Laser marking is a non-contact printing method that offers advantages over other technologies including mark quality, permanence and fewer consumables. Laser sources in different power outputs to address a range of substrates and applications. It offers excellent opportunities for making high-precision printing, embossing, erosion, or injection tools. The great advantage over the conventional spark erosion technique consists in the fact that laser engraving is extremely flexible material. The material type and laser power level determine the maximum engraving depth and speed of engraving. Typically shallow engraving is a faster process than deep engraving. Additionally, lower density materials engrave faster than higher density materials. Increasing laser power level generally improves laser engraving speed.
