The specific color of the laser marking machine depends on the parameters and the material itself, and laser powder is used to match the laser marking machine for color matching. Using some specific materials or marking technology, correctly operating the diode pump to mark the substrate can not only produce a clear and beautiful black and white effect, but also produce a color effect logo.

Like the laser blackening of aluminum, it is difficult for ordinary laser marking machine to realize the laser color marking process of stainless steel. Special laser for color marking is selected, and the pulse width can be adjusted to achieve better color printing effect.

The principle of laser marking machine is to use high-energy laser beam to leak out deep substances through evaporation of surface substances, or to mark traces through chemical and physical changes of surface substances, or to use light energy to burn some substances to mark patterns or characters.

As the most advanced and effective processing method for marking industrial products, laser marking technology has been gradually understood and recognized by various industries, and there are excellent works of laser marking in the fields of food and beverage, medical packaging, electronic components, auto parts, mobile phone parts and so on. In the field of stainless steel marking, a new color marking process has been developed, and it has been matured and developed continuously.

The basic principle of stainless steel color marking is to use high energy density laser heat source to act on stainless steel material, so as to generate colored oxide on its surface or colorless and transparent oxide film, which presents color effect due to the light interference effect of the film. By controlling the laser energy and parameters, oxide layers with different colors and thicknesses can be realized, and even color gradient marking can be realized.
