The UV laser marking machine is developed with a 355nm ultraviolet laser. This machine employs third-order intracavity frequency-doubling technology, which, compared to infrared lasers, results in an extremely small focused spot size of 355nm ultraviolet light. This significantly reduces mechanical deformation of materials and has a small impact on processing heat. It is primarily used for ultra-fine marking and engraving, especially suitable for marking on the surface of packaging materials for food, cosmetics, pharmaceuticals, jewelry, and other polymer materials. The results are precise, the marking is clear and firm that surpass inkjet coding and are pollution-free. It is also used for marking and dicing flexible PCB boards, micro-hole and blind-hole processing on silicon wafers, QR code marking on liquid crystal glass, drilling on glassware surfaces, marking on metal surface coatings, and marking on plastic buttons, electronic components, gifts, communication equipment, building materials, and more.It is the preferred product for customers who have higher requirements for marking effect.

The UV laser marking machine is a product in the laser marking machine series, and it is also a newly developed laser processing technology. Traditional laser marking machines use laser as a thermal processing technology, which has limited room for improvement in precision. However, UV laser marking machines use a cold processing method, thereby minimizing thermal effects and significantly enhancing precision, the probability of affecting the material has been reduced to one percent, and processing the material will result in better results,making it a major leap forward in laser technology.

UV laser processing is considered cold processing because the high-energy molecules of UV photons directly detach the molecules on the metal or non-metal material that needs to be processed.However, this detachment causes the molecules to separate from the material, and this working method does not generate heat.Due to its non heat generating working method, ultraviolet laser processing has become cold processing, which is the difference from traditional lasers.
