Jinan large laser engraving machine work done by laser processing means, between the workpiece and no machining force, with no contact, no cutting force, the advantages of small heat-affected to ensure the accuracy of the original artifact. Meanwhile, wide adaptability of the material can be produced on the surface of a variety of materials and a very fine marker very good durability, controllability and the time controllability of laser space well, the processing of the object material, shape, size processing environment and freedom are great, especially for automated processing and special surface processing. And flexible processing methods, can meet the needs of both the individual laboratory-style design, but also to meet the requirements of industrial mass production. The main carving materials: wood, plexiglass, metal plates, glass, stone, crystal, Corian, paper, color plates, aluminum, leather, plastics, epoxy resin, polyester resin, spray metal. Used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware, tools, accessories, precision instruments, eyeglasses and clocks, jewelry, auto parts, plastic buttons, building materials, PVC pipe, medical equipment and other industries.
