ProtoBatch CNC integrates advanced fiber and UV laser technology to deliver high-contrast, permanent marks that enhance both functionality and brand value. Discover how our solutions can upgrade your part identification today.
Specialized Laser Marking Processes: Engraving, Etching & Annealing
Deep Laser Engraving
For maximum durability in harsh environments, we utilize high-energy beams to vaporize material, creating physical depth (0.1mm - 0.5mm). Ideal for VIN codes, serial numbers, and molds that must remain legible after secondary coating or extreme abrasive wear.
High-Contrast Laser Etching
Our high-speed etching process melts the material surface to produce high-contrast marks without compromising structural integrity. This is the preferred solution for complex brand logos, 2D Data Matrix codes, and QR codes on anodized aluminum and plastics.
Medical-Grade Laser Annealing
Specifically for stainless steel and titanium, annealing uses controlled heat to induce oxidation, creating a permanent black mark. This non-ablative process maintains a perfectly smooth surface, preventing bacterial growth and corrosion in medical device applications.

Laser Marking & Part Traceability FAQ
Is laser marking truly permanent for industrial parts?
Yes. Unlike labels or inkjet, laser marking physically alters the material surface through engraving or annealing, providing indestructible traceability that resists chemicals, abrasion, and extreme temperatures.
Can you mark logos or serial numbers on curved surfaces?
Absolutely. Utilizing our 4-axis rotary attachments, we provide 360° continuous marking on cylindrical components such as shafts, connectors, and tubes without any pattern distortion.
Does laser marking damage the surface of medical devices?
We use specialized laser annealing for medical and aerospace parts. This process creates high-contrast marks via heat-induced oxidation without removing material, preserving corrosion resistance and surface integrity.
What file formats are required for custom branding?
For the sharpest results, we prefer vector files (DXF, AI, or EPS). For UID codes and sequential serialization, we can import variable data directly from your CSV or Excel spreadsheets. For more information, visit our about page.
