What is Dot Peen Marking?

Dot Peen Marking Process Definition

Dot peen marking is a very effective and lasting marking technique that employs a pin or stylus to make indentations or dots on the surface of a material. Dots are formed by pneumatic or electric means, which cause the stylus to penetrate the material at a predetermined force to produce accurate letters, symbols, or DataMatrix codes.

How It Works

The technique is characterized by the direct and controlled movement of a stylus that results in creating indents on the surface of the material. These indents possess the characteristic of long-lasting visibility making them suitable for industrial applications where permanent marking is required.

Applications: The process is applicable to metals, plastics, and even variously hard materials, with accuracy and depth consistency being the main advantages.

Modern dot peen marking systems typically feature computerized controls and automated features for enhanced precision and efficiency.
