Difference between fiber Laser marking machine and CO2 Laser marking machine

First of all, we need to know the difference between fiber Laser marking machine and carbon dioxide Laser marking machine, which mainly depends on the different lasers of the two machines, the different beams they emit and the different processing range.

The fiber laser used in fiber Laser marking machine refers to the laser with rare earth doped glass fiber as gain medium. The generated beam is 1064 nm. The advantages of fiber laser are: low cost, mature technology, miniaturization and intensive advantages of glass fiber, and the advantages of no adjustment, no maintenance and high stability, which are unmatched by traditional laser. Fiber laser is competent for harsh working environment and has high tolerance for dust, vibration, impact, humidity and temperature. No thermoelectric refrigeration and water cooling, only simple air cooling, can greatly reduce the cost. High electro-optic efficiency: the comprehensive electro-optic efficiency is as high as 20%, greatly saving power consumption and operating cost. Can process metal and part of non-metallic materials.


CO2 Laser marking machine uses CO2 gas as the laser medium to emit laser, and the wavelength of the gas laser is the core configuration of the equipment. It mainly targets at the marking of non-metallic materials, such as plastic, glass, etc., but after a period of use, it needs to be inflated (CO2 gas). The lifetime of the laser is about 30000 hours. It can work continuously for a long time. It is the first choice for marking of non-metallic materials because of the combination of the laser and the flight marking.

From the processing application point of view, fiber Laser marking machine and CO2 Laser marking machine beam wavelength density and length is not the same. CO2 Laser marking machine is micron, application range: PVC, ABS, PMMA, PC, AK, EP, glass, wood, paper, etc.


The optical fiber Laser marking machine is 1064 nm, which is much shorter than CO2 laser, and has better absorption of metal. Scope of application: all kinds of metal and part of nonmetal, electronic separation components, integrated circuits (IC), electrical circuits, mobile communication, hardware products, knives and kitchenware, tool accessories, precision instruments, glasses and clocks, computer keyboard, jewelry, auto accessories, plastic buttons, plumbing accessories, sanitary ware, PVC pipes, medical devices, packaging bottles and cans, etc. Fiber Laser marking machine and CO2 Laser marking machine have different application scope, both of them have irreplaceable place, but fiber Laser marking machine is more widely used than CO2 Laser marking machine.


In terms of service life, the service life of fiber Laser marking machine is 100000 hours, and that of CO2 marking machine is 30000 hours. The former is much longer than the latter.


In terms of accuracy, optical fiber is a nano scale processing method, while CO2 is a micron scale, so the accuracy of optical fiber is higher than CO2.


In a word, who has more advantages? Fiber Laser marking machine is certainly much more than CO2 Laser marking machine, but both have irreplaceable aspects.
