A Dot Pin Marking Machine is an industrial marking machine for permanent marking on different materials like metal, plastic, or hard alloys. It works by employing a stylus or pin that impacts the surface quickly, producing a sequence of small dots that can create numbers, letters, logos, or serial codes. These machines are commonly applied in manufacturing, automotive, aerospace, and metalworking industries for part identification and traceability. Famous for their long-term use and accuracy, dot pin marking machines may be automated or manual and can mark on uneven, flat, or curved surfaces with little wear on the marking tool.
