed division of glass materials, complex graphic cutting of silicon wafers and other application fields. Therefore, the principle is similar to that of laser marking machine, which uses laser beam to mark various material surfaces. The effect of marking is to directly interrupt the molecular chain of matter through short-wavelength laser ( Different from the evaporation of surface matter generated by long wave laser to expose deep matter)So as to show the patterns and words that need to be etched. What role does it have? UV laser marking machine is mainly used in the market of ultra-fine processing, marking the surface of packaging bottles of cosmetics, medicines, videos and other polymer materials, with fine effect and firm marking and cleaning, which is superior to ink code spraying and pollution-free; Marking and scribing of flexible PCB board; Micropore and blind hole processing of silicon wafer; LCD LCD glass two-dimensional code marking, glass surface punching, metal surface coating marking, plastic keys, electronic components, gifts, communication equipment, building materials marking and cutting, etc. However, in the current market, most people purchase UV laser marking equipment mainly for marking UV plastic products, which should be 355NM Cold Light series, therefore, most manufacturers consider a kind of equipment in order that the laser does not harm the surface of the product, and the effect of processing the product materials will get better results and better development. When using cold light laser processing, the probability of material influence has been reduced to 1%, which has fully applied its processing advantages and is also a major improvement in laser technology. It is believed that UV laser marking opportunities will gradually be widely used in the future laser market.
