During structuring, the laser creates regularly arranged geometries in the layer or in the base material, so that the technical characteristics are changed in a targeted manner and a new functionality is developed. One example: scoring or applying small (oil) depressions for defined sliding properties. The individual elements in such structures often measure only a few micrometers. Short laser pulses with very high pulse power generate such high energy densities that the material usually evaporates immediately (sublimation). Each laser pulse produces a small depression, melt is predominately prevented.
Certain properties are generated by laser structuring which, for example, have an effect on the friction characteristics or electric and thermal conductivity. In addition, laser structuring increases the adhesive strength and longevity of the workpiece.
No additional blasting agents or chemical substances which would prove elaborate and expensive are needed for structuring surfaces.
The laser achieves controlled structures, precise down to the micrometer and which are very easy to reproduce.
Compared to mechanical tools which can wear out quickly, the laser is non-contact and therefore absolutely wear-free.
No melt or other processing residue is left on the component with laser processing.
Regularly arranged geometries are generated in surfaces in a reproducible way using laser radiation (usually pulsed). The laser beam melts the material in a controlled manner and solidifies into a defined structure thanks to appropriate process management.
Specialist for large surfaces
We offer you a wide range of marking lasers in an array of power classes and with all common wavelengths (infrared, green, ultraviolet).
Our pulsed TRUMPF TruPulse nano fiber lasers with GTWave and PulseTune technology are some of the most versatile industrial lasers in the TRUMPF portfolio.
