Laser Marking / Laser Engraving

Whether marking or engraving: the laser is the perfect tool for marking almost all materials.
The marking is done without mechanical stress. The result is permanent.
Our laser systems are designed for industrial applications and have a high level of precision. A wide variety of materials (metals, light and dark plastics, including PMMA, organic materials such as leather or wood, glass, ceramics, etc.) are marked in the highest quality and with a high level of contrast.
The spectrum of our machines includes CO₂ lasers, Nd:YAG lasers, fiber and diode lasers in various wavelengths: UV lasers (THG), green lasers (SHG), infrared lasers… and different power classes.
A UKP laser will follow soon.
Logos, characters, images, consecutive serial numbers, scales, barcodes, QR and data matrix codes can be placed on your product.
Exclusive branded products from the world’s largest luxury goods manufacturers: With the finest laser spot diameters from approx. 15 µm, we process highly demanding orders, such as parts for mechanical watches or fine writing instruments from famous manufacturers.
Various motorized rotary axes are available for marking cylindrical parts, such as round scales.
Our machine park allows us to process larger faceplates without using a stop and also to produce very precise longitudinal scales or scale disks.
Depending on the machine, we process components up to a size of 870 x 475 x 375 (x/y/z in mm) and up to a maximum of 30 kg.

Laser Marking

The laser beam can create a permanent marking in various ways.
In the case of ferrous metals such as steel or stainless steel and also titanium, a small input of energy into the product surface is enough to leave a change in the structure and thus a locally visible discoloration.
This is known as annealing marking because the laser energy leaves an oxide layer in various annealing colors (e.g. black, yellow, red or green).
A large number of plastics react just as well to punctual laser light. This results in a local color change due to the selective destruction of partial pigments. The choice of the right laser source or the addition of appropriate laser additives is also essential for the result.

Even extremely hard materials, surfaces or coatings (e.g. PVD) are no problem for the laser, in comparison to mechanical processing. In the case of anodized aluminium, the approx. 5…25 µm thick anodizing is vaporized. Paints or powder coatings become discolored or melt away.
Overlapping, homogeneous coatings are differentially separated or recolored with the laser.
The dial shown, for example, consists of four layers:
Brass, PVD gold, black lacquer and white lacquer.
Various types of ceramic, glass, wood and leather can be marked with high contrast using the laser beam.

If in question, you can have your material tested by us for laser qualification, which is usually free of charge.

Another type of laser processing is laser engraving.
The laser light vaporizes material step by step, resulting in a deep structure.
As expensive wearing tools are no longer required, this process is becoming increasingly preferred to mechanical processing. The filigree nature of the laser cannot be achieved with mechanical tools.
Depending on the application, duration and type of material, depths of up to several tenths of a millimeter can be produced effectively. Areas of application can be found in die making (tool inserts, punches) or for high-quality decorative engravings on mechanical watches.
