Advantages and disadvantages of CO2 laser marking machine

The co2 Laser marking machine uses carbon dioxide gas to charge the discharge tube as a medium for generating laser light. When the high voltage is applied to the electrodes, the glow discharge is generated in the discharge tube, the gas molecules can release the laser light. And after the laser energy is amplified, the laser beam is formed for processing the material, the laser beam path is changed by a computer controlled galvanometer to implement automatic marking.

Co2 laser marking machine is mainly used in non-metal industries such as craft gifts, wood, clothing, greeting cards, electronic components, plastics, moulds, medical packaging, architectural ceramics, fabric cutting. The marking of the inkjet printing method not only is easy to erase, but also contains toxic substances and pollutes the environment.

Advantages of the CO2 laser marking machine:
Compared with the traditional marking technology, the co2 laser marking machine has the advantages of clear and permanent laser marking, fast speed, high yield and no pollution. The graphics, text and serial numbers can be edited by software, the change is convenient, and the laser has 30000 hours of maintenance-free, no consumables, low cost of use, energy saving, environmentally friendly.
Disadvantages of the CO2 laser marking machine:
1. The laser of the co2 laser marking machine is a gas laser with a wavelength of 1064um in the infrared light band. And the RF laser and the high-speed galvanometer are used, therefore, the price of co2 laser marking machine is higher.
2. CO2 laser marking machine has certain limitations, it can not mark metal products, mostly used for wood, acrylic, leather and other non-metal marking.

The Co2 laser marking machine of Shenzhen Sun Laser exposes deep substances through the evaporation of surface substances, thus engraving exquisite patterns, trademarks, dates, logos or characters, with fast processing speed, even processing quality, long service life and high conversion efficiency.
