Dot Peen Direct Part Marking

Dot Marking, Impression Marking, Pin Marking

Dapra offers a variety of low-stress, economical, permanent dot peen marking solutions for direct part marking and identification. Programmable 2-, 3- and 4-axis systems can be provided. We offer dot peen marking solutions for use in CNC machines.

Dot peen marking involves permanently indenting dots (spherical recesses) into a component with a stylus (needle, pin, etc.) with a specific end geometry (typically 90 or 120 degree included angles) and a point radius (typically 0.005” to 0.010”). The initial concept of dot peen was to create alpha-numeric characters, symbols and 2D codes consisting of individual recesses that did not overlap, unlike micropercussion and vibro peen.

Dot peen is considered a low-stress method of marking, making it ideal for most aerospace and oil & gas applications. Most materials (up to 65 HRC) can be marked with the dot peen process. It provides a clear, cost-effective solution for permanent identification and marking data matrix codes.

Advantages:

  • Permanent marks
  • Good marking depth
  • Highly visible mark in most applications
  • Inexpensive technology
  • Low-stress marking

Disadvantages:

  • Low contrast of mark in some applications
  • Low resolution of logos/graphics

The dot peen process can be used in almost any industry, but it is best suited for aerospace, oil & gas and general manufacturing.
