The most common laser marking effect is black, but what many people don't know is that lasers can also mark color patterns.
In 1999, Ann Marie Carey made a preliminary attempt to laser color marking on niobium bowls, making laser color marking of metal crafts and jewelry feasible.
Laser color marking makes the presentation effect of the pattern more diversified, the color hierarchy is enhanced, the image is lifelike, and the product quality is improved. It is an innovation to the traditional craftsmanship.
Under the action of the laser heat source, the stainless steel produces colored oxides on the surface, or a colorless and transparent oxide film, which exhibits various colors due to the light film interference effect. This is the basic principle of stainless steel color marking, simple In other words, under the action of the laser, the surface of the stainless steel produces a laser thermal effect. The laser energy is different, and the surface of the stainless steel also shows different colors.
Traditional stainless steel color preparation methods such as chemical coloring and electrochemical coloring used in the past have high energy consumption and high pollution. In contrast, stainless steel laser color marking has unique advantages.
1. Laser marking is environmentally friendly and pollution-free;
2. The marking speed is fast, and the marking pattern can be kept permanently;
3. Laser marking can edit various text patterns at will, which is convenient and easy to operate.

Today, when color stainless steel is continuously applied in the fields of construction, automobile, arts and crafts, etc., laser color marking provides people with a brand-new and efficient solution, adding a touch of new color to stainless steel products, but it is a way to increase the added value of products. A good option. In addition to stainless steel, the Riselaser laser marking machine can also print colors on brass.
