- Food-grade stainless

Every material has a tuned parameter set. Every mark type has a purpose. This page is the short version of our lab notebook — what we run, what it’s for, and what it lives on. Every serialized mark is scanned and checked against its data before shipment.
Oxide-layer marking for medical-grade stainless. Rust-proof, passivation-friendly, no material removal.

Dark, high-contrast marks on anodized aluminum and coated substrates. Crisp legibility at small scales.

High-density 2D Data Matrix and QR codes, 100% verified. UID-ready for MIL-STD-130 programs.

Variable-depth, multi-pass engraving for mold cavities, tooling IDs, and stepped tool features. Recessed marks that survive heat treat, regrinding, and heavy handling.

Laser-bleached white-on-black marks on tesa 6973 and 3M 7847 dual-layer acrylate film — tamper-evident, UV-stable label stocks engineered to replace etched metal plates on hardware that can’t take a direct mark. Both fragment on removal and resist chemicals and abrasion to +392°F; tesa 6973 is rated down to −58°F.

IUID labels laser-marked on 3M 7847 and tesa 6973 acrylate label stock. ECC 200 Data Matrix in the ISO/IEC 15434 envelope: Format 06 data identifiers or Format 12 ATA Spec 2000 text element identifiers, Construct 1 or 2. Every symbol read back against its data before shipment.

Identification labels for unit packs and exterior shipping containers to MIL-STD-129R. PDF417 barcode per Appendix A, Table A-IV, carrying contract number, CLIN, shipment number, CAGE, part number, quantity, serials, and UIIs, with the human-readable lines beside it. Thermal-transfer printed on paper stock with permanent acrylic adhesive, scan-checked, shipped with a Certificate of Conformance.

316L stainless data plates for pressure equipment — repair and alteration nameplates, vessel and boiler data plates, and replacement plates. Laser-annealed rather than etched, so no metal is removed and the plate keeps its corrosion resistance. Laid out to the code figure the job is filed under, proofed before the cut.

Laser-annealed 316L stainless nameplates, rating plates, and asset tags for equipment in marine, outdoor, washdown, and engine-bay service: OSHA and NEC rating plates, USCG capacity and HIN plates, SOLAS equipment plates, EPA emission labels in metal, and serialized stainless asset tags. Marked to your drawing or the applicable rule and proofed before the cut.

Short-run valve tags, legend plates for 22 mm and 30 mm operators, electrical panel and disconnect tags, equipment and HVAC unit tags, cable tags, and tool tags in anodized aluminum, 304/316 stainless, or brass. No minimum order and no setup fee; each tag carries its own text from your list, proofed before marking.

The list below covers our common substrates. If your material isn’t here, ask — most metals and engineering plastics are within range.
Plastics are grade-dependent: resin, colorant, and filler decide whether the mark comes out dark or light and how well a Data Matrix reads. The material marking guide covers process and contrast per material, and the materials pages go deeper on stainless, aluminum, titanium, and plastics.
