UV Laser Marking Machine

High-Precision, Cold Processing for Ultra-Fine and Versatile Marking

Technology Overview
The UV laser marking machine uses a 355 nm ultraviolet laser generated through third-order intracavity frequency doubling. Unlike traditional infrared lasers, the UV laser has an extremely small spot size and operates via cold processing—breaking molecular bonds directly on the material surface without generating heat. This minimizes mechanical and thermal deformation, ensuring ultra-precise and permanent marking results.

Key Advantages

• Ultra-Fine Marking & Micro-Engraving
  Ideal for detailed graphics, tiny fonts, and high-resolution applications across complex materials.
• Minimal Heat Impact
  The short wavelength allows cold processing with little to no damage to the surrounding material, preserving the original integrity.
• High Beam Quality
  Ensures smooth, sharp, and clear marks with excellent contrast and long-term durability.
• High Precision & Resolution
  The 355 nm laser delivers superior accuracy, making it suitable for delicate surfaces and detailed structures.
• High Speed & Efficiency
  Fast marking speed enables consistent performance in mass production scenarios.

Supported Materials
Widely compatible with a broad range of materials, including:
Plastics, glass, metal, silicone, wood, bamboo, paper, film, resin, ceramics, leather, acrylic, and more.
Also supports creative marking on natural surfaces like leaves, fruit skin, and handmade paper.

Application Fields
UV laser marking technology is used across high-precision industries and custom processing needs, including:

• Electronics:
  Flexible PCB marking and scribing, micro- and blind-hole drilling on silicon wafers, QR code engraving on LCD glass panels, electronic components.
