    AI Overview
    355nm UV laser marking is a high-precision, "cold marking" process ideal for plastics because it breaks molecular bonds with minimal heat, preventing deformation or burrs. It works by high absorption of the ultraviolet light, enabling high-contrast, permanent, and detailed marking (even micro-texts or QR codes) on sensitive plastics like polyethylene and polycarbonate. 
    Key Advantages for Plastics 
    • Cold Marking Technology: Because it uses low thermal impact, it prevents melting, burning, or damaging delicate plastic components.
    • High Contrast: Ideal for high-contrast markings on various plastics, including white, black, and transparent, without requiring additives.
    • Precision: Provides extremely fine focus spots for detailed graphics and small text.
    • Material Versatility: Effective on PE, HDPE, PVC, EVA, ABS, and flame-retardant materials. 
    Common Applications 
    • Electronics & Medical: Marking on 3C products (phones, computers) and medical plastics.
    • Packaging: High-contrast codes on food and pharmaceutical packaging.
    • Industrial Components: Precise marking on connectors, switches, and plastic casing. 
    Key Considerations 
    • Power & Efficiency: Typical setups utilize 3W, 5W, or 10W lasers, depending on the speed and depth required.
    • Safety: UV lasers require enclosed systems to prevent skin/eye exposure. 
    Commonly available systems, such as those discussed in, can be found via suppliers, allowing for high-accuracy marking that traditional fiber or CO2 lasers cannot achieve.

    Can plastic be laser marked?
    Laser marking is a reliable and cost-effective technique often used to mark plastic parts. By precisely laser etching plastic surfaces, this equipment produces permanent, high-quality marks. These markings also cause minimal distortion and are resistant to chemicals, abrasion, and extreme temperatures.

    What happens if you laser engrave PVC?
    Hydrogen Chloride and Vinyl Chloride (mostly found in PVC and other man made materials) are hazardous to the life of your laser system. Engraving and cutting these materials can cause irreversible damage to your machine, so determining the components of your cutting and engraving materials is extremely important.

    What materials are unsafe to engrave and/or cut with the laser?
