Aerospace Thermoforming Manufacturer for Cabin Interiors and Equipment Fairings

Aerospace cabin parts have to pass FAR 25.853 burn tests, smoke density requirements (BSS 7239), and OSU heat-release testing — and every certificate has to be traceable to the sheet stock that made the part. We’ve been making aerospace-grade thermoformed components since the late 1990s, with material traceability and burn-certificate pass-through built into our production.

FAR 25.853 / 25.855 Boltaron and Kydex grades · BSS 7239 smoke density compliant materials · IATF 16949 certified factory · Material certs with full traceability · Mutual NDA before review

What we make for aerospace OEMs and Tier-1s

• Cabin sidewall panels — large-format, FAR 25.853-compliant
• Equipment fairings — overhead bin internal trim, lavatory components, galley wall panels
• Seat-back monitors and bezels — ABS/PC blends with anti-glare finishes
• Instrument fairings — flight-deck fascia and instrument-panel surrounds
• Aircraft interior covers — service panel covers, electrical box covers, lavatory door panels
• Ground support equipment housings — non-flight components for ground service vehicles, ramps, baggage handling
• Mass transit / rail interiors — closely related: train interiors, metro car panels using FAR-equivalent materials

We don’t make structural primary or secondary aircraft components (those require AS9100 certification and aerospace-specific quality systems we don’t currently hold). For interior trim, fairings, and non-structural cabin components, our IATF 16949 + ISO 9001 quality system + material traceability is sufficient for most Tier-1 aerospace interior suppliers.

Aerospace material grades we form

Material	Compliance	Typical use
Boltaron 4335	FAR 25.853, BSS 7239, OSU	Cabin sidewall, ceiling panels
Boltaron 9805	FAR 25.853 (a)(1)(i), BSS 7239	Galley and lavatory panels
Kydex 100	FAR 25.853 vertical burn	Seat-back panels, instrument fairings
Kydex T	FAR 25.853, BSS 7239, low-smoke	Cabin trim, overhead components
Boltaron 4332 EX	OSU heat release ≤65/65	Premium-cabin interior parts
PC blends with FR additives	UL 94 V-0, FAR 25.853 vertical burn	Electrical box covers
PETG (FR grade)	FAR 25.853 vertical burn	Transparent panels, light fixtures

For each project, the material certificate (COA) and burn test report are pass-through documentation from the mill — Boltaron, Sekisui (Kydex), or equivalent. We provide the chain-of-custody from mill lot to finished part.

Why thermoforming for aerospace interiors

Weight savings: Thermoplastic interior components are typically 40–60% lighter than equivalent fiberglass-reinforced parts. For an aircraft program, every kilogram on a single seat means thousands of kilograms of fuel saved over the airframe’s service life.

Cost vs. composite layup: Hand-laid composites for aerospace interiors run $200–$800/part labor cost. Thermoforming is $20–$100/part for similar geometry. The trade-off is structural performance — for non-structural interior trim, thermoforming wins decisively.

Lead time vs. injection molding: Tooling for aerospace interior parts is typically 4–8 weeks at injection molders. We deliver tools in 2–3 weeks. For a program with tight certification timelines, this can be the difference between a Q3 and Q4 program launch.

Material flexibility for certification: During DER (Designated Engineering Representative) review, you may need to validate the same geometry in two different material grades. With thermoforming tooling, that’s a sheet swap. With injection, it’s two tools or extensive process validation.

Aerospace project workflow

Step 1 — NDA and material specification (1–3 days)

Mutual NDA. Material specification confirmed: Boltaron grade, Kydex grade, or alternative. Burn test certification level required (FAR 25.853 (a)(1)(i) vs (a)(1)(ii) etc.).

Step 2 — DFM review (24–48 hours)

Our engineering team reviews STEP file. For aerospace interior parts we specifically check:

• Draft angles — minimum 3° on flame-test surfaces (sharp corners can fail vertical burn even with FR-grade material)
• Wall thickness uniformity — affects flame propagation rate; we model expected wall thickness distribution
• Mounting interfaces — clip features, fastener bosses; aerospace clip designs are specific
• Surface texture — leather grain matching customer reference samples
• Material change feasibility — if geometry validates in Boltaron 4335 but program later switches to Boltaron 9805, no tooling change needed

Step 3 — Tooling and first article (3–4 weeks)

Block aluminum tool with acid-etched texture if Class A finish required. First article shipped with FAI report and material certificate.

Step 4 — Burn test certification (1–3 weeks, depends on test lab)

• We don’t run burn tests in-house. We coordinate with customer’s preferred test lab (or recommend Element, NIAR, or ISP Plastics Lab).
• Test specimens cut from production-equivalent forming runs.
• Test report flows to customer; we keep copy in production batch records.

Step 5 — Series production with traceability

• Each production batch ties to mill lot of incoming sheet stock
• Burn-test certificate from current mill lot pulled and packaged with COA on every shipment
• Production records retained 7 years (FAA standard)

Aerospace-specific quality controls

Material lot quarantine: Incoming sheet stock held in dedicated quarantine area until COA + burn test certificate verified against material specification.

Production traceability: Every part stamped or labeled with lot code. ERP records sheet lot, machine, operator, shift, date.

First-piece inspection per shift: On aerospace programs, first piece inspected before production proceeds. Our standard.

Non-conformance escalation: Aerospace customers are alerted within 24 hours of any non-conformance discovery. 8D root-cause within 7 working days.

Production records retention: 7 years standard (some customers request 10).

Engineering change control: No process change without customer notification + sign-off (PCN process).

What we do NOT do for aerospace

We’re explicit because mismatches waste your time:

• ❌ AS9100 certified production (we have ISO 9001 + IATF 16949; AS9100 audit not yet completed)
• ❌ Structural primary or secondary aircraft components
• ❌ Composite layup or autoclave-cured parts
• ❌ Burn testing in-house (subcontracted)
• ❌ Cleanroom-class manufacturing
• ❌ DER engineering services (you provide DER on your side)

If your program requires any of the above, talk to a specialist supplier. For everything else — interior trim, fairings, equipment housings — we have 25+ years of relevant experience.

Frequently asked questions

Are you AS9100 certified?

Not yet. We have ISO 9001:2015, ISO 14001, ISO 45001, IATF 16949:2016. AS9100 certification audit is on our 2026 roadmap but not complete. For aerospace interior trim and non-structural fairings, our current certifications are sufficient for most Tier-1 suppliers. For flight-critical structural parts, you need AS9100-certified.

Can you do prototypes for DER review?

Yes. Single-piece prototypes on MDF tooling from $300–$2,000. Shipped in 5–10 working days. Full burn-test certificate-grade material if you need certification-equivalent samples.

What lead time for typical aerospace tooling?

Tool: 3 weeks for block aluminum. First article: 1 week after tool. Burn test certification: 2–3 weeks at test lab (lab queue dependent).

Do you handle anti-microbial finishes for cabin parts?

Yes — silver-ion infused FR-grade material grades available. Verified by ISO 22196 testing if required.

What’s your minimum order for aerospace?

1 piece for prototypes. Production minimum typically 50–500 units for cost efficiency. Above that, per-piece pricing scales linearly.

Do you ship to USA / EU?

Yes — DDP terms common with aerospace customers (we handle import compliance). Sea freight 25–35 days to US East Coast / EU; air freight option for AOG (aircraft on ground) urgencies.
