About CO2 Laser Marking

CO₂ laser coding and marking works by directing a focused beam of infrared light onto the surface of a product or packaging, where the energy from the laser heats and alters the material to create a clear, permanent mark. This can involve engraving, etching, or changing the surface colour depending on the substrate.

The laser beam is precisely controlled by mirrors and software to form text, codes or graphics at high speed, with no inks or consumables required, making it a clean and reliable solution for industrial coding.
