The principle of laser marking technology is the high energy laser beam irradiates the surface of the workpiece, the moment produced two-dimensional code, non-contact processing, impact on the workpiece, the two-dimensional code label has irreversible effects, has a permanent characteristic.
Laser marking machine mainly include laser device, galvanometer, software and cabinet .Different materials choose different laser device.
Infrared fiber nanosecond laser (1064nm)
Two-dimensional code marking on metal products mainly using infrared fiber laser, including stainless steel, steel, cast iron and so on.
Infrared CO2 nanosecond laser (10640/935nm)
Leather, cloth, PCB are mainly used CO2 laser. According to the characteristics of the material industry, this type are divided into 10640nm and 935nm infrared CO2 laser.
Ultraviolet nanosecond laser (355nm)
It mainly uses ultraviolet laser on some transparent materials, such as glass, PET, protective film, PVC.
Green nanosecond laser (532nm)
The glass in the two-dimensional code is the use of the green laser, and green laser marking is not very extensive on the effect and cost at present market.
