Permanent laser marks on the parts the world depends on.

Contract laser marking for medical devices, aerospace components, and precision industrial parts. Annealing, deep engraving, etching, and color marking — to your print, in batches from one to one million.

Parts we marked this quarter.

Full capabilities

Built for parts that can't be re-marked.

When a part fails traceability, it gets scrapped. We mark to your spec the first time — clean, in-tolerance, and documented for audit.

HIGH MIX · LOW MIN

Four ways to put a permanent mark on metal or plastic.

Each process leaves a different signature. We help you pick the one that meets your specification, surface, and downstream process — passivation, anodizing, sterilization, you name it.

Annealing

PROC · 01

A subsurface oxide layer formed by controlled heat. No material is removed — the surface stays smooth, passivates normally, and survives autoclave cycling. The gold standard for surgical instruments.

  • Best onTitanium · stainless · cobalt-chrome
  • Depth0 µm (subsurface)
  • SurvivesPassivation · autoclave · gamma

Deep Engraving

PROC · 02

Material removed in successive passes — typical depths 0.001″ to 0.030″. Reads after paint, after sandblast, after coating. Used for MIL-STD IUID plates, tool numbers, and part marks meant to outlive the part's surface treatment.

  • Depth0.001″ – 0.030″
  • Smallest char0.020″ readable
  • Passes5–80, automatic

Surface Etching

PROC · 03

A shallow, high-contrast frost on the surface. Faster than engraving, cleaner than annealing on alloys that don't anneal well (300-series at low power). Ideal for logos, asset tags, and high-volume cosmetic marks.

  • Depth≤ 0.0005″
  • Throughput~2,400 parts/hr
  • LookMatte white frost

Color Marking

PROC · 04

On titanium, controlled oxide thickness produces real colors — gold, purple, blue, green — without inks or dyes. On engineering plastics, we run carbon-black, red, and green foaming marks on white ABS and PEEK.

  • Ti paletteGold · bronze · purple · blue · cyan
  • Plastic paletteBlack · red · green on white
  • InksNone — purely thermal

Quality record

Marking is the part of the process where great parts get scrapped. We don't scrap parts.

"

We switched our UDI direct part marking to LaserFlow after a competing shop's annealed mark failed crevice-corrosion testing. Fourteen months later, zero rejected lots and our auditor stopped asking about it.

"

First-article photos with the parameter log in the email, every single lot. I never have to chase them for documentation. That's the difference between a vendor and a partner.

"

An engineer reads our prints and flags issues before we run. The cost of one re-mark cycle on a 100k-unit lot is what pays for everything else.

We do more than mark.

A few adjacent services we run in-house so you can hand off a finished, traceable part instead of routing it through three vendors.

ADJ · 01

Passivation

Nitric or citric passivation per ASTM A967 / AMS 2700, with first-article test coupon. Required after annealing on most surgical instruments.

ADJ · 02

Laser Ablation

Selective coating, paint, or anodize removal — clean fiducials, contact points, ground pads. Replaces hand-masking and scraping.

ADJ · 03

Kitting & Assembly

Bagging, labeling, and drop-shipping straight to your customer. PPAP-ready packaging, MIL-STD-2073 codes available.

ADJ · 04

Custom Fixturing

3D-printed and machined fixtures designed in-house. Most fixtures amortize into per-part pricing after the first run.

Audit-ready, by default.

Every job ships with traceability documentation: drawing revision, machine ID, operator initials, mark-cycle parameters, and a sample first-article photo. If your customer needs PPAP, FAI, or DHF support, the data is already there.
