Color fiber laser marking stainless steel, making life colorful

2020-08-12 15:35:49

Stainless steel is closely related to our lives. Stainless steel used in daily life such as thermos cups, tableware, knives, etc. has always been an item that people cannot live without.

As a hardware material, stainless steel can not only be used for interior decoration, but also can be made into various daily necessities, and it has been loved by the majority of families. Compared with this, it is important that stainless steel products are wear-resistant, durable, and easy to care for, so they are even more popular.

The color of stainless steel we see is usually white or silver, so are there other colors for stainless steel?  The answer is yes, there are other colors for stainless steel, in addition to white and silver, stainless steel also has bronze, copper, coffee, and rose Various colors such as gold. 

With the development of science and technology, the technology of fiber laser marking machines is becoming more and more mature. Technicians can use pulse laser and computer-aided design to "dye" stainless steel with beautiful colors. Before coloring, first immerse the stainless steel in a nitric acid solution, and then use pulse technology to illuminate the stainless steel with a pulsed laser. Because of the different exposure time, different colors will appear on the stainless steel. Through this technology, you can easily The stainless steel is "dyed" with several colors such as blue, green and golden yellow.  The reason why the laser changes the color of stainless steel is related to the ingredients of the stainless steel. After receiving laser irradiation, the chromium content in stainless steel will increase, and the color of the oxide film will be different if the chromium content is different. There are many colors colored using pulse technology, including more than 10 beautiful colors such as bronze, copper, rose gold.

Carmnhaas is a professional laser equipment supplier in China(Fiber laser marking machine manufacturer), providing you with laser technical support to realize different colors of stainless steel. In just a few minutes, the stainless steel surface can have various beautiful patterns, which not only improves the aesthetic value, but also provides more possibilities for the application of stainless steel in life.

(1) The pulse width is adjustable, and different colors can be obtained on stainless steel;
(2) Green processing, compared with spray paint, laser marking is pollution-free;
(3) Non-contact processing, no product damage, no tool wear, and good marking quality.
(4) The laser beam is thin, the processing material consumption is small, and the processing heat-affected area is small.
(5) High processing efficiency, convenient computer control and high degree of automation.
