Stainless Steel (Stainless Steel) is the abbreviation of stainless and acid-resistant steel. It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, no heat treatment hardening, chemical phenomenon, and non-magnetic properties. , The use is very wide.

In the processing and manufacturing process of stainless steel products, in order to meet some specific requirements, it is often necessary to make some logos or engrave some pictures and texts on the stainless steel products, and some specify to be marked in black. With the maturity of laser marking technology in recent years With the development of society, many companies have adopted high-tech products that integrate laser technology, optical technology, precision machinery, electronic technology, computer software technology, and refrigeration. Laser marking machines mark stainless steel products. Why does laser marking Is the labeling machine more and more popular with production and processing enterprises? You can refer to "Laser Marking Machine (Laser Engraving Machine) Knowledge Summary" 

Below, Foshan Fulan Laser will briefly describe for everyone: the method of laser marking machine black on stainless steel (that is, the black effect on the surface of stainless steel):

The stainless steel marking uses a fiber laser marking machine. The laser power of the fiber laser marking machine produced by Foshan Fulan Laser has 10W, 20W, 30W, 50W, and the stainless steel black must be at least 20W or more:

1. Adjust the power of the laser to 20;

2. Adjust the marking speed to 400mm/S;

4. The off-focus method is adopted, and the density is 2-3 mm away from the focus;

5. Adjust the line spacing to 0.03;

6. Adjust the frequency to 50.

The above is only one of the tuning parameters for stainless steel blackening. Because the purity of the material is different, the parameters will be different. The color depth is related to the marking speed, frequency, current size, density, and laser power. Once in place, the effect will be completely different. Moreover, not all stainless steel workpieces can produce a pure black effect. The specific requirements depend on the purity of the material. The same material, with different purity, will have different laser marking effects.
