| Message: | Shenzhen MG Technology Co.,Ltd is one of the leading China color laser marking machine manufacturers and suppliers,Website:http://www.mglasermachine.com, equipped with professional factory we are always able to produce low price color laser marking machine, laser etching machine for metal, fibre laser engraving machine with reliable quality.Laser marking technology has been from the beginning of high speed development to stable development stage, in stainless steel marking field appeared new technology: laser print color on stainless.Principle of Color laser engraving (3 ways): 1.Create a colored oxide;2.With chemical, electro-chemical or under the action of laser, create a thin, transparent colorless oxide film, with interference effect of oxide film, color will be showed on stainless surface;3.A mixed state which simultaneous has colored oxide and oxide fiilm.MOPA laser stainless steel color marking:The advantage of MOPA laser: its pulse width and frequency can be adjusted independently, one of them will not affect the other laser parameters, which is not available in the Q-switch structure laser. MOPA structure of this characteristic, make the stainless steel color marking with an infinite possibility. In the actual operation, the pulse width, frequency, power, speed, filling method, filling spacing, delay parameters, etc., will affect the color effect. The impact of these parameters, will make the diversification of color changing characteristics , is a mutual connection, mutual influence.Pulse width and frequency, is the characteristic of MOPA laser, mutual independence also can be adjusted; these two parameters is also the most important parameters in the stainless steel color engraving, they can mix, can make up a colorful world.Speaking of laser power, we must know well, it is able to influence the output of laser single pulse of the most intuitive control variables. After testing, when laser color engraving on stainless, we found that the frequency is “contest”......url:http://www.mglasermachine.com |
