Laser marking

Laser marking makes it easy to apply unique and durable markings to components. The laser ensures that the marking process is completely contact-free. This protects the material, increases effectiveness and productivity, and thus the benefits. Laser marking is also a first-class solution for component marking and, by eliminating the need for additional materials such as ink or paint, makes a perfect contribution to sustainability. A very future-proof process for your applications too.

Laser marking can be used to mark or label almost all materials. Laser marking is achieved by a focused laser beam that is directed onto the surface of the material to be marked. Since laser marking is completely contactless, there is no mechanical stress on the material or the object to be marked that could cause damage. When laser marking metal (stainless steel and aluminum), we generally distinguish between two process techniques that are considered the most important and therefore the most significant: annealing and ablation with the special feature of engraving.
Laser annealing marking utilizes the typical reaction of metal surfaces, especially steel, to heat in order to create a marking. This is because these materials display annealing colors when heated with a laser. The reason for this is the oxide layers that form on the surface during heating, the properties of which determine the color impression. A major advantage of annealing markings is that the surface remains completely untouched. This method is used wherever the installation or construction situation requires a high-precision surface and yet clear marking of the component is still required.

Another important process in laser material processing is laser engraving. Here, the focused laser beam creates three-dimensional surface structures, which are usually referred to as deep engravings. In this process, material is selectively removed by laser-induced melting and vaporization. The oxidation of the metal on the engraved surface produces metal oxides, better known as rust. This is then easily removed in a second pass with the appropriate parameters. Laser marking can be performed on a wide variety of materials. The correct coordination of the laser source and the material being processed is crucial for feasibility and a good result.
