Name:UV laser marking machine standard

When the laser marking machine marks the general metal material, the lines and the light reflectance of the lines are different from the original lines due to ablation of lines (depths of several micrometers to several tens of micrometers) of a depth of several microns or more. Eyesight contrast effects, so that people can feel these lines (as well as the lines formed by the code, numbers, patterns, trademarks, etc.). For glass, these ablated lines have a “staggered light” effect; for plastics, due to photochemical reactions and ablation, there are visual contrasts and sulking effects. If the surface of the material is coated with a special colored material for marking, the colored material will be fixed (a high-temperature ablation of the material) and it will be colored on the line.
