Direct Part Marking, the new standard in parts coding

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.

1. What is Direct Part Marking?

Direct Part Marking (DPM) is the process of marking parts with unique machine readable codes containing key product information. Part marking allows products to be traced through the supply chain and each part’s lifecycle. Part identification also decreases the need for manual code entry, improves code accuracy and reliability, and quickens data exchange.

2. What is traceability and why is it important?

Traceability is a process used to track a part throughout its lifecycle using a unique identification code. Traceability allows buyers to:

  • Control the supply chain by keeping track of parts across the production process.
  • Quickly locate parts for recall campaigns and service inquiries.
  • Meet growing requirements and regulations.
  • Protect against counterfeits.

3. Are there any changes in the industry?

The industry is moving from one-dimensional (1D) to two-dimensional (2D) coding (also known as Data Matrix codes).
2D codes:

  • Contain more information in a small amount of space.
  • Can be applied with a variety of direct marking methods.
  • Have greater reading reliability.

4. Which factors should a buyer consider when evaluating marking technologies?

  • Substrate/Application (the surface being marked).
  • Production Line (ease of integration and mobility).
  • Budget (balancing upfront costs with lifetime upkeep).
