TruMark Station 7000

Local heat input is used to discolour the workpiece surface. The annealing colour changes depending on the material and the energy input. The surface stays smooth, which means that dirt cannot be deposited.

During engraving, the laser beam removes part of the base material, thus creating a depression. This may have steep or beveled edges.

If the material and laser wavelength are optimally matched, the dye molecules are deliberately discoloured or faded. The surface remains smooth. In addition to metallic materials, organic substances such as wood or leather can also be processed with the TRUMPF marking lasers.

The laser can be used to structure surfaces for a specific function or to clean them. Rust, oil or phosphate layers may be removed in preparation for subsequent processes.

The laser can be used to structure surfaces for a specific function. If the surface is structured with tiny melt elevations, significantly higher adhesion effects can be achieved with the same material properties. If interlocking components are structured after the addition of micro-depressions, the running characteristics improve significantly with the same quantity of lubricant.

Ablation partially removes thin top layers of multi-layer plastics which are applied to the basic material and have very different colours. This process can be used for the day and night design, for example, which is used in the automotive and other industries.

During foaming, the laser heats the plastic to cause a short melting process. During the subsequent cooling process, small gas bubbles become trapped and diffuse the light that falls on them and is reflected. This type of laser marking produces a raised marking.
