Fiber laser marking machine carbon dioxide laser marking machine advantages and disadvantages

by:Leadtech Coding     2022-03-28

CO2 laser marking machine is mainly used in non-metal industries, such as craft gifts, wood, clothing, electronic parts, plastics, models, medical packaging, building materials and so on.

The carbon dioxide laser marking machine uses carbon dioxide gas to fill the discharge tube as a medium for generating laser light. When a high voltage is applied to the electrodes, a glow discharge is generated in the discharge tube, which can cause the gas molecules to emit laser light, and the laser energy is amplified. A laser beam for material processing is formed, and the optical path of the laser beam is changed by a computer-controlled galvanometer to realize automatic marking.

Compared with traditional marking technology, the advantages of co2 laser marking machine are that the laser marking is clear, permanent, fast, high output, and pollution-free; graphics , text and serial number can be edited by software, easy to change, and the laser is 30,000 hours maintenance-free, no consumables, low cost of use, energy saving, environmental protection logo, and ROHS standard.

1. The laser of the carbon dioxide laser marking machine is a gas laser with a wavelength of 1064um in the infrared band. It uses RF laser and high-speed galvanometer, so the price of Co2 laser marking machine is higher than that of semiconductor.

2. Carbon dioxide laser marking machines have certain limitations. It cannot mark products made of metallic materials. It is mainly used to mark wood, acrylic, leather and other non-metallic materials.
