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 ultraviolet 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 food and pharmaceutical packaging materials.

Product Advantages
High beam quality, extremely small spot size, enabling ultra-fine marking; near-perfect marking quality: The 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 marking results; non-contact marking process ensures permanent marking effects; very small heat-affected zone, no thermal effects, material remains undeformed and unburnt; stable overall machine performance, compact size, low power consumption, fast marking speed, 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 ultra-fine processing markets, such as surface marking on packaging bottles for pharmaceuticals, cosmetics, food, and other polymer materials. The effect is extremely fine, with clear and durable marks that are superior to inkjet coding and pollution-free; flexible PCB marking and dicing; micro-hole and blind hole processing on silicon wafers; QR code marking on LCD glass, drilling on glassware surfaces, marking on metal surface coatings, plastic keys, electronic components, gifts, communication equipment, building materials, etc.
