Range of Materials
Dot peen engraving can mark a wide range of materials, including metals (such as steel, aluminum, and brass), some hard plastics without compromising the surface integrity. Etching, however, is limited to materials that can withstand chemical processes, such as certain metals and glass. This limitation restricts its use across different industries. The versatility of the dot peen marking machine makes it suitable for a variety of industrial applications, including marking on the surfaces of flanges, valves, etc.
