Precision Medical Identification

Cleaner marks for medical-grade identification

Precision Medical Identification Laser Flow Labs provides precision marking designed for medical-grade identification and high-cleanliness requirements. Capabilities commonly requested: • UDI-ready Data Matrix marking • Serial, lot, and traceability marking • Part marking that prioritizes cleanability and low surface disruption • Process development to hit your contrast + readability

Laser Annealing vs. Laser Etching Why medical teams choose annealing In medical environments, surface texture matters. Deep or rough marks can collect residues. • Reduced pitting / fewer contaminant traps • Easier cleaning and inspection • Consistent, readable identification What is laser annealing? Uses a laser to heat the surface to create a high-contrast mark without cutting into the material. • Minimal to no material removal • Smooth surface profile • Reduced risk of pits What is laser etching? Creates a mark by removing material (ablation or melting), leaving a textured mark with depth. • Creates surface texture • Can introduce micro-pitting • Texture may trap residues Simple rule: Annealing = Smooth surface. Etching = Removed material (texture).

Quick FAQ Will annealed marks wear off? Annealed marks are designed for durability under normal handling and cleaning. For extreme abrasion environments, etching may be considered - with cleanability tradeoffs. Can you mark on curved or small parts? Yes. We tune the process for curvature, surface finish, and code size to keep scan performance strong. What affects contrast the most? Material alloy, surface finish (polished vs. bead-blasted), and process settings. We validate contrast on your actual part condition.
