Dot Peen Marking Machine
A dot peen marking machine (pin stamp) is an automated device that uses a pneumatically or electrically driven stylus to indent a series of small dots into a surface, forming characters, logos, or codes
It is a form of mechanical engraving. The dot matrix pattern creates permanent markings on metal or hard plastic parts.
Type of Dot Peen Marking Machine
Benchtop/Stationary Markers: Table-mounted machines for marking smaller parts in one fixed location.
In-line/Integrated Systems: Markers integrated into production lines for automotive stamping, aerospace parts, etc., often with robotic feeders.
Portable/Handheld Units: Less common; some small dot-peen heads can be hand-held on large
structures (bridges, heavy equipment).
Applications in Various Industries
Used for industrial traceability and identification. Common in aerospace, automotive, and electronics to mark serial numbers, barcodes or Data Matrix codes on metal parts. Because the marking is deep and durable, it survives extreme conditions (heat, abrasion). In India, dot-peen is used for marking machine tools, dies, oil field equipment, and any part needing legible, permanent ID.
Material Selection Considerations
The marking pin is usually tungsten carbide for hardness. The machine frame is heavy steel to absorb impact. Surfaces to be marked must be rigidly clamped (fixtures of steel or cast iron). Air lines (for pneumatic systems) use oil-free compressors. The electronics must handle industrial environments (dustproof casing). Since marking is low-stress on parts, there’s little concern for material compatibility (works on any hard substrate).
FAQ's
What all advantages are there for using Dot Peen Marking? The advantages are there for using Dot Peen Marking are, it has relatively low-stress indenting, it has an ability to mark through any coatings or film surfaces, it is adjustable for marking depth for light or deep marks, etc.
Why Choose Dot Peen Marking? Manufacturers may improve output throughput and reallocate valuable labor resources by upgrading to dot peen labeling. They often benefit from highly legible and precise product markings, which eliminate the need for rework, scrap, or testing as a result of incorrect product recognition.
What all things or products can a Dot Peen Marking Machine Mark? Dot Peen Marking Machine has a wide range of capacity in marking many products and materials like Aluminium, Plastics, Hard Materials whose hardness level is up to 62HRC, Structural Steel, etc and it is widely adopted for many industrial applications like Round Pipe, Painted, Plated or Galvanized products, Tags, 1D & 2 D bar codes, Logos, Serial Numbers, Batch numbers, Dates, etc.
