UV laser marking is a type of laser marking process. The principle is to use a focused laser beam to mark the surface of various materials. In comparison, UV laser marking machines have smaller and finer focused laser spots, which can achieve ultra-fine marking. The heat-affected zone is very small, the heat effect is relatively small, and there will be no material burning damage. At the same time, it has the advantages of fast marking speed, high efficiency, stable machine performance, and low energy consumption. The range of materials that can be applied is wider.
Advantages of UV Laser Marking Machines
Compared with infrared lasers, UV laser marking machines use a 355nm band and a third-order intracavity frequency doubling technology. When the UV laser marking machine is marking, the laser beam focuses on a very small spot, and the heat-affected zone during processing is very small. This can well reduce the deformation probability of the marking material and is an ideal choice for achieving fine processing. It is mainly used in ultra-fine marking fields, such as food, pharmaceutical packaging material marking, circuit board marking, glass material marking and other application fields.
Most laser applications on the market now use infrared band laser generators, such as CO2, fiber, semiconductor and disc types. In addition, there are green light, ultraviolet light, etc. Among them, infrared laser processing technology is currently the most mature laser processing type and has been widely used in industry. However, green light lasers and UV laser marking machines have great market potential. At present, it has not been fully explored, especially the technology and market development of UV laser marking machines, which hides great potential.
UV laser marking machines are often used for ultra-fine marking of special materials and are the first choice for customers who have higher requirements for marking effects. The high-energy molecules of ultraviolet photons in the UV laser marking machine process directly act on the surface of the workpiece to be processed, quickly completing the separation of molecules on metal or non-metal materials. The heat generated by this working method is very small, which is also one of the differences from traditional laser applications.
UV laser marking machines have better processing effects on product materials, with clear patterns and fine textures. When using UV laser marking machines for processing, the probability of mechanical impact on the material is reduced to one percent, and the processing advantages of fine processing, stable quality, and good processing effect are better presented. It is believed that in the future laser market, UV laser marking machines will usher in more technological breakthroughs and industrial applications.
