White paper for production managers in medical technology: reliable UDI marking, resilient processes, fewer rejects
UDI markings on surgical steels must remain clearly legible and corrosion-free even after hundreds of cleaning and sterilisation cycles. The white paper shows how you can integrate black marking with ultrashort pulse lasers into series production with process reliability and so ensure long-term traceability. Technical background information, optimal parameter ranges and proven post-treatment concepts will help you design robust marking processes.
- Translate requirements from UDI and everyday clinical practice into specific process criteria
- Evaluate suitable steels, pre-treatments and their influence on corrosion and acid resistance
- Define laser parameters (pulse energy, scan speed, focus position) for high-contrast, permanent black markings
- Understand the role of LIPSS nanostructures for readability, contrast and viewing angle independence
- Select passivation and cleaning strategies that increase corrosion protection without weakening the marking
