Laser marking machine in the stainless steel on the color effect of the method
Domestic laser marking machine has been developed from the beginning to the rapid development of the rapid development of the stage, in the domestic application is also more extensive, then in order to seek new business growth point of expansion in the field of stainless steel marking the emergence of the expansion The new process of stainless steel color marking, laser marking machine to create another era.
Stainless steel color of the principle, there are three color mode: First, the formation of colored oxides; Second, by chemical, electrochemical or laser, the surface of stainless steel to produce a layer of very thin transparent colorless oxide film, oxide film interference Effect, you can show the color in the table; Third, there is a colored oxide and oxide film of a mixed state.
Color laser marking machine with the ink deposition technology and those through the application of color powder or film technology is different, more advanced laser marking machine to change the plastic color of this typical physical effect with the polymer in the oxygen environment thermal decomposition reaction In contrast, in the metal raw material surface can produce a variety of colors.
Laser marking of stainless steel laser color changes in the corresponding relationship between laser energy, laser, stainless steel table and the laser thermal effects. Through the laser thermal effect, it is concluded that the laser energy density is directly proportional to the film thickness. As the laser energy increases, the color of the stainless steel watch changes in the following order of colors: orange-red-violet-blue-green-blue-green-green-yellow green-yellow-cheng-red.
Can be arbitrary editing various text patterns, very easy to operate: absolute environmental protection, pollution-free; marking speed, the stainless steel products industry, the application of color laser marking can add the color of the graphics can be large-format stainless steel products Product value-added, and enhance the international competitiveness of domestic stainless steel products.
