Kunststoff laserbeschriften
The wide variety of different plastics makes high demands on the selection of the most suitable laser method.
Das Laserbeschriften von Kunststoffen erfolgt durch Karbonisieren oder Aufschäumen.
When carbonization occurs, a dark color envelope is made, while the frothing produces a bright mark.
In series production, it may be useful to add additives to the plastic to increase the contrast.
Other methods are the selective removal of a surface layer (varnish) to make the underlying material visible or the engraving of the workpiece.
