Automotive Part Marking & Traceability (DPM)

Part marking traceability in automotive manufacturing breaks down when the mark stops being readable - after heat treatment, after machining, after paint. We build the system that survives all three: laser or dot-peen marking placed where it lasts, in-line vision read-back with grading, and genealogy carried across every operation.

Laser, Dot-Peen or Inkjet

Method chosen per part against substrate hardness, cycle time, cosmetic limits and the processes the mark must survive.

Vision Read-Back and Reject

Every mark is read and graded in-line, and unreadable parts are rejected before the next operation.

Genealogy to OEM Standards

Part-level history assembled across operations and released in the format your OEM customer demands.

IATF 16949 & OEM Reporting

Traceability evidence, retention rules, customer-specific requirements and recall support.

Our Automotive Part Marking & Traceability (DPM)

Mark application, verification and grading, genealogy across operations and IATF 16949 evidence - delivered as one system, with the hardware installed and integrated on your existing lines.

1. Mark Method Selection & Application
Substrate, hardness, cycle time and cosmetic rules decide the marking method. We prove the choice by marking your own components through your own downstream processes before any marker is quoted.

Key Capabilities:

Fibre laser, dot-peen and thermal inkjet marking on one line
Mark placement trials against heat treatment, blasting and paint
GS1 DataMatrix, alphanumeric and OEM-specified code formats
Marker integration with robots, fixtures, gantries and existing PLCs
2. In-Line Verification & Code Grading
A mark is only traceable if it still reads at the next plant. We grade every code in-line to ISO/IEC 29158, the AIM DPM standard, and reject anything below the agreed grade.

Key Capabilities:

ISO/IEC 29158 AIM DPM grading with a grade stored per part
Dome, bar and coaxial lighting selected per surface finish
Automatic reject and re-mark handling with clear operator prompts
Grade drift trending to flag marker and lens degradation early
3. Part Genealogy Across Operations
Machining, heat treatment, sub-assembly and test each add facts to the same serial. The genealogy record lets a suspect part trace back to its material lot, machine, tool and operator.

Key Capabilities:

Operation-by-operation event capture from PLC, MES and test rigs
Component-to-assembly parent-child linking during sub-assembly build
Raw material lot, batch and supplier certificate linkage per serial
Containment queries returning every affected serial in one search
4. IATF 16949 & OEM Reporting
Traceability audits are failed on evidence retrieval, not on data capture. We build the reporting your quality head needs for IATF 16949 and for each OEM customer-specific requirement.

Key Capabilities:

Retention rules aligned to IATF 16949 and OEM record periods
Customer-specific requirement templates configured per OEM programme
Layered process audit and control plan evidence on demand
8D and recall support with affected-serial lists in minutes

Key Performance Indicators

The numbers a quality head and a manufacturing engineering head sign off on. Targets are design goals agreed in writing before any hardware is procured.

First-Read Rate at Station
Share of marks read correctly by the vision system on the first attempt at full cycle time.
Target: >99.5%
How we get there: Achieved through mark trials, lighting design and reader positioning on your own parts.
DPM Grade Retention
Code grade still achieved after the downstream heat, machining and finishing steps.
Target: Grade B or better
How we get there: Engineered by testing depth, contrast and placement before the marking method is fixed.
Trace-Back Query Time
Time taken to return every serial affected by a suspect material lot, machine or shift.
Target: Under five minutes
How we get there: Delivered by indexed genealogy records rather than reconstruction from paper travellers.
Cycle Time Impact
Additional station time added by marking and verification on an existing line.
Target: Under two seconds per part
How we get there: Minimised by marking during an existing handling movement wherever the fixture allows.

How We Deliver

A staged sequence that proves the mark survives your process before the plant is committed.

