UV laser marking machine belongs to the series of laser marking machine, but it uses 355nm ultraviolet laser developed from, the machine compared with infrared laser, 355 ultraviolet light focus spot is extremely small, can largely reduce the mechanical deformation of the material and processing heat impact is small, because mainly used for ultra-fine marking, engraving, especially suitable for food, pharmaceutical packaging materials marking, punching micro-hole, high-speed division of glass materials and complex graphics cutting of silicon wafers and other applications.
