If you are specifying a part marking and traceability system, you are usually solving one of three problems: a customer or regulator demands serialized direct part marks, an ink stamp or paper traveler is failing in your downstream environment, or a recall scope is too wide because parts cannot be traced to a specific lot or station. We engineer the station around the actual problem.
AMD Machines designs custom marking and traceability systems — fiber, CO₂, and UV laser marking plus dot peen and vision-verified barcode capture — backed by 30+ years of automation experience and more than 2,500 machines delivered. The system you buy from AMD does not just print a code. It applies a durable mark, verifies the grade, and writes a serialized record for every part to your MES.
What is a part marking and traceability system?
A part marking and traceability system is a production machine that applies a permanent, machine-readable identifier — typically a Data Matrix code, serial number, or 1D barcode — directly to each part, verifies the mark, and links it to a serialized record in your MES or quality database. The mark survives downstream processing; the data follows the part for life.
Most stations bundle four subsystems:
- A marking head — fiber, CO₂, UV laser, or dot peen — sized to material, depth, and cycle time
- A vision verifier that grades the code per ISO/IEC 15415 or 15416
- Fixturing and part handling that locates the part repeatably under the marking head
- A controls and data layer that pulls payload data from MES/ERP and logs serialized results back
How a part marking and traceability system works
- Part identification — barcode scan, RFID read, or recipe lookup confirms the part number; no recipe match, no mark.
- Load and locate — the part lands in a nest with hardened locators; vision or sensors confirm position.
- Payload generation — the controller pulls or generates the serial, lot, date, and any GS1 application identifiers.
- Mark — the laser or dot peen head applies the code at the validated power, speed, and depth recipe.
- Verify — an inline reader grades the code, confirms text legibility with OCR/OCV, and checks position against a registration feature.
- Sort and log — pass parts continue downstream, failed marks are re-marked or quarantined, and every result is timestamped to the part record.
Marking methods compared
| Method | Best for | Typical mark | Notes |
|---|---|---|---|
| Fiber laser (1064 nm) | Metals, many engineering plastics | Anneal, engrave, color change; 20–500 μm depth | Workhorse; near-zero consumables; KEYENCE MD-X, TRUMPF TruMark, IPG, Datalogic AREX |
| CO₂ laser (10.6 μm) | Paper, wood, glass, coatings, organics | Surface ablation, color change | Best for packaging and painted surfaces; Coherent and Synrad sources |
| UV laser (355 nm) | Heat-sensitive plastics, PCBs, thin-wall metals | "Cold" mark with small heat-affected zone | Slower than fiber but minimal thermal damage |
| Dot peen | Castings, forgings, weldments, heavy steel | Mechanical indent 100–500 μm deep | Survives blast, powder coat, decades of service; Telesis, SIC Marking, Ostling |
| Inkjet (CIJ/TIJ) | High-speed cartons, dated packaging | Surface print | Fastest, lowest permanence; Videojet, Markem-Imaje, Domino |
We size the method to the substrate, the required permanence through downstream processes, the mark grade you need after coating or finishing, and the cycle time — not the other way around.
Key components and technologies
- Marking sources — KEYENCE MD-X / MD-F, TRUMPF TruMark, IPG fiber, Coherent / Synrad CO₂, Telesis or SIC Marking dot peen
- Vision verification — Cognex DataMan 370/470/8072V, KEYENCE SR-2000, Omron MicroHAWK, with grading per ISO/IEC 15415 (2D) and 15416 (1D)

- Controls and HMI — Allen-Bradley CompactLogix/ControlLogix or Siemens S7-1500 with FactoryTalk View or WinCC
- Safety — interlocked guarding, beam containment, and dual-channel circuits per ISO 13849
- Data layer — OPC UA, MQTT, REST, or ODBC/SQL push to Rockwell FactoryTalk, AVEVA, Ignition, SAP, or a custom historian
Integration, controls, and traceability
A marker that prints a serial is not a traceability system. It becomes traceability when every code is verified, archived, and linked to the part's process history:
- Per-part serialized records — payload, mark recipe, verification grade, verifier image, timestamp, station ID
- Recipe management — laser power, depth, font, vision tolerance, and grade threshold switch on part-number scan
- MES integration — OPC UA, MQTT, SQL, or REST to your MES, historian, or quality database
- Local buffering — the station keeps marking through network outages; data syncs on restore
- Audit-grade reporting — exportable verification records and verifier images for quality reviews and traceability audits
Industries we serve
- Automotive — AIAG B-17 Data Matrix on castings, valve bodies, EV battery components, brake and fuel parts
- Aerospace and defense — MIL-STD-130 IUID marking on structural and rotating components

- Appliances and consumer products — model, rating, and compliance plates with serialized data capture
Why AMD Machines
We engineer the laser or dot peen station, fixturing, vision, safety, and data integration as one system — not a marking head bolted to a frame:
- 30+ years of custom automation and 2,500+ machines delivered
- In-house mechanical, electrical, controls, vision, and robotics — one supplier, one runoff
- Vision verification and Gauge R&R proven against your real parts before shipment
- Pairs cleanly with our automated labeling stations, machine vision inspection, and end-of-line test systems
Have a part, a code spec, and a takt time? That is enough to start. Request a quote and we will scope the station around it.
