Black Uv Laser Marking Machine

Ultraviolet laser marking machine, also known as ultraviolet laser inkjet printer, ultraviolet online laser marking machine, ultraviolet laser laser engraving machine, belongs to the series of fine laser marking machines. The marking principle is similar to that of the fiber laser marking machine. Permanently mark the surface of a variety of materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "engrave" traces through the chemical and physical changes of the surface material caused by light energy, or to burn off part of the material through light energy, showing the required etching. The pattern, text, and content to be marked on the product. It uses a 355 nm ultraviolet laser, which not only has good beam quality (fundamental mode output), but also has a smaller focusing spot (less than 3um in diameter, and the divergence angle is 1/4 of that of the fiber-pumped laser), which can greatly reduce the mechanical properties of the material. Deformation and processing heat effect is minimal, no thermal effect, and no material burning problem, so it is called cold processing, which can realize ultra-fine marking and engraving, and is the preferred product for customers who have higher requirements for marking effect. . It is especially suitable for marking, micro-perforation and surface treatment of materials such as food, pharmaceutical packaging, textiles, and polymer films, high-speed division of glass materials, and complex pattern cutting of silicon wafers.
