3W UV laser marking machine

　　The 3W UV laser marking machine belongs to the series of laser marking machines. Therefore, the principle is the same as that of the laser marking machine. The laser beam is used to mark the surface of various materials with permanent marks. The effect of marking is to expose deep substances through the issuance of surface substances, or to "cut" traces by chemical or physical changes of surface substances by light energy or to burn some substances by light energy, showing the desired etching pattern. , text. However, it is developed using a 355nm UV laser. The machine uses a third-order intracavity frequency doubling technique compared with an infrared laser. The 355 UV focused spot is extremely small, which can greatly reduce the mechanical deformation of the material and has a small thermal influence on processing. Because it is mainly used for ultra-fine marking and engraving, it is especially suitable for applications such as marking of food, medical packaging materials, micro-holes, high-speed division of glass materials, and complex graphic cutting of wafer wafers.

UV laser marking machine product advantages

　　Due to the extremely small focus of the UV laser and the small heat affected zone, the UV laser marking machine can perform ultra-fine marking and special material marking. It is a recommended product for customers who have higher requirements for marking. UV lasers are suitable for processing materials other than copper. Not only the beam quality is good, but also the focused spot is smaller. The application range of ultra-fine marking is wider; the heat-affected zone is extremely small, no thermal effect is generated, and material burning problem does not occur; the marking speed is fast and the efficiency is high; the performance of the whole machine is stable. Small size, low power consumption and other advantages.

3W UV laser marking machine application industry

　　Ultraviolet laser marking machine is mainly based on its unique low-power laser beam. It is especially suitable for the high-end market of ultra-fine processing. The surface of packaging bottles for cosmetics, medicines, jewelry and other polymer materials is marked with fine results and clear marks. Ink printing and no pollution; flexible pcb board marking, dicing; silicon wafer micro-hole, blind hole processing; LCD liquid crystal glass two-dimensional code marking, glass surface punching, metal surface plating marking, plastic Laser marking of buttons, electronic components, gifts, communication equipment, building materials, etc.
