Aerospace Forging Companies in India: How to Evaluate and Select a Qualified Supplier

Knowledge Base

April 13, 2026

Evaluating aerospace forging companies in India requires a structured approach that goes well beyond comparing quotations or verifying that a supplier holds an AS9100D certificate. Aerospace forging is a regulated supply chain activity where the consequences of supplier failure — a grounded aircraft, a safety incident, an airworthiness authority investigation — are qualitatively different from a commercial quality problem. The evaluation criteria that matter are largely invisible in a brochure and only become clear through direct technical assessment and production record review.

The Evaluation Framework: Five Levels

Experienced aerospace procurement teams in India — at HAL, Safran India, GE India, Airbus India — use a consistent framework for evaluating forging suppliers regardless of the specific component category. Understanding this framework from the supplier perspective helps both buyers accelerate evaluation and suppliers prepare more effectively.

Level 1: Certification Verification

AS9100D is the mandatory entry gate. Verify:

Current certificate — check the expiry date. Request the certificate, not a photocopy of a historical certificate.
IAQG-recognised certification body — verify in the OASIS database (iaqg.org/oasis). Takes two minutes. Certification bodies not in IAQG’s recognised list are not acceptable for aerospace programmes regardless of their general quality reputation.
Scope statement — read every word. “Design and manufacture of closed die forgings” does not cover open die forging, ring rolling, heat treatment, NDT, or machining even if all are performed at the same facility. The scope must explicitly cover all processes the supplier will perform for the programme.
Facilities covered — a certificate covering one facility does not extend to a second facility under the same company name.

NABL accreditation — verify that the test lab performing mechanical and chemical testing is NABL-accredited and that the accreditation covers the specific tests required (tensile, Charpy, hardness, OES chemical analysis).

NADCAP — not a routine requirement for Indian DPSU aerospace programmes but increasingly required for international OEM offset supply. If the programme is from an international prime, check whether NADCAP for heat treatment and NDT is required.

Level 2: Process Capability Assessment

Capability claims require evidence. The standard documentation request for Level 2 assessment:

Recent material test reports — from production in the same material grade (Ti-6Al-4V, Inconel 718, 7075, 4340) and similar weight range as the programme requirement. Not capability statements — actual production records. A supplier claiming titanium forging capability who cannot produce a recent titanium MTR has not actually forged titanium recently.

Equipment list with specifications — press capacity (tonnes), hammer energy (kJ), furnace temperature range and working zone dimensions, ring mill specifications (max diameter, max height), NDT equipment list with frequencies and calibration standards.

In-house versus outsourced operations — the single most important question. Heat treatment, NDT, and machining must be in-house for aerospace programmes. Outsourced special processes require the OEM to audit the subcontractor separately — which most aerospace OEM supplier quality teams will decline to do for a new supplier qualification.

Weight and dimensional evidence — a supplier claiming 5–1,400 kg closed die range should be able to show a recent production record of a 1,200 kg forging. Capability ranges stated without evidence are treated as marketing claims.

Level 3: Quality System Maturity

Non-conformance log review — a well-functioning aerospace quality system has a well-populated NCR log. An empty or near-empty NCR log in a forging facility is a red flag — it indicates non-conformances are not being formally recorded. Request to review the last 12 months of NCR log entries and a sample of closed corrective actions.

Corrective action quality — examine three to five corrective actions from initiation through close. Shallow root cause analysis (“operator error — retrained”) is a sign of a superficial quality culture. Genuine root cause analysis identifies the systemic cause and implements a process change.

Internal audit programme — is it running on schedule? Are audit findings being closed? Request the last internal audit report and status of findings. A supplier who cannot produce these within 24 hours does not have a functioning internal audit system.

First article experience — has the supplier submitted AS9102 FAIRs to aerospace customers? Ask for an example FAIR package from a previous programme. The quality and completeness of this package tells you what your FAIR package will look like.

Level 4: Technical Depth Assessment

Technical depth assessment goes beyond process records to evaluate whether the supplier’s engineering team genuinely understands the aerospace forging requirements — not just meets them on paper.

Grain flow understanding — can the supplier explain how their die design for a recent forging orients grain flow to the principal stress direction? Can they show the forging flow analysis (simulation or empirical) that supports the die design? A supplier who cannot articulate grain flow design is not operating at aerospace forging technical depth.

Material-specific process knowledge — ask a material-specific question for each grade the supplier claims capability in. For titanium: how is alpha case controlled and verified? For Inconel 718: what is the beta transus analogue for Inconel and why does the delta phase matter? For aluminium 7075: what is the maximum quench delay and why? Correct, specific, confident answers indicate genuine process knowledge. Vague or evasive answers indicate claimed capability without supporting knowledge.

FAIR process understanding — ask the quality team to walk through how they would assemble an AS9102 FAIR package for a new aerospace forging. Which forms are required? How are key characteristics identified and documented? What supporting records are attached? Suppliers who have completed aerospace FAIRs know this process in detail — those who claim aerospace capability without FAIR experience do not.

Level 5: Organisational Reliability

Management and ownership stability — how long has the management team been in place? Is the quality director who will pass the AS9100D audit the same person likely to be there in five years? For aerospace programmes with 10–20 year supply relationships, management continuity is a supply chain risk.

Capacity headroom — what is current capacity utilisation? A supplier at 95% capacity cannot absorb urgent orders, schedule changes, or reject-and-replace situations without programme disruption.

Key person dependency — is the titanium forging process knowledge held by one person who has been there 20 years? What happens if that person leaves? Institutional knowledge must be in documented procedures, not individual heads.

