The ultraviolet laser marking machine belongs to the series of laser marking machines, but it is developed using a 355nm ultraviolet laser. The machine uses third-order intra-cavity frequency doubling technology to compare with an infrared laser. The 355 ultraviolet light spot is extremely small and can be To a large extent reduce the mechanical deformation of the material and the processing heat effect is small because it is mainly used for ultra-fine marking and engraving, especially suitable for marking food, beverage packaging materials, micro-holes, high-speed division of glass materials and silicon Application areas such as complex wafer cutting of wafers.
Compared with other fiber laser marking machines and carbon dioxide laser marking machines, UV laser marking machines have lower power. The power of the UV laser marking machine is generally 3W, 5W, 10W. The general power of the fiber laser marking machine and carbon dioxide laser marking machine are 10W, 20W, 50W, 100W. Although the UV laser marking machine has a relatively small display power, its function is also relatively powerful. Compared with other marking machines, the UV laser marking machine uses cold light technology, which has good engraving and marking effects for some materials with relatively low melting points. For example jade, plastic, silicone, ceramic, jade, acrylic, etc.
