The UV laser marking machine uses a short 355 nm wavelength that breaks chemical bonds instead of heating the surface. This “cold marking” produces crisp, fine marks with no burning, melting or yellowing — even on white plastic, thin films and glass.
When you need UV instead of fiber
- White or light-coloured plastics where fiber marks look faint or burnt.
- Glass, quartz and sapphire marking.
- Tiny text and 2D codes on PCBs, chips and connectors.
- Medical devices, pharma blister packs, bottles and cosmetics packaging.
Precision you can see
The small focused spot allows micro-text and Data Matrix codes that remain readable by scanners, supporting UDI and traceability requirements.

Frequently Asked Questions
What is the difference between UV and fiber laser marking?
Fiber lasers mark by heating the surface and are best for metals. UV lasers mark with very little heat, giving better results on plastics, glass and heat-sensitive materials.
Is UV laser marking permanent?
Yes. The mark is created in the material itself and does not rub off.
