The basic principle of stainless steel Color Laser Marking Machine is to use the high energy density laser heat source to act on the stainless steel material, to make its surface generate colored oxide, or to generate a layer of colorless and transparent oxide film, because of the light interference effect of the film, it presents the color effect. In addition, by controlling the laser energy and parameters, different colors of different thickness oxide layers can be achieved, and even color gradient marking can be achieved.
Color laser marking technology can mark numbers, bar codes, two-dimensional codes, patterns and other information on stainless steel to meet product traceability or aesthetic requirements. Under the action of laser, colorful stainless steel can be used in tableware, automobile, architecture, arts and crafts and other fields. For example, using laser color marking technology to depict exquisite color patterns on the surface of stainless steel spoon chopsticks gives people a creative and novel feeling. The product has been sold on the Internet.
