Laser marking on the plastic, or plastic engraving, is a process during which components are labelled or marked with the aid of a laser. The polymer that the plastic parts are made of dictates the methods used and also the energy input needed to laser the plastic. The result of the laser marking depends, to a significant extent, on the type of plastic, additives such as dyes and the type of laser.
Laser marking is a non-contact optical process in which the plastic has to absorb the laser beam. This behaviour is also used in the laser welding of plastics, during which one welding partner absorbs the laser beam and the other welding partner is transparent for the laser beam.
