laser colour marking priciple

Dear friend, do you know? For stainless steel products, the Chanxan color laser marking machine can add the color of the marking pattern, and can edit various text patterns as desired. It can greatly increase the added value of stainless steel products, enhance the market competitiveness of stainless steel products, and enhance the brand image of enterprises. Below, Chanxan Laser leads you to understand the popular stainless steel coloring on the market.

MOPA laser marking stainless steel changes before and after processing is nothing more than three ways: one is to generate colored oxides; the other is to form a very thin colorless transparent oxide film on the surface of stainless steel under the action of chemical, electrochemical or laser The oxide film produces an interference effect and shows color on the stainless steel surface; the third is the simultaneous generation of colored oxide and colorless oxide film.

Application note

Principle of laser marking color development: 1. Generate colored oxides; 2. Generate colorless transparent oxide films, generate interference and show color; 3. Simultaneously generate colored oxides and colorless oxide films.

Process analysis

At dense filling pitches, small and medium pulse widths, and high frequencies, color changes are mainly affected by frequency and power. The differences in these colors are mainly affected by the energy of the laser's single pulse and the rate of spot overlap on the material.
