Laser marking is possible with our Kolltronic ® laser systems on all metals and plastics (fiber lasers), as well as organic materials (CO2 lasers) that can be lasered.
The upper surface layer of the material is removed and a depression, the engraving, is created. This engraving is smudge and waterproof.
A colour change can be achieved on metals by heating the material. The oxidation process takes place on the surface, so that the material surface remains flat and is not removed. Depending on temperature and material, this oxide layer can turn out not only black but also coloured.
