Marking and labeling of metals

Metals Marking

cleanLASER are particularly powerful systems that deliver outstanding removal results, especially on metals. In addition, thermally generated color changes can be generated.

A speciality of cleanLASER is that the surface can be cleaned, pre-treated and marked in one working step. This not only saves process steps, but also achieves optimum results as well as improved legibility and long-term durability.

If required, we can also provide you with an automation package tailored to the needs of the customer.

special features

    • Particularly powerful laser systems for high marking speeds
    • Efficient ablation marking (depth marking) possible
    • Marking of moving parts (on the fly) for 2D or 3D applications
    • Automation package from a single source

In principle, two methods are used for marking metals

    • Engraving inscription:
      In this process, layers of the metallic surface are specifically evaporated, resulting in ablation and the associated deep engraving.
    • Annealing inscription:
      Especially in the case of steels and stainless steels, the short-time heat of the laser beam achieves a heating above the tempering temperature of the steel. This causes the surface to discolor and a permanent marking without roughening the surface remains visible.
