Laser marking is becoming more and more common in life, like marking on beverage bottles, animal ear tags, auto parts QR code marking, 3C electronic marking and so on. Marking color is most common in black, but what many people don't know is that lasers can also mark color patterns.
In 1999, Ann Marie Carey made an initial attempt to laser color marking on the bowl, making laser color marking of metal crafts and jewelry practical.
Laser color marking makes the pattern more diversified. The marked object bids farewell to monochrome, the color layer is enhanced, the image is vivid, and the quality of the product is improved. It is an innovation of traditional craftsmanship. Since then, the application range of laser color marking has been expanding, and it has become a new type of process to increase the added value of products.

The stainless steel material generates a colored oxide on the surface under the action of a laser heat source, or forms a colorless transparent oxide film, which exhibits various colors due to the interference effect of light film. This is the basic principle of stainless steel color marking, simple It is said that under the action of the laser, the surface of the stainless steel has a laser thermal effect, and the laser energy is different, and the stainless steel surface also exhibits different colors.
Conventional stainless steel color preparation methods such as chemical coloring and electrochemical coloring used in the past have high energy consumption, large pollution, and difficulty in achieving fine coloration. In contrast, stainless steel laser color marking has unique advantages.
1. Laser marking is environmental friendly and pollution-free;
2, Fast marking speed, the marking pattern can be permanently retained;
3, Laser marking can edit all kinds of text patterns as you like, easy to operate.
Today, color stainless steel marking is widely used in construction, automotive, arts and craft. Laser color marking provides a new and efficient solution to add a new color to stainless steel products, which is to increase the added value of products.
