UV laser marking machine is a series of laser marking machine, which is developed by 355nm ultraviolet laser. This machine adopts third-order cavity frequency doubling technology. Compared with infrared lasers, 355 UV has a small focal spot, which can greatly reduce the mechanical deformation and processing effects of small hot materials, because it is mainly used for ultra-fine marking and engraving, especially for food and pharmaceutical packaging materials, marking holes , High-speed glass materials and division of wafer complex graphics cutting and other applications. Comparing to other laser machines, the UV laser marking machine have lots of the advantages, let's find out.
