The development of the domestic laser marking technology, has been from the start of the high speed development in the steady development stage now, also more widely application in domestic industries. At this time, in order to meet the many needs of the market, enterprises start to look for more advanced marking technology. Then, in the field of stainless steel marking, the stainless steel color marking this new technology, created another era of laser marking.

before understanding stainless steel color marking, we need to understand the principle of stainless steel color. There are three color ways: one is to generate colored oxide; 2 it is chemical, electrochemical, or under the action of laser in the stainless steel surface to generate a very thin layer of colorless transparent oxide film, the oxide film interference effect, can be on the table and show the color; Three is exist nonferrous metal oxide and a mixed state of oxide film.



so, in a nutshell, is under the action of laser, laser heat effect occurs on the surface of stainless steel. Using high energy, high density of laser beam on the surface of the workpiece local irradiation, make rapid gasification surface material or color changes, so as to reveal the deep substance; Or the result of the surface material chemical physical change and portrays the mark; Or through light burned part material, show the etching of the graphics and text.

by laser heating effect, it is concluded that the laser energy density and the thickness of thin film is proportional to the relationship. With laser power increasing, the color of the stainless steel surface in accordance with the following color sequence change: orange - Red - Purple - Blue - Green and blue - Blue and green - Green - Yellow and green - Yellow - Orange - Red.

due to the advancement of laser, the stainless steel color marking believe that will soon be able to replace traditional color ink/film printing process. Because, color laser marking machine, it with ink deposition technology and those by applying color powder or thin film technology, advanced laser can make the color of the material to change its physical effect, and the polymer pyrolysis reaction in oxygen environment, so in the metal surface marking materials can produce a variety of colors.



'tools/raw material

stainless steel materials, laser equipment, adjustment, ruler, adjustable workbench etc.

low method/procedure

first of all, the material is a piece of thickness can't be too thin stainless steel products. （ Too thin, easy to deformation, heated remember) Second, after adjust focus, slightly under partial coke, abort the first layer on the surface of the stainless steel

again, repeatedly marking, lower or upper at the same time, look at the color change timely adjust height. （ Dark red, green, etc. )

in the end, when you want to color up later, the focus can be reset.

* note

1, the side marking, adjust the height, see the color of progressive change at the same time, be sure to keep in mind the

2, parameters to adjust in

edit any graphics and text follow one's inclinationsly, very convenient and easy to operate, less environmental pollution, fast printing & hellip; … For stainless steel products industry, stainless steel color laser marking can add graphic colorful, can be a sharp surface of stainless steel products, value-added products to enhance the laser in stainless steel products market competitiveness of enterprises.

so exquisite stainless steel color laser marking technology, have impressive to you? As the pioneer of metal manufacturing in laser processing equipment, laser equipment factory also keep up with the development of science and technology, China's metal laser marking machine, fiber laser marking machine can also satisfy the users, such as stainless steel, aluminum and other metal color printing or deep carved. Fashion, lovely, high-grade, both delicate and lovely cartoon design, or a variety of digital, decorative pattern, logo, and even beautiful portraits, laser laser equipment factory in China also can help you to leave the most real memories.
