Industrial Traceability: Data Matrix Marking and Part Identification

Many standards require permanent part identification. ISO 9001 requires product identification and traceability where applicable; IATF 16949 in automotive and AS9100 in aerospace reinforce this requirement.

In medical devices, EU MDR 2017/745 and ISO 13485 require the UDI on the device itself when it is reusable, most often as a GS1 Data Matrix. For US defence equipment, MIL-STD-130 requires UID marking as an ECC200 Data Matrix. In cosmetics, EU Regulation 1223/2009 requires a batch number on every unit.

Code quality is itself standardised: ISO/IEC TR 29158 grades the legibility of a direct part mark from A to F, and many OEMs require a minimum grade.

When a defect is detected, part traceability isolates precisely the serial numbers or batches concerned. The recall is limited to products actually affected, rather than an entire range.

This precision protects users, contains costs and safeguards the manufacturer’s reputation.

An identifier read at every workstation feeds the quality system with real data: which machine, which operator, which material batch, which settings. Non-conformity analysis becomes factual and fast.

That data drives continuous improvement and reduces scrap, making industrial traceability a performance tool rather than a mere constraint.

A permanent mark that is hard to reproduce, such as a laser-engraved Data Matrix or a MetalPhoto nameplate, authenticates a genuine part. It protects the brand, its customers and end-user safety, especially for critical spare parts.

A serial number identifies a single part; a batch number groups parts produced under the same conditions. The former is essential for critical components and medical devices, the latter is often sufficient for consumables and cosmetics.

Marking software handles automatic incrementing and prevents duplicates, securing day-to-day part marking.

The Data Matrix is the most widely used 2D code in industrial traceability. Standardised as ECC200, it embeds error correction that allows reading even when part of the code is damaged.

Highly compact, it can be engraved on a few square millimetres, on a screw, an implant or a circuit board. It carries the serial number, date, reference and much more, following GS1 or UID standards.

The QR code can be read with a smartphone, which makes it practical for maintenance, user instructions or end-user authentication. The linear barcode remains common in logistics, but it needs more surface and tolerates wear less well.

For permanent marking on a part, Data Matrix or QR codes are preferable to 1D barcodes.

Human-readable text remains essential: reference, date, operator, logo, CE marking or regulatory symbols. It complements the 2D code and allows identification without a scanner.

Laser and pad printing reproduce logos and fonts with fine detail, even on very small parts.

AS9100, IATF 16949 and defence UID requirements demand a permanent mark that stays legible for the part’s whole life, including after painting or heat treatment. Deep fiber-laser engraving and MetalPhoto nameplates are the norm. See our solutions for automotive, military and aeronautics.

Surgical instruments, implants and laboratory consumables carry a UDI compliant with EU MDR 2017/745. Laser annealing on stainless steel and UV marking on polymers ensure legibility after repeated sterilisation. Discover our answers for healthcare, medical and laboratory.

Tools, moulds, machined parts and raw castings are identified for asset management, warranty and anti-counterfeiting. Deep engraving and engraved plates withstand shot blasting and harsh workshop environments. See our solutions for industry, tools and metalworking.

EU Regulation 1223/2009 requires a batch number on every bottle, tube or carton. UV laser, pad printing and UV printing mark packaging without spoiling its appearance. Explore our applications for wellness and cosmetics.

Bare metal, plastic, glass, painted surface: the material points to a fiber, CO₂ or UV laser, or to an attached plate when the part is inaccessible. The environment matters just as much: heat, oil, chemicals or outdoor exposure call for a recessed permanent mark or a sealed plate.

A code read for twenty years by an industrial scanner has different requirements from a batch read once in logistics. Plan the contrast, the Data Matrix cell size and the abrasion resistance according to the part’s real life cycle.

A standalone laser station is sufficient for batches and quality control. A galvo station integrated into the line, driven by your production management system, marks and verifies every part without slowing throughput.

Each sector combines a standard, an identifier type and a preferred marking technology. The table below summarises the most common cases: use it as a starting point, as your customers’ specifications and your audits remain the final reference.
