Stainless steel belongs to metal. Marking and engraving on metal can be done by conventional solid-state laser marking machines, such as fiber laser marking machines and semiconductor laser marking machines. But the carbon dioxide laser marking machine can't do it. It can only process non-metallic materials, such as bamboo, wood, leather, cloth, and plastic.

In recent years, with the rapid development of laser marking technology, equipment is constantly being upgraded. Semiconductor laser marking machines have been gradually eliminated. Now almost all fiber laser marking machines are used for engraving on metal materials. So, what is What about fiber marking machine?

The so-called fiber laser marking machine is that it uses a fiber laser, which can be developed on the basis of a fiber amplifier: high power density is easily formed in the fiber under the action of the pump light, resulting in the laser energy level of the laser working material The "population number inversion" can form a laser oscillation output when a positive feedback loop (forming a resonant cavity) is properly added.

Applicable materials for fiber laser marking machine: Mainly used for processing various metals and some non-metallic materials with high ignition point, especially for marking high hardness, high melting point, and brittle materials.

Features of fiber laser marking machine:

1. Long life: The life of fiber lasers is more than twice that of other types of lasers, and the average lifespan can reach about 100,000 hours.

2. Wide range of application: laser processing can be performed on a variety of metal and non-metal materials, especially for marking high hardness, high melting point, and brittle materials.　　

3. Cooled by air cooling, the whole machine is compact;

4. Power saving: the current required for marking is smaller than other types of laser marking machines;

5. High reliability and good stability: The fiber laser marking machine has many unique advantages in laser marking applications, which greatly guarantees the reliability of the system. At the same time, the laser is excited in the fiber waveguide to increase the oscillation, so the loss is small , Good stability, not affected by external dust vapor and mechanical vibration, the output laser beam is stable;

6. Fiber laser equipment can also be used normally in certain harsh environments, such as shock, vibration, high temperature or dust.　　

7. Fiber laser marking machine has low consumption, minimal impact on the environment, no pollution, and simpler operation.

The fiber laser marking machines produced by Foshan Fulan Laser all use high-speed digital scanning heads, and the marking speed is 2-3 times that of traditional models; the beam quality is good, close to the diffraction limit, which can achieve more precise marking; The electro-optical conversion rate is as high as 30%, and the power consumption is about 10% of that of traditional models; it adopts computer control, high processing efficiency, and easy to realize automation.　

The laser marking machine series produced by Foshan Fulan Laser Technology Co., Ltd. are classified according to lasers. There are mainly 5 types: optical fiber, green light, ultraviolet, carbon dioxide and mopa. Among these five types of laser marking machines, fiber laser marking The price is the lowest. As for why it is cheaper than other types of laser marking machines, it is nothing more than its cost lower than other types.
