Both fiber lasers and CO2 lasers are suitable for marking plastics. Based on the desired result and the type of plastic, it is possible to determine which is the best solution. With fiber lasers it is possible to achieve carbonization or color change, obtaining a high-definition contrast marking with perfect legibility, without affecting the surface of the material.

Fiber source lasers are also recommended for removing paint from plastic surfaces. The paint can be removed without affecting the base material, achieving perfect contrast.
Lasers with CO2 source are used for the engraving of the material. By removing the surface layer, a deep marking is obtained, without color contrast.
