The powerful function of the laser marking machine is that it stands in many industries and has obtained a wide range of applications and rapid development. It has a large basic advantage. In addition to the marking quality and marking speed, there are many processes that traditional marking methods cannot reach, such as Marking color.

Color laser marking machine is different from ink deposition technology and those using colored powder or film technology. More advanced laser can change the color of plastic. This typical physical effect is related to the thermal decomposition reaction of polymer in oxygen In contrast, various colors can be produced on the surface of metal raw materials, and the durability is very good.

The specific color of the laser marking machine depends on the parameters and the material itself. Some specific materials or marking processes are used. White and black marking are often used. However, some materials can produce very beautiful colors, such as acting on stainless steel, can also produce colorful colors, in the endless application of colored stainless steel in the fields of architecture, automotive, arts and crafts, today, laser color marking provides people with A new and effective solution.

So what is the principle of stainless steel lottery? Under the action of the laser heat source, the stainless steel material generates colored oxides on the surface, or forms a colorless and transparent oxide film. It displays various colors due to the thin film interference effect of light. This is the basic principle of stainless steel color marking.

On non-metallic materials, the color of black or leaking deep substances can only be marked by oxidation. For example, the marking effect on glass is generally the depth of the marking. It is impossible to mark other colors, usually monochrome. . Some products and materials can also be colored with laser marking machines by using laser powder.
