What is Dot Peen Marking?

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

  • Eliminate mis-marked products
  • Stamp on rough or uneven surfaces
  • Use 2D Data Matrix codes for greater product 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

Dot peen marking machines use a pneumatically driven marking pin to stamp (or peen) a series of very small, closely spaced dots to form straight or curved lines. Also called pin marking technology, the dot peen marking method provides fast, accurate marks while exerting minimal force on the part surface. Text, logos, and 2D Data Matrix codes can be marked in any size or orientation.
