Laser printer is a perfect combination of high-speed laser marking equipment and full-automatic feeding system, with flexible matching, which can quickly connect and promote the benign interaction and improvement between production processes; optional CO2 laser, optional fiber laser, UV laser, etc., to meet the marking need of customers for different materials. Enterprises with conditions can establish " traceability system " of their own products, so as to strengthen the production management of enterprises to better meet the needs of the market. UV laser marking machine belongs to the laser marking machine series products, but its use 355 nm laser source do research and development, and it uses of third-order intracavity frequency doubling technique, compared to the infrared laser, 355 uv laser is focused on the spot is very small, can largely reduce the material and processing of mechanical deformation heat effect is small, because it is mainly used for super fine marking, engraving, especially suitable for in food, medicine, package marking, microporous, glass material of high speed divided and complex graphics on silicon wafer cutting and application field.
