    AI Overview
    355nm UV laser cold processing is a high-precision technique using ultraviolet light to break molecular bonds (photolysis) rather than using heat. This "cold" method avoids burning or melting sensitive materials, creating exceptionally clean marks. It excels at marking/cutting plastics, glass, and thin metals with a small, 0.002mm - 0.02mm spot size. 
    This video demonstrates how the UV laser cold processing works:

    Key Aspects of 355nm UV Laser Processing: 
    • Process - "Cold" Ablation: Unlike fiber or CO2 lasers that rely on heat, UV lasers directly break molecular bonds. This results in minimal heat-affected zones (HAZ) and no carbonization on sensitive materials. 
    • High Precision: With a 355nm wavelength and a typical spot size of 0.002 mm, UV lasers offer superior precision for intricate engraving. 
    • Materials Supported: Widely used on plastics (ABS, PC, PVC), glass, ceramics, thin metals, leather, and fabric. 
    • Applications:
      • Electronics: Marking circuit boards, keyboards, and components.
      • Medical/Industrial: Barcoding and serializing sensitive medical devices and plastic tools.
      • Glasswork: Sub-surface engraving in glass. 
    • Limitations: UV lasers are generally not suited for deep engraving on metals.

    Advantages of 355nm UV Technology: 
    • Minimal Thermal Impact: Drastically reduces melting, warping, or burning.
    • Broad Material Compatibility: Processes materials that are otherwise unsuitable for laser marking.
    • High-Quality Results: Produces high-contrast, permanent marks.

    Does the UV laser really work?
    High Precision: UV lasers offer incredible precision because of their tiny laser spot. Their wavelength is much smaller than infrared and visible lasers, which is why they can target a tiny area. They offer intricate details and reach up to nanometer-level accuracy.Apr 16, 2026

    Does temperature affect laser engraving?
    During the laser processing of metal, it is continuously affected by heat. Prolonged high temperatures may cause the metal to warp or deform. Temperature changes will also alter the color of the engraved area on the metal surface. The engraved areas will change color as heat accumulates.
