Which Type of Laser Marking Machine Should I Select?

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.

Two - Dimensional Code Laser Marking Machine

For some very high accuracy requirements of two-dimensional code can also use picosecond laser, such as the two-dimensional code that our eyes can not see with the 0.12x0.12mm size, usually need a magnifying glass.

Every material is not fixed with only one kind of light to do, such as metal materials can use both CO2 and UV laser marking machine. But the infrared fiber laser price is more cheaper, faster, better. So that the two-dimensional code laser marking need to select the appropriate light source to do.
