Dot peen marking is a permanent marking method in which a hardened pin strikes a metal or hard plastic surface in a controlled pattern of dots. Driven pneumatically or electrically, the pin engraves text, logos, serial numbers, barcodes, or 2D Data Matrix codes directly into the part. Because the process adds no heat, it leaves the material's structure unaffected — the main reason it's preferred for precision and safety-critical parts.

Dot-peen marking uses a physical pin to leave deep, tactile marks you can feel by hand, while laser marking alters the surface thermally to produce shallower but higher-resolution marks. Dot-peen excels in heavy industry, casting, and outdoor environments where durability matters most, while laser marking suits fine detail and high-speed, high-volume production lines. The right choice depends on material, environment, and production speed.

Dot-peen marking machines work across a wide range of materials, including steel, aluminum, stainless steel, brass, copper, cast parts, and many hard plastics. Flat, cylindrical, angled, or recessed surfaces can all be marked with the right fixture and rotary-axis setup. Material hardness and surface geometry determine the pin type and marking parameters used.

Yes. Unlike ink or label-based methods, dot-peen marking is physically engraved into the part's surface, giving it high resistance to abrasion, oil, chemical cleaning, heat, and outdoor exposure. This is the main reason it's favored in the automotive, aerospace, defense, and energy sectors, where a serial number or traceability code needs to stay legible for the part's entire service life.
