Laser marking is becoming more and more common in life, beverage bottles, animal ear tags, auto parts QR code marking, 3C electronic marking and so on. Marking 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 at laser color marking on the bowl, making laser color marking of metal crafts and jewelry practical.
Laser color marking makes the appearance of the pattern more diversified. The marked object bids farewell to the monochromatic color, the color layer is enhanced, the image is vivid, and the quality of the product is improved. It is an innovation of the traditional craft. 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 and transparent oxide film, which presents 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 environmentally friendly and pollution-free;
2,The marking speed is fast, the marking pattern can be permanently retained;
3, Laser marking can edit all kinds of text patterns as you like, convenient and easy to operate.
