Color Laser Marking Machine Metal

Color Laser Marking Machine Metal,The difference between the image and text marked by laser color and the traditional ink or color powder or film is that the laser marking machine irradia​tes the metal surface with high-energy laser beam, so as to produce physical changes and various colors. Why does stainless steel display colors? There are three ways to develop color: one is to generate colored oxide; the other is to generate a very thin layer of colorless and transparent oxide film on the surface of stainless steel under the action of chemistry, electrochemistry or laser. If the oxide film has interference effect, it can show color on the surface; the third is to have a mixed state of colored oxide and oxide film at the same time.
