The laser marking machine can mark the surface of products of different materials, and special laser products can realize stainless steel color marking, aluminum oxide black marking and other processes. The common laser marking machines on the market now include CO2 laser marking machines, fiber laser marking machines and ultraviolet laser marking machines. The main differences between the three laser marking machines are the different lasers, laser wavelengths and application fields. Let's follow the editor to understand the specific differences between CO2, optical fiber, and ultraviolet laser marking machines.

The differences between optical fiber, carbon dioxide and UV laser marking machines are as follows:

1.Different Lasers:

Fiber laser marking machines use fiber lasers, carbon dioxide laser marking machines use CO2 gas lasers, and ultraviolet laser marking machines use short-wavelength ultraviolet lasers.

UV laser is a very different technology from CO2 and fiber laser technology, UV laser is also known as blue laser beam, this technology has low heat engraving ability, it does not heat the material like fiber and CO2 laser marking machines The surface belongs to cold light engraving.

2.Different Laser wavelengths:

The laser wavelength of the fiber laser marking machine is 1064nm, the laser wavelength of the carbon dioxide laser marking machine is 10.64μm, and the laser wavelength of the ultraviolet laser marking machine is 355nm.

3.Different fields of application:

CO2 laser marking machine is suitable for engraving most non-metallic materials and some metal products. Fiber laser marking machine is suitable for engraving most metal materials and some non-metallic materials. UV laser marking machine can clearly mark all heat-sensitive materials. Adverse reactions to plastics and other materials.

Marking features and applications of CO2, optical fiber, and ultraviolet laser marking machines:

1. CO2 laser marking machine
