Serial number marking, on-the-fly marking; fixed laser marking design, simple operation, perfect upper and lower ventilation system, environmental protection and safety; suitable for all kinds of leather, leather, two-color board, plastic and various solid materials.
Difference 3:
From the working principle:
CO2 laser marking machine uses infrared light band, 10.64μm gas laser, CO2 gas is charged into the high-voltage discharge tube to generate glow discharge, so that gas molecules release laser, and the laser energy is amplified to form a laser beam for material processing , The laser beam vaporizes the surface of the processed body to achieve the purpose of engraving.
The above is the difference between the two, but the bigger point is the lasers of the two. One uses a fiber laser and the other uses a gas laser.

The difference between fiber laser marking and co2 marking machine is as follows:
Fiber laser marking machine: Fiber laser has been a hot spot in laser research in recent years. It is unanimously considered as a new generation product that may completely replace solid-state lasers. Fiber laser refers to a laser that uses rare-earth-doped glass fiber as the gain medium. Fiber laser can be developed on the basis of fiber amplifier: high power density is easily formed in the fiber under the action of pump light, resulting in laser working material. The energy level “number inversion” can form laser oscillation output when a positive feedback loop (to form a resonant cavity) is properly added. Fiber laser marking machine uses laser beam to make permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to “carve” traces through the physical changes of the surface material caused by light energy, or to burn off part of the material through light energy to reveal the pattern to be etched , Text, bar code and other graphics.

Optical fiber marking machine is suitable for all metal materials and plastic rubber, spraying materials, electrical materials, etc.
Carbon dioxide marking machine is suitable for non-metallic materials such as leather, cloth, paper, bamboo and wood products, acrylic, glass, resin, etc.
The performance of lasers and products are different. If you buy equipment, you must choose according to your product marking needs!
In the industry, the two models are currently compared. They are optical fiber marking and CO2 laser marking machines. Laser marking machines are also called laser engraving machines, laser coding machines, and laser engraving machines, but many people don’t know them well. The difference between fiber laser marking machine and co2 laser marking machine, Shanghai Yixi laser marking machine. They are mainly different in machine principle, performance, application industry and materials.
