The common marking color of laser marking equipment is black or gray. In fact, the laser can also mark the color pattern on the metal surface. In just a few seconds, it can add a bright color to the rigid metal, full of childlike cartoon patterns and exquisite Roses, colorful butterflies... everything.

The basic principle of stainless steel color marking is to use a high energy density laser heat source to act on the stainless steel material to form a colored oxide on the surface, or to form a colorless transparent oxide film, which is presented by the optical interference effect of the film. Colored effect. Moreover, by controlling the laser energy and parameters, different colors exhibited by different thickness oxide layers are realized, and even color gradient marking is realized.
