Why can't the carbon dioxide laser marking machine mark metal materials?

The carbon dioxide laser marking machine uses carbon dioxide gas to be charged into the discharge tube as the medium for generating the laser. After a series of reactions, the gas molecules can release the laser, and the laser energy is amplified to form a laser beam for material processing. Automatic marking is realized by changing the optical path of the laser beam through the computer-controlled galvanometer.

When many friends consult laser marking machine manufacturers about marking machine equipment, the customer service will first ask you what material you are marking on, this is because with the processing Due to the diversification of materials, the models of laser marking machines also extend into many styles. There are relatively suitable marking machines for different materials. Some marking machines are not suitable for marking certain materials, such as CO2 laser marking machines. Not suitable for marking metal, rash purchase will only waste time, energy and cost.

Although there are many CO2 laser marking machines in the market, it is not suitable for every industry. So why can't the carbon dioxide laser marking machine mark metal products? The reason is that it uses the infrared band with a wavelength of 10.6nm, which is limited to processing soft products, and cannot be used for metal products at all, and different wavelengths can be used for different materials.

The CO2 laser marking machine can expand the intelligent and automatic functions of the needs of various application scenarios, and at the same time can improve the special requirements of automatic feeding, camera positioning, intelligent identification, high precision and so on . It is mainly used for marking wood products, plexiglass, metal plates, glass, stone, crystal, Corian, paper, two-color plate, alumina, leather, resin, sprayed metal and other products.
