Laser Marking Machine Marking Coloring in Stainless Steel Vicky
Stainless steel material is widely used in various fields. Such as construction, kitchen appliance, electronic equipment, vehicles and so on. Because of its corrosion resistance and processability.
People have developed a variety of processing technic for using stainless steel processing. Such as grinding, sandblasting, corrosion and so on. Stainless steel has a silver-white metallic luster. We generally use fixed color paint to spray the surface to make Stainless steel have more color in practical application.
For stainless steel surface coloring, it can divide into chemical coloring method. Electrochemical coloring method.
With the enhancement of environmental awareness, awareness of green processing is growing as well. Traditional spraying technology has been unable to adapt to the needs of the market. Meanwhile, because of the environment, the paint sprayed on the surface of stainless steel may fall off . Because of corrosion and affect the normal use.
The principle of stainless steel material color laser marking is using thin-film analyzer to analyze the stainless-steel laser painted surface. that a thin-film will produce on the surface of stainless steel under the action of laser. Because when light hits the surface of the film after the laser action shown in the figure below. What kind of light strengthened when it interferes depends on the thickness of the stainless steel oxide film. When the light of one of the colors intensified, the surface of the thin film shows the enhanced color.
At present, the laser marking application in China has been used by increasingly manufacturers. Farewell general laser marking only black, white, and grey, based on the expansion of the field of stainless steel marking, a new process of stainless color marking appeared. Only a few minutes, the stainless-steel surface can have a variety of beautiful patterns, not only improve the aesthetic value, but also provides more possibilities for the application of stainless steel in life, and create another era of laser marking.
