With laser engraving copper for example: laser direct copper engraving, the technology has been that is not feasible, but the laser can be directly engraving zinc. By improving the process, implementation of direct laser engraving. First in the copper roll plating a thin layer of nickel, and copper plating on the surface, then coated with a zinc layer. This layer of zinc can absorb laser energy and evaporating, evaporating and its following copper, while generating the ink network points. After carving, like other engraving roller coaster, finally a layer of hard chromium plating on the roller,the prospect of laser engraver for sale is very good.
Direct laser engraving system is mainly composed of 3 parts: the high energy laser, optical transmission system, system, by adjusting the focal length, to adjust the unit area energy
