Laser marking on metal components produces contrast and color in two ways. Color laser marking produces different shades of green, red and yellow. The target area is left lighter than the rest of the component. Carbonizing destroys the carbon bonds in the component, causing the marked area to be darker than the rest of the part. Generally, this process is used on light plastics and organic materials. The process can be expensive, and requires specialised equipment and a highly skilled workforce.<\/p>\n\n\n\n

One method for laser marking on metal components is annealing. During the annealing process, a focused laser beam is applied to the surface of the target material. The laser heat causes a chemical reaction, releasing oxygen and hydrogen from the surface of the material. The result is a distinctive marking. This technique is ideal for steel and most plastics containing carbon molecules. It also allows users to control the intensity and duration of the laser beam, making it more versatile and cost-effective than other marking methods.<\/p>\n\n\n\n
