What is direct part mark?

Direct Part Marking (DPM) is a process of permanently marking a product or component with a unique code to enable its identification and traceability throughout the manufacturing process, distribution, and life cycle. The codes can be symbols, alphanumeric characters, or patterns such as a 2D barcode.

DPM enables automatic identification and tracking of components and products from raw materials to the finished goods, ensuring quality control, reduce errors, and increase efficiency in the production process. The mark can be made using a variety of methods, including laser etching, dot peen marking, and chemical etching.

DPM is widely used in industries such as automotive, aerospace, and defense, where traceability and quality control are important. It also helps to improve supply chain management and reduce counterfeiting and fraud. With the advancement of technology, DPM has become more efficient and cost-effective, making it more accessible to various industries.
