UV laser marking machine is a laser equipment that can mark metals and non-metals at high speed. Different from fiber and CO2 laser marking machines, UV laser marking can be used for ultra-fine marking, such as 1mm text. For marking materials, although UV laser marking machine can mark metal, fiber laser marking can provide better metal marking effect and lower price. Therefore, UV laser marking machine is mainly used to mark non-metals, especially glass.

UV laser marking machine is designed and manufactured with a 355nm laser. The 355nm uv laser has a very small focus and there is almost no thermal effect in processing, so it is also called “cold marking”. The shorter the wavelength of the laser, the smaller the laser spot and the higher the accuracy, and the smaller the heat-affected zone formed during processing, so UV laser marking machine can be applied to ultra-fine marking and engraving.
