Carbon dioxide marking machine

Principle of CO₂ Laser Marking Machine

The CO2 laser is a type of gas laser that produces a wavelength of 10.6 μm, which falls within the mid-infrared frequency range. CO2 lasers offer relatively high power and high electro-optical conversion efficiency, making them the most powerful type of laser currently available. The CO2 laser uses CO2 gas as the working medium. CO₂ and other auxiliary gases are filled into the discharge tube. When a high voltage is applied to the electrodes, a glow discharge is generated in the discharge tube, causing the gas molecules to release laser energy. After amplifying the released laser energy, laser processing can be performed.

Advantages of CO₂ Laser Marking Machine

With a wavelength of 10.64 μm, it is easily absorbed by most non-metallic materials. It has high electro-optical conversion efficiency, and the laser output mode is primarily the fundamental mode, ensuring good and stable beam quality. It is a non-contact processing method, free from mechanical wear and deformation, requires no consumables, has low processing costs, and high processing efficiency, with processing speeds measured in milliseconds. It offers flexible control, is compatible with automated production lines, provides fast marking speeds, allows for easy changes to marks, and requires no molds.

Application Industries of CO₂ Laser Marking Machine:

The CO2 laser marking machine offers high engraving precision, fast speed, and stable performance. It can quickly engrave intricate patterns on non-metallic materials, with clear and wear-resistant marks. The engraving depth can be adjusted as desired, and no consumables are required during the process. It is widely used in industries such as eyewear, buttons, leather, fabrics, ceramics, glass, crystal, rubber, bamboo, and wood products.
