Flat worktable, or rotary axis for round parts.
Standalone touchscreen, or your PC over USB.
The HeatSign pneumatic dot peen marking machine makes deep, permanent marks on metal and hard plastics. An air-driven carbide pin strikes the part, so the mark is pressed into the surface. It will not rub off, even under paint or rust. Use it for text, numbers, logos, VIN codes, serial numbers, dates, lot codes, Data Matrix codes, and circular text. It is built for small and medium industrial metal parts, not for very large items. Choose a touchscreen or PC, flat or rotary, and your marking area size.
Deep marks up to 1 mm. Depth depends on the material hardness. They survive paint, rust, and wear.
Marks metal up to 60 HRC. No fumes, no ink.
Optional rotary axis for round parts, best run from PC software. Choose your setup before you buy.
A rugged pneumatic marking machine — also called a pneumatic pin marking machine — built to press deep, permanent marks into metal parts. Here is what that means for your shop.
Dot peen is made for small and medium industrial metal and hard plastic parts. It presses a pattern of dots into the surface. Here are the materials it marks best.
Stainless steel, carbon steel, aluminum, brass, copper, titanium, and cast iron — metal with a hardness up to 60 HRC.
Tough engineering plastics that can take a struck mark without cracking.
Good to know: Good to know: This dot peen machine is made for small and medium industrial metal parts. It is not meant for very large or very hard parts, or for very fine micro-detail. It is at its best on tags, plates, housings, and round parts where a deep, durable mark matters.
Send us your material type, sample photo, and marking requirement. HeatSign engineers will help test the Pneumatic Dot Peen Marking Solution for deep, permanent mark results.
Watch the marks form on the left. Read the simple steps on the right.
The clip shows deep, clear dots forming on a steel part. The part is clamped on the table. Only the pin moves.
There is no ink and no smoke. The mark is pressed into the metal, so it will not wipe off.
The same setup marks tags, plates, housings, and round parts with the rotary axis.
A pneumatic dot peen marking machine uses compressed air to drive a hard pin that punches tiny dots into the part. Here are the steps:
1. Compressed air drives a hard carbide or tungsten pin.
2. The pin impacts the workpiece surface at a high frequency.
3. An X-Y system moves the pin to “draw” each letter or code as a pattern of dots.
4. Air pressure and dwell time set the impact force, which sets the marking depth. There is no ink, no heat, and no fumes.
Tell us your part and job, and the setup follows. Three choices: controller, work table, and marking area.
Need the part held in place? We can add a fixture holder to keep marks clean and repeatable.
Pick the size by your part. The standard area is 120 x 80 mm. Larger areas suit bigger plates and panels.
Standard. Tags, small plates, and most part numbers.
Medium. Bigger nameplates and panels.
Large and extra large. Big plates and long layouts.
Not sure how to match the options? Here are common setups our customers use.
Clear, deep VIN, engine, and chassis marks that meet standards.
Touchscreen + Flat + 200 x 150
Auto-numbered tags, marked fast.
Touchscreen + Flat + 120 x 80
Marks that wrap round parts evenly.
PC + Rotary + 150 x 120
Part, lot, and batch codes for traceability on fab parts.
PC + Flat + 300 x 200
Serials that stay readable after coating, paint, or shot-blasting.
PC + Flat + 120 x 80
Serial and batch marks on valves, flanges, and pipe fittings.
Touchscreen + Flat + 120 x 80
Both make permanent marks, but they work in different ways. The simple rule: dot peen is for deep, durable marks on small and medium metal parts. Laser is for very fine detail and very small or very hard parts.
Point | Dot Peen (this machine) | Laser Marking |
|---|---|---|
Mark type | Deep struck indent | Surface mark |
Survives paint / coating | Yes | Limited |
Best for | Small & medium metal parts | Very small / very hard / fine detail |
Fine / tiny detail | No | Yes |
Fumes | None | Some |
Up-front cost | Lower | Higher |
Needs air supply | Yes | No |
Our quick recommendation: Choose this dot peen marking machine for deep, low-cost, coating-proof marks on small and medium metal parts — VIN codes, nameplates, and traceability on steel. It is not the right tool for very large or very hard parts, or for very fine micro-detail.

Yes. This is a pneumatic machine, so it needs shop compressed air to drive the pin. It runs on 0.2 to 0.6 MPa. Most workshops already have an air line that works. If you do not have air, ask us about an electric dot peen marker instead.
Pick by how you want to run it. Choose the touchscreen if you want a standalone machine on the shop floor. Choose PC if you prefer to manage files on a computer. You select one before you buy.
Marks go up to about 1 mm deep. The exact depth depends on the material hardness – softer metals take a deeper mark, harder metals a shallower one. Because the mark is pressed into the metal, it stays readable under paint, rust, and rough handling.
Best for small and medium metal parts, such as tags, plates, nameplates, and housings. Not for very large parts or very fine micro-detail. Add the rotary axis for round parts.
It marks steel, stainless, aluminum, brass, copper, titanium, cast iron, and hard plastics. The limit is about 60 HRC. For most industrial metal parts, that covers the job. Send us your material details if you are not sure and we will confirm.
Yes, with the optional rotary axis (D100, for cylindrical parts up to 80 mm diameter). For rotary marking we recommend the PC software, which makes round-part layouts easier. The axis turns the part while the pin marks, so text and codes wrap evenly around tubes, rings, and small valves. Tell us your part diameter and we will match the setup.
Dot peen does make noise, since the pin strikes the metal. In a normal workshop this is fine. For quiet offices, you can add an enclosure. The part should be clamped or fixtured so the mark stays clean and in the right spot.
The hard-alloy tungsten pins last a long time and are easy to swap. Every machine has a 1-year warranty and lifetime online support. Production is about 5 working days, then air express takes a few more days. As the maker, we ship direct and help you set up.
Send us your part, material, and what you need to mark. Our engineers will reply with the right setup, a marking solution, and a clear quote. No cost, no obligation.
Factory-direct. 1-year warranty, lifetime online support, and worldwide shipping.
For metal parts that need deep, permanent, and durable identification, a pneumatic dot peen marking machine offers a practical solution. See how users evaluate HeatSign after daily workshop use, with feedback on marking depth, part stability, air pressure, and long-term
The marking depth is good, especially on steel plates and brackets. The only thing our operator learned quickly is to clamp the part firmly. If the part moves during marking, the characters can look slightly uneven.
We use it for part numbers on steel brackets and replacement parts. The machine is straightforward, and the marks are deep enough for normal shop handling. The air compressor setup is necessary, but maintenance has been easy so far.
