What Materials Can an UV Laser Machine Mark
UV laser marking machines are versatile and can mark a wide range of materials due to their short wavelength (typically 355 nm) and cold marking process, which minimizes heat damage. Here are the common materials they can mark:
1. Plastics & Polymers
Examples: ABS, Polycarbonate (PC), Polyethylene (PE), Polypropylene (PP), PVC, Nylon, PTFE (Teflon), PET, PMMA (Acrylic)
Why UV works well: Minimal thermal damage, high-contrast marks without melting.
2. Metals (Including High-Reflective Metals)
Examples: Aluminum, Gold, Silver, Copper, Titanium, Stainless Steel
Why UV works well: The short wavelength is better absorbed than IR lasers, preventing reflection issues.
3. Glass & Ceramics
Examples: Tempered glass, borosilicate glass, ceramic tiles, zirconia
Why UV works well: Produces smooth, crack-free markings without thermal stress.
4. Semiconductor & Electronic Components
Examples: Silicon wafers, IC chips, PCB boards, LED substrates
Why UV works well: Precision marking without damaging sensitive circuitry.
5. Medical & Pharmaceutical Materials
Examples: Medical devices, pill capsules, surgical tools, silicone
Why UV works well: Non-toxic, sterile marking compliant with FDA/ISO standards.
6. Organic Materials (Food, Wood, Leather, Paper)
Examples: Wood veneer, leather goods, eggshells, food packaging
Why UV works well: No burning or charring, ideal for sensitive surfaces.
7. Composite Materials
Examples: Carbon fiber, fiberglass, coated metals
Why UV works well: Can mark without delamination or surface damage.
