UV Laser: cold marking for the most sensitive materials

Where standard Fiber or CO2 lasers are too aggressive, UV laser technology comes to the rescue. Most lasers work on the thermal principle – they heat and vaporise the material. UV lasers, on the other hand, use a shorter 355nm wavelength and work on a photochemical principle. High-energy UV photons directly break the molecular bonds in the material without heating the surrounding area. This process, known as “cold marking”, allows the creation of perfectly clear and contrasting marks without any damage to the material itself.

Why choose a UV Laser?

The UV laser opens the door to areas that were previously inaccessible to laser marking due to the sensitivity of the material to heat.

Unrivalled Precision and Quality

Thanks to the laser’s ultra-small spot size, the UV laser can create incredibly fine and precise details. This allows micro-marking – engraving ultra-small text, intricate logos or high-resolution QR codes – that will be easily readable and flawlessly clear.

Full Protection Against Breaches

The “cold marking” process guarantees that your product will not show any undesirable effects: no scorching, no melting, no foaming or micro-cracking, which often occur when surfaces are exposed to heat. The structure and integrity of the surface of the material remains intact, which is critical in the manufacture of medical devices, electronics or food packaging.

Wide Areas of Application

The UV laser is a versatile solution that fills the niche between Fiber and CO2 technologies. It is ideal where other technologies are powerless.

Spectrum of materials:

• All plastics: ABS, PVC, PLA, polycarbonate, polypropylene and especially silicone.
• Glass and crystal: Marking without risk of micro-cracks.
• Ceramics: precision engraving on various types of ceramics.
• Electronic components: microchip housings, printed circuit boards (PCBs), silicon wafers.
• Medicine: marking of plastic parts of surgical instruments, implants and medical equipment.
• Solar energy: labelling of solar cell wafers.
• It can also mark wood, paper, leather and even metals, giving a different contrast to Fibre Laser.

Examples of use:

• Logo and certification marking on phone chargers, USB sticks.
• Engraving of serial numbers and barcodes on glass containers or labware.
• Marking of identification codes on medical silicone tubing or devices.
• Marking of small schematics and numbers on electronic components.
