Our Precision Investment Casting Capabilities
As India’s premier precision investment casting manufacturer, Uni Tritech operates a NADCAP-certified, AS9100D-qualified foundry built to produce complex, near-net-shape castings that meet the most stringent dimensional, metallurgical, and surface integrity requirements of global aerospace and defence OEMs:
- Tight Dimensional Tolerance: ±0.1 mm on critical features; CT4–CT6 per ISO 8062 as standard across all alloy families.
- Complex Geometry Capability: undercuts, thin walls from 1.0 mm, compound curves, internal passages, and aerofoil profiles — all achievable in a single casting.
- Full Alloy Range: nickel superalloys (Inconel 718, IN713C, IN939), titanium (Ti-6Al-4V), stainless (316L, 17-4PH, duplex 2205), aluminium (A356, A357), and cobalt alloys.
- Surface Finish: Ra 1.6 to 6.3 µm as-cast standard; post-cast polishing and machining to Ra 0.4 µm achievable.
- NADCAP Special Processes: Heat Treatment, NDT, Welding, and Chemical Processing all accredited — 100% X-ray and FPI on all aerospace castings.
- First Article Inspection: AS9102-compliant FAIR with CMM dimensional report, NDT records, material certificates, and full traceability documentation.
Precision Investment Casting Process at Uni Tritech
Our precision investment casting manufacturer process is engineered for right-first-time quality — combining simulation-verified gating design, NADCAP-accredited special processes, and 100% inspection at every critical stage:
- CAD & DFM Review: every casting begins with a complimentary DFM review — identifying castability risks, wall thickness violations, and tolerance mismatches before tooling investment.
- Precision Wax Die Fabrication: wax injection dies machined to ±0.025 mm producing wax patterns that transfer dimensional accuracy to the finished casting.
- Ceramic Shell Building: 6 to 12-layer refractory shell built to the specific alloy and geometry — primary coat in zirconia or alumina for fine surface detail.
- Vacuum Induction Melting: all reactive alloys (nickel superalloys, titanium, cobalt) melted under vacuum — eliminating oxide inclusions critical for fatigue-loaded aerospace castings.
- NADCAP Heat Treatment: every casting thermally processed under NADCAP-accredited conditions — AMS 2750 pyrometry, time-temperature records, and witness samples on every cycle.
- 100% NDT & CMM Inspection: X-ray per ASTM E192/E155, FPI per ASTM E1417, and CMM dimensional verification against 3D model — before any casting leaves our facility.
Why Choose Uni Tritech as Your Precision Investment Casting Manufacturer?
Global aerospace procurement teams choose Uni Tritech as their precision investment casting manufacturer in India because we are the only Indian foundry that combines the full aerospace quality credential stack — NADCAP across four scopes, Airbus and Collins Aerospace approval, AS9100D, and proven active supply to international prime contractors — with competitive Indian manufacturing cost.
Our precision investment casting capability is not a claim — it is verified by Airbus, Collins Aerospace, Safran, HAL, and ISRO through active supply relationships and ongoing supplier quality audits. Choose Uni Tritech and eliminate the quality risk that comes with uncertified casting suppliers.
- NADCAP ×4 Scopes: the only investment casting foundry in Karnataka with NADCAP accreditation for NDT, Heat Treatment, Welding, and Chemical Processing simultaneously.
- India's First Airbus-Approved Foundry: Airbus SQIP qualification accepted globally — your Airbus supply chain starts with a qualified Indian source.
- Collins Aerospace Approved: direct qualification accepted by Collins Aerospace for precision investment casting of engine and structural components.
- Active Supply to Global Primes: Safran, HAL, ISRO, Magellan Aerospace — named, verifiable, current supply relationships not historical references.
- Competitive Indian Cost: NADCAP-certified precision casting at 30 to 50% lower total cost than equivalent European or US foundries — verified by customers who have made the transition.