Step 1: Requirement Study & Process Route Mapping
We walk each operation, record substrate, hardness and finishing steps, and confirm which OEM customer-specific requirements apply to the parts in scope.
Step 2: Solution Design & Marking Trials
Sample parts are marked and graded through simulated downstream processes, then marker, reader and lighting selections are signed off before procurement.
Step 3: Pilot on One Line
The system runs on one line against agreed acceptance criteria, so read rate and grade retention are proven on your own components.
Step 4: Rollout, Validation & Support
Remaining lines and stations are commissioned, audit evidence packs are prepared, and the system moves into an AMC with defined response times.

Why Choose Our Automotive Part Marking & Traceability (DPM)?

Why component makers choose an engineered marking system over a marker bought separately from the software meant to read it.

Read Rate Is Our Responsibility
We own the marker, the reader, the lighting and the software together, so nobody can blame the other supplier when grades start dropping.
Trials Before Procurement
The marking method is chosen from tests on your own parts through your own processes, not from a datasheet describing a similar substrate.
Built to OEM Requirements
Each OEM specifies code format, placement, grade and data submission differently. Yours are engineered in rather than handled as a spreadsheet workaround.
Works With Legacy Equipment
Older machines with limited interfaces are integrated through PLC tapping, sensors or a scanning station, so traceability does not wait for a capex cycle.

Frequently Asked Questions (FAQs)

1. What is direct part marking (DPM) traceability in automotive manufacturing?

Direct part marking is the practice of applying a permanent identifier, usually a 2D DataMatrix code, onto the component itself with a laser or dot-peen marker rather than onto a label that can fall off. Part marking traceability in automotive plants combines that mark with in-line vision read-back, so every shaft, housing or casting carries a serial linking it to its material lot, machine, tool and test results.

2. Is this a product we licence, or a custom-built system?

It is custom-built. We are a solution development and systems integration company, not a SaaS vendor. Every project begins with a requirement study of your process route, substrates and OEM obligations, and the system is engineered to that specification.

3. Do you supply the markers, cameras and readers as well?

Yes. Laser and dot-peen markers, DPM readers, lighting, fixtures and reject mechanisms are scoped, supplied, installed and integrated. We stay accountable for read-rate performance on your line, not only for the software layer above it.

4. How do you decide between laser, dot-peen and inkjet marking?

The decision comes from substrate hardness, cycle time, cosmetic and fatigue constraints, and the processes the mark must survive. Laser suits hardened steel and cosmetic surfaces, dot-peen suits forgings facing shot blasting, and inkjet suits lower-value parts marked late in the route.

5. Will the mark survive heat treatment, machining and painting?

That is what the trial stage establishes. We mark sample parts, run them through your actual heat treatment, blasting, machining and paint steps, then grade the codes. Where a mark cannot survive, we move the placement or add a re-mark station.

6. How is code quality measured, and what grade should we target?

Codes are graded to ISO/IEC 29158, the AIM DPM standard, which scores cell contrast, modulation and fixed pattern damage on curved, low-contrast surfaces. Most OEM customer-specific requirements ask for grade B or better at despatch.

7. Can it integrate with our existing MES, ERP and machine PLCs?

Yes. We integrate with SAP, Oracle, Navision and Tally, with MES and quality systems for operation data, and with machine PLCs over Modbus, OPC UA or direct I/O. Where no interface exists, we add a scanning station.

8. Can the system be deployed on-premise instead of on cloud?

Yes. On-premise, private cloud and hybrid deployments are supported. Many component makers keep genealogy data inside the plant because OEM contracts restrict where production data may reside, and the system keeps running without internet.

9. How long does a typical implementation take?

A single-line pilot is usually commissioned within eight to fourteen weeks of requirement sign-off, depending on marker lead times, trial results and the number of operations feeding the genealogy record. Rollout follows in phases.

10. What happens after go-live?

The system moves into an agreed support arrangement covering defined response times by severity, preventive maintenance of markers and vision hardware, grade trend reviews, and changes when an OEM revises its traceability requirement.
