Due to the advanced nature of laser, the stainless steel color laser marking machine will soon replace the traditional color ink/film printing technology.Because the color laser marking machine, unlike the ink deposition technology and those that use color powder or film technology,advanced lasers can change the physical effects of the material's color, and react with the polymer in an oxygen environment by thermal decomposition.Therefore, marking the surface of metal raw materials can produce various colors.
The correspondence between color change and laser energy in stainless steel laser color marking:
Under the action of laser,the surface of stainless steel will with laser thermal effect.Through the laser thermal effect, laser energy density is proportional to film thickness.As the laser energy increases, the color of stainless steel surface changes according to the following color order: orange - red - purple - blue - green - blue - green - green - yellow - green - yellow - yellow - clear - red.
Can edit all kinds of text patterns, easy to operate: absolute environmental protection, no pollution,fast marking speed. For the stainless steel products industry, color laser marking can add color of marking graphics, greatly improve the added value of stainless steel products, and enhance the international competitiveness of domestic stainless steel products.
