Direct Part Marking: Selecting the Right Technology

Printing 1D bar codes has been a fact of life for well over 40 years. It became most recognizable in 1974 with the implementation of UPC system that we see on almost every product that we buy.

The ability to mark a machine readable code directly on a part or component, however, has been more recent in development. While marking human readable information on parts has been available for over 100 years, marking 1D, 2D, and other codes, with high readability rates, has been a challenge. DPM is now a requirement for most successful traceability application. Automotive, aerospace, health sciences, electronics, semi-conductor, and many others, all depend on DPM to ensure production effectiveness, lifetime traceability, security, and quality. In addition, DPM allows for robust anti-counterfeiting and diversion programs. In some industries, certain DPM methods are specified in industry standards.

The main technologies for DPM are:

  • Ink Jet
  • Chemical Etch
  • Dot Peen
  • Laser (etching and annealing)

With many years working directly on DPM applications, Global Automation and Identification Group has the experience and expertise to assist you with selecting the appropriate method for any application and one that complies with any associated industry standard.