Red Flags Specific to Aerospace Forging Evaluation

Outsourced heat treatment or NDT — immediately reduces qualification probability. Most aerospace OEM supplier quality teams will not accept outsourced special processes for new suppliers. The additional subcontractor audit requirement makes qualification impractical.

No previous FAIR submission experience — a supplier who has never completed an AS9102 FAIR will require significant learning time during qualification. The first article stage will take longer and the probability of FAIR rejection for documentation issues is high.

Claiming material capability without evidence — titanium and Inconel capability claims without supporting recent production records. These materials require specific process knowledge, equipment, and furnace capability that cannot be improvised. If the supplier cannot produce an MTR from recent titanium production, they have not recently forged titanium.

AS9100D certificate with narrow scope — “forging only” with heat treatment and NDT outsourced. This is not an aerospace forge-to-finish supplier — it is an aerospace forger dependent on subcontractors for its most critical quality-determining operations.

Inability to name the IAQG OASIS database — if a supplier claims AS9100D certification but does not know that IAQG maintains a public database where their certification can be verified, the quality team is not deeply engaged with the aerospace quality standards ecosystem.

No capability to discuss AMS specifications — AMS 4928 for titanium, AMS 5663 for Inconel 718, AMS 4126 for aluminium 7075. These are the material specifications for aerospace forging. A supplier who cannot immediately identify which AMS applies to their claimed material capability is not operating as an aerospace forging supplier.

The Indian Aerospace Forging Supplier Landscape

Understanding who is actually qualified and operating in the Indian aerospace forging market — versus who claims to be — helps buyers set appropriate expectations.

Tier 1: Full-Capability Multi-Material Aerospace Forging Suppliers

AS9100D certified with aerospace-specific scope, all processes in-house, NABL-accredited testing, capability across titanium, Inconel, aluminium, and alloy steel, previous FAIR submission experience, HAL or equivalent OEM qualified. This is a small group — fewer than 10 companies in India operate at this level across the full material and process range.

Tier 2: AS9100D Certified Single-Material or Single-Process Specialists

AS9100D certified with scope covering one or two material families, all or most processes in-house, some aerospace production history but not across the full material range. May be titanium specialists or aluminium specialists but not multi-material. Suitable for well-defined single-material programmes.

Tier 3: Defence Forging Suppliers with Aerospace Aspiration

AS9100D certified for defence supply (Army, Navy, missiles) but without previous aerospace OEM qualification. Quality system is in place, capability may be adequate, but the aerospace-specific process knowledge gaps (alpha case control, beta transus testing, AS9102 FAIR process) have not been developed. Require 12–18 months of additional preparation before approaching aerospace OEM qualification.

Tier 4: General Industrial Forging Manufacturers

ISO 9001 certified, serving commercial markets, occasional defence supply. Not AS9100D certified. Not appropriate for primary aerospace supply chain regardless of forging technical capability. Cannot satisfy airworthiness traceability requirements.

Frequently Asked Questions — Aerospace Forging Companies India

How many AS9100D certified aerospace forging companies are there in India?
Estimates vary but the number of Indian forging manufacturers with current AS9100D certification scoped to include aerospace-relevant processes — titanium, Inconel, or aluminium forging with in-house heat treatment and NDT — is fewer than 15 companies. The number with demonstrated production history across multiple aerospace material families (titanium, Inconel, and aluminium) is considerably smaller — fewer than five by most assessments. The number with NADCAP in addition to AS9100D is currently very small — this is an emerging area as Indian suppliers target international aerospace OEM supply.

What is the OASIS database and how does a buyer use it to verify AS9100D certification?
OASIS (Online Aerospace Supplier Information System) is the IAQG’s public database of AS9100D certified organisations. It is accessible at iaqg.org/oasis. Buyers search by company name or CAGE code. The result shows the current certification status, the certification body name, the scope of certification, and the next surveillance or recertification date. Any supplier claiming AS9100D certification should be immediately searchable in OASIS. A company that appears in OASIS with a current certificate and an appropriate scope is certified. One that does not appear, appears with an expired certificate, or appears with a scope that does not cover the required processes is not appropriately certified for the programme.

Should aerospace buyers prefer large or small Indian forging companies?
Size is not the primary evaluation criterion for aerospace forging. A mid-sized Indian forging manufacturer with deep titanium and Inconel process expertise, 15+ years of aerospace production history, and a well-maintained AS9100D quality system is a lower-risk supplier than a large company with broader capacity but limited aerospace-specific process experience. The key factors are material-specific process knowledge, in-house special process coverage, quality system maturity, and production history depth in the relevant material and weight range.

What does it mean when a supplier says they are “aerospace approved” without specifying the approving OEM?
“Aerospace approved” without specifying the OEM, the component family, and the material grade is a marketing claim without quantifiable meaning. Aerospace approval is component-specific, material-specific, and OEM-specific. A supplier approved by HAL for titanium airframe forgings is not automatically approved for Inconel engine forgings or for a different OEM’s programme. Buyers should ask specifically: approved by whom, for what component family, in what material, at what facility, and when was the last surveillance audit? If these questions cannot be answered specifically, the approval claim cannot be relied upon.

What is the minimum production history a supplier should have before being considered for an aerospace forging programme?
Aerospace OEMs use informal benchmarks: three years of production history in the relevant material and process family is the minimum for initial qualification credibility. Five or more years significantly reduces risk profile. Ten or more years with consistent quality metrics and sustained OEM relationships is the profile of a low-risk, long-term aerospace forging supplier. Suppliers with less than two years of production history in the required material — even with valid AS9100D certification — are typically not considered for primary structural aerospace components on the grounds that production history is too limited to evidence process stability.
