Direct part marking

Part marking provides machine-readable identification for the automotive and aerospace industries

The practice of Direct Part Marking (DPM) is used across many industries to identify an array of end use items. This process, also referred to as machine-readable identification, is prevalent in the automotive and aerospace industries for marking alphanumeric and 2D DataMatrix codes on individual parts and assemblies.

Direct Part Marking, the new standard in parts coding DPM standards have been adopted by a number of associations within the automotive and aerospace industries. Marking parts with machine-readable codes allows for a part to be tracked throughout the manufacturing process and the supply chain.

Manufacturers can use DPM to track parts throughout the manufacturing process and supply chain. It is ideal for locating parts for service or recall and can assist in liability and warranty resolution.

Marking methods

Aside from selecting code formatting and content, it is also important to consider the best method for marking the part. The benefits of DPM are typically greater than that of other options, such as label application. However, the physical characteristics and make-up of the part can also result in marking issues for manufacturers. For the automotive and aerospace industries, the most common coding methods are laser marking, continuous ink jet printing, dot peening and electrochemical etching. When comparing these marking technologies, it is important to focus on the material to be marked, the flexibility of the process, cost factors, speed, throughput and opportunity for automation of the marking process. DPM can be used on a wide variety of materials, but each substrate has unique aspects such as roughness of the substrate, ability to withstand thermal stress, and fragility of the material being marked.
