By means of an extremely focused light beam, the laser marking is applied to a wide variety of objects and materials without contact.
Depending on the laser beam power and the material, the marking is engraved into the material, with more or less material removal taking place. Plastics can thus be marked and cut out in a single step.
Another possibility is annealing marking, in which the surface is heated selectively, resulting in a color change in the material (e.g. steel). This process is mainly used for stainless steel to avoid rust.
Many materials can be lasered with different results, many metals and plastics, wood, stone, even on apples beautiful patterns can be lasered.
