How the Surface Enhancement Process Works

Step 1 — Part Evaluation & Process Selection

Material type, geometry, and specification requirements determine the appropriate enhancement method.

Step 2 — Masking & Fixturing

Critical surfaces are protected using custom masking and precision fixturing for consistent results.

Step 3 — Controlled Surface Processing

Parts undergo tightly controlled peening or blasting using calibrated parameters for pressure, media, exposure, and coverage.

Step 4 — Verification & Post-Process Inspection

Coverage, surface condition, and specification adherence are validated for compliance and repeatability.

Why Work With MIL for Surface Enhancement?

NADCAP-Accredited, Specification-Driven Processes

FAQs

MIL supports a wide range of prime-approved shot peening and surface enhancement specifications, including common requirements from major aerospace OEMs. Our processes align with:

  • AMS 2430 / AMS 2432
  • MIL-S-13165 (legacy requirements)
  • Customer- and prime-specific intensity, coverage, and masking standards
  • NADCAP-controlled process documentation

If you provide a drawing or specification, our team can confirm approval status and compliance before processing.

Typical turnaround times are:

  • Standard jobs: 3–5 business days
  • Complex geometries / heavy masking: 5–10 business days
  • High-volume or repeat production: Scheduled for predictable weekly release
  • Urgent prototype or AOG work: Expedited slots often available

Turnaround may vary based on masking complexity, media changes, or required downstream finishing.

MIL maintains strict control over shot type, intensity, and coverage using robotic systems and calibrated equipment.
Capabilities include:

  • Media Types: Steel shot, glass bead, ceramic bead (others available per spec)
  • Intensity Range: Typically 0.003–0.024 A/N Almen depending on specification
  • Coverage:
    • Standard: 100% coverage
    • High-reliability applications: 150–200% coverage (per print or prime requirement)

Robotic peening enables tight repeatability on complex shapes, small radii, and mixed contour parts.

Yes. MIL performs:

  • In-house Almen strip measurement
  • Full saturation curve development and verification
  • Routine intensity checks
  • Media size, shape, and flow-rate monitoring

All results are documented and included as part of NADCAP-compliant process control.

In many cases, yes—with proper evaluation and masking.
We regularly peen components that are:

  • Anodized
  • Chem-filmed
  • IVD aluminum coated
  • Primed or partially coated

Our masking specialists use custom fixtures, elastomeric masks, and part-specific tooling to protect critical finishes while still achieving required intensity and coverage.

Typical capabilities include:

  • Shot Peening (Robotic): Medium-sized components up to ~550 lbs
  • Abrasive Blasting: Parts up to ~11 ft long × 3 ft wide in our manual cabinets
  • Precision / Pencil Blasting: Small, intricate components requiring high accuracy

If your part falls outside these ranges, we can review drawings to determine feasibility.

MIL performs standard shot peening process verification in-house; however:

  • Fatigue-life testing and
  • Residual-stress XRD (X-ray diffraction)

Can be arranged through qualified external laboratories when required by the specification or program.
We coordinate coupon preparation, testing, and reporting for full traceability.
