Traceability is becoming an essential part of modern manufacturing.

Each product may need a unique code that links it to production information.

Laser marking can create that identifier directly on the material.

QR Codes

A laser can mark two-dimensional codes containing data or links to external systems.

Applications include:

• Product traceability

• Authentication

• Production history

• Service records

• Digital product information

Barcodes

One-dimensional barcodes remain widely used in:

• Warehousing

• Production control

• Logistics

• Inventory management

Serial Numbers

Unique serial numbers make it possible to identify individual products or batches.

Laser marking systems can generate changing numbers automatically during production.

Permanent Identification

Unlike adhesive labels, laser marks are created directly on the suitable product surface.

This can help maintain the relationship between the product and its identification information.

Automation

Laser traceability systems can be combined with:

• Vision positioning

• Production-line marking

• Variable databases

• MES connectivity

• Automatic code generation

Conclusion

Laser marking can become an important component of a complete traceability system by creating permanent serial numbers, barcodes and QR codes directly on industrial products.
