Body in White: How Laser Marking Eliminates Traceability Failures on Production Lines

In Body in White (BIW) production, reliable part traceability is a non-negotiable requirement. Yet many OEMs and automotive suppliers still rely on adhesive labels applied to e-coated steel components. The result: frequent label detachment, traceability gaps, and significant hidden costs. SIC Marking offers a permanent alternative with its FIT laser marking system, designed to integrate directly into BIW production lines.

Why Adhesive Labels Undermine Body in White Traceability

E-coated surfaces have properties that significantly reduce label adhesion. Thermal and mechanical stresses along the production line make the situation worse. The operational consequences are immediate:

Loss of part identification before or after surface treatment
Non-conformities detected at end-of-line inspection or at the customer’s facility
Recurring manual intervention to re-label parts
Hidden costs reaching up to €20,000 per year in consumables and maintenance

FIT Laser Marking: A Consumable-Free Solution for Body in White Lines

SIC Marking developed the FIT (Flexible Integrated Technology) system specifically for BIW constraints. The laser mark is applied directly to the metal part – no contact, no consumables, no label.
