Faith UV laser marking machine is developed by using 355nm UV laser, which uses the third-order intracavity frequency doubling technology to compare with the infrared laser, It can reduce the mechanical deformation of materials to a large extent and has little heat effect on processing, because it is mainly used for ultra-fine marking and carving, especially suitable for the marking of food and pharmaceutical packaging materials, microporous marking, high-speed division of glass materials, complex graphic cutting of silicon wafer and other application fields.
