1. Working Principle

A UV laser marking machine works by emitting a high-energy ultraviolet laser beam that breaks molecular bonds on the material surface through a photochemical reaction rather than thermal melting. This “cold marking” process prevents material deformation, burning, or discoloration, making it ideal for precision applications.

2. Main Components

UV Laser Source

Generates ultraviolet laser light, usually at 355 nm. Common power levels include 3W, 5W, and 10W.Galvanometer Scanner (Galvo Head)High-speed scanning mirrors direct the laser beam accurately across the marking area. Field Lens (F-Theta Lens) Focuses the laser beam to achieve uniform marking quality over the entire work area. Control System & Software User-friendly software supports text, logos, barcodes, QR codes, serial numbers, and graphics. Cooling System Typically air-cooled or water-cooled to maintain stable laser performance. Work Table / Rotary Device (Optional) Allows marking on flat, curved, or cylindrical objects.

• 3. Materials That Can Be Marked

  UV laser marking machines are especially suitable for non-metal and heat-sensitive materials, including:

  • Plastics (ABS, PP, PE, PVC, PET)

  • Glass and crystal

  • Ceramics

  • Silicone and rubber

  • PCBs and electronic components

  • Medical-grade plastics

  • Thin films and coatings

  Limited marking on certain metals is also possible with special surface treatment.

  4. Key Features

  • Cold Marking Technology
    Minimal heat-affected zone, no burning or melting.

  • Ultra-Fine Marking Quality
    High resolution, suitable for micro-text and complex graphics.

  • High Contrast and Permanence
    Marks are clear, durable, and resistant to wear and chemicals.

  • Low Material Damage
    Ideal for fragile and high-value products.

  • Non-Contact Process
    No mechanical stress on the workpiece.

    5. Power Range and Marking Area

    • Laser Power:

      • 3W – Fine, micro-marking

      • 5W – General precision marking

      • 10W – Higher speed and deeper marking

    • Standard Marking Area:

      • 110 × 110 mm

      • 150 × 150 mm

      • Custom sizes available with different lenses

        6. Applications

        UV laser marking machines are widely used in industries requiring high precision and cleanliness:

        • Electronics and semiconductor industry
