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 355nm 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.

It has following advantages and characters:

1.The machine Using high-performance UV laser (intracavity frequency doubling technology + TEC refrigeration technology), the laser beam quality is superior, bringing users a delicate and beautiful marking effect;

2.Laser beam base film, short pulse width, high peak power, high repetition frequency, small heat affected area, avoid deformation, damage or scorching of the processed material, and high yield;

3. 355nm output wavelength, high photoelectric conversion rate, beautiful engraving effect, good marking effect, good touch feeling, and strong anti-counterfeiting;

4. The marking speed is fast and the efficiency is high; the whole machine has stable performance, small size, low power consumption, and 24-hour continuous and stable operation;
