UV Laser Marking Machine Principle And Advantages

UV laser marking machine belongs to the series of laser marking machines, but it is developed with 355nm UV laser. The machine adopts the third-order intracavity frequency doubling technology. Compared with infrared laser, the 355 UV light focus spot is extremely small, which can greatly reduce the mechanical deformation of the material and has little processing heat effect. Because it is mainly used for ultra-fine marking and engraving, it is particularly suitable for marking food and pharmaceutical packaging materials, drilling micropores, high-speed division of glass materials, and complex graphic cutting of silicon wafers.
Principle
The UV laser marking machine is a series of laser marking machines, so the principle is similar to that of the laser marking machine, which uses a laser beam to mark the surface of various materials permanently. The effect of marking is to directly break the molecular chain of the material through a short-wavelength laser (different from the evaporation of the surface material produced by the long-wave laser to expose the deep material) to show the required etching pattern and text.
Advantages
Due to the extremely small focus spot and small processing heat-affected zone, UV laser can be used for ultra-fine marking and special material marking. It is the preferred product for customers with higher requirements for marking effect. In addition to copper, UV lasers are suitable for processing a wider range of materials. Not only does it have good beam quality and a smaller focused spot, it can achieve ultra-fine marking; it has a wider range of applications; the heat-affected zone is extremely small, so there will be no thermal effect or material burning; it has fast marking speed and high efficiency; the whole machine has stable performance, small size, and low power consumption.
