About Dot Peen Marking

Dot peen marking technology allows manufacturers to automate their part marking process, ensuring 100% reliable product traceability.

  • Eliminate mis-marked products
  • Stamp on rough or uneven surfaces
  • Use 2D Data Matrix codes for greater traceability
  • Use fixturing for easy and consistent marking
  • Integrate with host systems, retrieve data from bar code scanners, spreadsheets, or databases

Why Choose Dot Peen Marking?

By upgrading to dot peen marking, manufacturers can increase production throughput and reallocate valuable labor resources. They also enjoy downstream benefits from highly legible and accurate product marks, eliminating the need for rework, scrap, or testing due to improper product identification. Compare dot peen marking to other methods of permanent part marking:

Dot Peen Marking
Hand Stamping
Chemical Etching
  • Low-stress indenting
  • Flexible and programmable for fully automated marking
  • Adjustable marking depth for light or deep marks
  • Can mark through any coating or film on part surface
  • Time consuming to make or change marks
  • Prone to errors
  • Can cause worker injuries
  • Non-programmable; mark information cannot be automatically created or stored
  • High consumable costs
  • Requires use of hazardous chemicals
  • Multi-step process is difficult to automate
  • Marks on conductive surfaces only

How Dot Peen Systems Work

Pannier programmable stampers use a pneumatically driven stylus to stamp (or peen) a series of very small, closely spaced dots to form straight or curved lines. Also called micropercussion technology, the dot peen marking method provides fast, flexible, and consistent marks while exerting minimal force on the part surface. You can mark text, logos, or 2D Data Matrix codes in any size or orientation.
