What Is A Dot Pin Marking Machine

Permanent traceability, struck straight into the metal.

A dot pin marking machine — also called a dot peen or micro-percussion marker — uses a hardened carbide pin driven by compressed air to strike the component at high frequency. Each strike leaves a micro-indentation; thousands of them, placed by precise X and Y axis movement, form readable characters, logos and 2D Data Matrix codes.

Because the pin displaces metal rather than cutting it away, no material is removed and no stress-raising notch is created. The mark survives shot blasting, painting, galvanising, oil, heat and years of handling — which is exactly why automotive, forging and aerospace suppliers rely on it for part traceability.

ANC has been manufacturing these machines in Chakan, Pune since 2009, with PC-based, touchscreen and fully portable variants, plus in-house spares and 24 × 7 service across India.

How It Works

From design file to permanent mark in four steps.

01

Design is loaded

Text, serial numbers, logos or 2D Data Matrix codes are entered on the controller, or imported over USB as .PLT, .DXF or .SLG files.

02

Head positions on X–Y

Stepper-driven axes position the marking head to 0.02 mm accuracy, following straight or ARC marking paths.

03

Carbide pin strikes

Air at 4–6 Bar drives the hardened indentor pin, striking the surface at high frequency to form micro-indentations.

04

Mark is formed

Metal is displaced, not removed — the mark survives paint, galvanising and heavy handling without weakening the part.

Main components of the machine

Knowing the anatomy of the machine makes daily maintenance and troubleshooting straightforward — and every one of these parts is stocked by ANC.

Dot pin vs. laser marking

Feature Dot Pin Marking Laser Marking
Marking technology Impact technology - generates noise while marking Non-Impact technology - silent marking
Marking depth Deep structural indentation (0.1 – 0.8 mm) Shallow surface alteration (~0.2 mm)
Consumables Very low — occasional indentor pin change No physical consumables
Best suited for Heavy metals, thick automotive & forged parts Fine detail, logos, high-speed batch marking
Survives painting / galvanising Yes — depth keeps the mark readable Can be covered by thick coatings

How to operate it

  1. Clamp the component firmly on the fixture to stop vibration.
  2. Enter the text, serial number or barcode in the controller software.
  3. Set the pin-to-surface height using the hand wheel.
  4. Run a dry test cycle to confirm position and layout.
  5. Start the marking cycle and let the pin complete the path.

ANC installs the machine at your plant and trains your operators on these steps — anywhere in India.

FAQ

Questions we get before every purchase.

Still unsure which variant fits your component? Send us the part drawing — we'll recommend the working area, fixture and pin size.

What is a dot pin marking machine?

A dot pin marking machine is a pneumatic impact marking system. A hardened carbide pin strikes the metal surface at high frequency while X and Y axes move the head, forming a permanent mark out of closely spaced micro-indentations — text, serial numbers, logos or 2D Data Matrix codes.

How deep does it mark, and on how hard a material?

ANC dot pin machines mark 0.1 to 0.8 mm deep and support material hardness up to 65 HRC, so mild steel, alloy steel, hardened components, cast iron, aluminium and brass are all covered.

Does dot pin marking weaken the component?

No. The pin displaces metal instead of cutting it away, so no material is removed and no stress-raising notch is created in the base material.

Dot pin or laser — which should I buy?

Choose dot pin for deep, permanent marks on thick or heavy metal parts that go through painting, galvanising or rough handling, and for a much lower capital cost. Choose laser for very fine detail, logos and very high-speed batch marking on finished surfaces.

What does the machine need to run?

A 230V, 50Hz, 5A single-phase supply and a compressed air line at 4 to 6 Bar. Designs can be loaded over USB in .PLT, .DXF or .SLG format.

Do you customise working area and fixtures?

Yes. Working area, fixture design, rotary attachments and automation/integration with your production line are customised. ANC also delivers, installs and trains operators anywhere in India.