Key Precision Investment Castings Manufactured by Uni Tritech
As a full-capability precision investment casting manufacturer, Uni Tritech produces critical components across the aerospace, defence, space, and medical sectors:

- Structural Aerospace Castings: titanium Ti-6Al-4V and aluminium 7075 structural fittings, brackets, and frames for aircraft primary structure.
- Landing Gear Components: 300M and 15-5PH high-strength steel castings for aircraft undercarriage with full fatigue life documentation.
- Medical & Implant Components: cobalt-chrome (ASTM F75) and titanium (Ti-6Al-4V ELI) biocompatible castings for surgical instruments and orthopaedic implants.
- Rocket & Space Components: Inconel 718 turbopump components, cryogenic valve bodies, and satellite structural castings for ISRO and NewSpace customers.
- Defence & Armament Parts: precision castings for guided weapon systems, armoured vehicle components, and naval hardware under strict traceability and NDA.
Commitment to Precision Casting Quality
At Uni Tritech, quality is not a department — it is the operating philosophy of every person in the foundry. Our precision investment casting quality system is built on four pillars:
- NADCAP-Accredited Special Processes: every heat treatment cycle, NDT inspection, weld repair, and chemical treatment is performed under PRI-audited, prime contractor-approved procedures.
- 100% First-Piece Inspection: no casting is shipped without CMM dimensional verification, X-ray, FPI, and chemical composition confirmation on the melt heat.
- Full Material Traceability: heat number, alloy certification, casting record, heat treatment record, and NDT report maintained for every casting — full birth record documentation.
- Continuous Improvement Culture: internal audit programme, SPC on key process parameters, and customer escapes driving systematic CAPA — not just corrective action on individual failures.

Frequently Asked Questions
Uni Tritech is a precision investment casting manufacturer because of its combination of tight tolerance capability (±0.1 mm), NADCAP accreditation across four scopes, Airbus and Collins Aerospace approval, vacuum induction melting for reactive alloys, 100% NDT on all aerospace castings, and active supply to global prime contractors including Safran, HAL, and ISRO. These credentials are independently verified — not self-declared.
Uni Tritech’s precision investment casting achieves ±0.1 mm on critical small features and ±0.3 mm on medium-sized features — equivalent to Casting Tolerance Grade CT4 to CT6 per ISO 8062. As-cast surface finish is typically Ra 1.6 to 6.3 µm. These tolerances frequently eliminate secondary machining requirements on non-functional surfaces, reducing total component cost versus less accurate casting processes.
Uni Tritech casts all major aerospace and precision engineering alloys: nickel superalloys (Inconel 718, IN713C, IN939, MarM247), titanium alloys (Ti-6Al-4V Grade 5 and ELI), stainless steels (316L, 17-4PH, 15-5PH, duplex 2205), cobalt alloys (ASTM F75, Stellite grades), aluminium alloys (A356, A357), and carbon and alloy steels. All alloys are melted under appropriate atmospheric controls for the specific alloy chemistry.
Yes. Uni Tritech is India’s first investment casting foundry to receive Airbus approval — making it uniquely qualified as a precision investment casting manufacturer for direct supply into Airbus supply chains globally. The Airbus SQIP approval, combined with Collins Aerospace qualification and four-scope NADCAP accreditation, represents the most comprehensive OEM approval portfolio held by any precision casting company India.
We produce gate, ball, and check valve bodies, pump casings and impellers, subsea manifold components, choke bodies, flanges, and compressor parts in all major API and CRA alloy grades.
Precision investment casting lead times from Uni Tritech are: 6 to 8 weeks for prototypes using 3D-printed wax patterns (no tooling NRE), 8 to 12 weeks for first articles with new wax tooling, and 4 to 7 weeks for repeat production orders where tooling and first article approval exist. Air freight from India to Europe and North America adds 3 to 5 working days to total delivery time.
Yes. Every new precision investment casting programme at Uni Tritech begins with a complimentary Design for Manufacturing review — examining wall thickness, fillet radii, draft angles, parting line placement, core requirements, and tolerance achievability. DFM review consistently reduces tooling cost and first-article failure risk, and is provided at no charge as part of Uni Tritech’s new customer programme qualification service.
