UV Laser Marking Machine

Principle of UV Laser Marking Machine
The UV laser marking machine is developed using a 355nm UV 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 the material with short-wavelength laser light, significantly reducing mechanical deformation of the material. It minimizes thermal deformation (classified as cold light) and is primarily used for ultra-fine marking and engraving. It is particularly suitable 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.

Product Advantages
High beam quality, very small spot size, enabling ultra-fine marking; near-perfect marking quality: 355nm output wavelength reduces thermal impact on the workpiece; galvanometer-based high-precision marking head ensures fine and repeatable processing; high-precision fine spot guarantees perfect marking results; non-contact marking process, permanent marking effect; very small heat-affected zone, no thermal effects, material remains undeformed and uncharred; stable overall machine performance, compact size, low power consumption, fast marking speed, and high efficiency; compatible with production lines for automatic loading and unloading; suitable for marking on most metal and non-metal materials.

Applicable 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 effect is very fine, with clear and durable markings, superior to inkjet coding and pollution-free; flexible PCB board marking and dicing; micro-drilling and blind hole processing on silicon wafers; QR code marking on LCD glass, drilling on glassware surfaces, marking on metal surface coatings, plastic buttons, electronic components, gifts, communication equipment, building materials, etc.
