Principle of UV Laser Marking Machine

The UV laser marking machine is developed using a 355nm ultraviolet laser. This machine employs third-order intracavity frequency doubling technology. Compared to infrared lasers, the 355nm UV laser has a very small spot size. The marking effect is achieved by directly breaking the molecular chains of materials with short-wavelength laser light, significantly reducing mechanical deformation of the material. Thermal deformation is minimal (classified as cold light), making it primarily suitable for ultra-fine marking and engraving. It is particularly well-suited for applications such as marking on food and pharmaceutical packaging materials, micro-drilling, high-speed dicing of glass materials, and complex pattern cutting on silicon wafers.

Suitable Materials
Mainly used in high-end markets for ultra-fine processing, such as surface marking on packaging bottles for pharmaceuticals, cosmetics, videos, and other polymer materials. The results are extremely fine, with clear and durable markings that surpass inkjet coding in terms of cleanliness and pollution-free performance. Applications also include marking and dicing on flexible PCBs, micro-drilling and blind hole processing on silicon wafers, QR code marking on LCD glass, surface drilling on glassware, marking on metal surface coatings, plastic keys, electronic components, gifts, communication equipment, building materials, etc.
