Why Can Laser Marking Machine Mark Color on Stainless Steel?

in Blog, ,

The laser marking machine market has developed very steadily, the technology has become increasingly mature, and its application in the industrial market has become universal. Laser marking machines have developed a color marking effect in the stainless steel industry.

The difference between the pictures and texts marked by color laser marking machine and traditional ink or color powder and film machine is that the laser marking machine uses a high-energy laser beam to irradiate the surface of the metal, so that it produces physical changes to create various colors.

Why does stainless steel show color after being marked by a laser marking machine?

There are three ways:

One is to generate colored oxides.

Two is by chemical, electrochemical or laser action, in the stainless steel surface to generate a very thin layer of colorless transparent oxide film, with interference effect to show color.

Three is the presence of both colored oxide and oxide film of a mixed state.

The laser energy of the laser marking machine corresponds to the color change of the stainless steel. Stainless steel produces thermal effects under the irradiation of lasers. With the addition or subtraction of laser energy, the surface of stainless steel can produce various color changes.

Laser marking machine is a combination of computer and machinery, which is simple and convenient to operate. The laser marking machine is controlled by computer, and the graphics and text can be changed and edited at will in the marking software without changing the mold, and it is environmentally friendly, pollution-free, noise-free, fast marking, no consumables.

The use of color laser marking machine in the stainless steel processing industry can make the product more colorful and improve the ornamental value of the product. Moreover, the pictures and texts produced by laser marker are smooth, exquisite and beautiful, and there is no sense of violation, which makes the products look high-end. Linxuan online flying color laser marking machine can also realize assembly line production, which can greatly increase the production efficiency of enterprises and reduce various costs.
