Dot Peen Marking (Dot Peening) / Needle Embossing or micro percussion (micro dot marking) is a marking technique for Permanent Direct Part Marking within the field of material deformation (deforming), that corresponds to graining

Dot Peen Marking Systems for tamper-proof, durable, flexible markings

With needle embossing (also called point of percussion technology), materials are marked using a carbide tipped tool (needle) that oscillates through compressed air application and moves in an X and Y direction during its upward and downward movements.

This results in a dense sequence of individual dots (writing) being punched into the material. Depending upon the needle frequency, a complete line can result.

Characters, digits, logos and 2D codes (Data-Matrix™) can be imprinted in the field as desired.
