To meet the specific needs of each application, industrial lasers allow plastic marking with different processes.

In the case of discoloration marking, the laser beam interacts with pigments added from the formulation of plastics. Through photoelectric effect, these pigments will change color, turning more often to black or gray. This allows to mark easily readable and indelible datas, while increasing the speed of the process because of the rapid reaction between beam and pigments.

The ablating method corresponds to evaporation removal of part of an over-layer (paint, anodizing, etc.) covering the part to be marked. To reveal bare portions of the part creates a contrast. This method is particulary interesting for day and night design (location of dashboards buttons regardless of the external light).

The laser engraving technique is useful in cases of non-pigmented plastics. It allows a deeper mark after melting or evaporation of a portion of the material through beam intensity.

Finally, foaming provides a good contrast. It can be implemented on many types of plastics.
