We provide AS478 Compliant Parking Marking in a variety of methods.

What is AS478 Part Marking?

AS478 is the aerospace industry standard for part identification marking. It defines the methods, durability, and legibility requirements for applying permanent identification to aerospace components. Proper marking ensures traceability, quality compliance, and customer confidence throughout the entire lifecycle of a part.

Why Part Marking Matters in Aerospace Manufacturing

In aerospace, every part must be traceable. Marking provides:

  • Identification – ensuring the correct part is used in assemblies.

  • Traceability – linking parts back to material certifications, inspection records, and manufacturing orders.

  • Compliance – meeting AS9100, customer, and regulatory requirements.

  • Durability – markings must remain legible through processing, coatings, and long service life.

Our Part Marking Capabilities

We perform AS478-compliant part marking with methods selected based on part geometry, material, and customer requirements:.  Here are a few that you can contact us about today.

  • Mechanical Engraving (AS478 Method 3A) – precision machine engraving for permanent, durable markings.

  • Electrochemical Etch Marking (AS478 Method 3B) – non-stress, high-contrast marks ideal for aerospace alloys.

  • Laser Marking (AS478 Method 15) – precise, permanent marks suitable for metals and coated surfaces.

  • Ink & Paint Fill (AS478 Method 13) – for temporary or supplemental identification where permanent marking is not required.

Human-Readable & Machine-Readable Marking

Depending on customer requirements, we can apply markings in:

  • Human-Readable Format – clear alphanumeric text for visual identification.

  • Machine-Readable Format – Data Matrix codes, barcodes, or other scannable symbologies to enable automated traceability and digital recordkeeping.

  • Combination Marking – both formats applied together, ensuring compliance with AS478 while also supporting modern MRP/ERP and aerospace traceability systems.

All marking processes are validated to ensure legibility, permanence, and compliance with AS478 and customer specifications.
