In today’s rapidly changing defence landscape, readiness, resilience, and technological superiority are critical to maintaining operational advantage. As a leading British manufacturer, Finecast plays a key role in supporting the critical supply chains that underpin the UK’s armed forces and aerospace platforms.
We provide casting solutions engineered for the most demanding mission-critical applications in defence and aerospace. From armoured vehicles and naval components to high-performance aerospace applications, our castings deliver consistent structural integrity and performance under high mechanical loads, thermal extremes, corrosive environments, and sustained operational demands.
Supporting the UK’s Defence Strategy
Strategic defence reviews and sustained investment in modernising equipment have placed advanced manufacturing at the centre of the UK’s future capability. Finecast proudly supports this strategy, supplying castings for air, land and sea platforms.
With AS/EN9100-certified manufacturing and full in-house control at every stage, we ensure compliance, full traceability, and repeatability to the highest international defence and aerospace standards. Our specialist team brings extensive knowledge and proven experience in producing high-integrity castings — manufactured and certified daily to AMS 2175 Grade B. This rigorous quality framework has made Finecast a trusted partner to Tier 1 defence and aerospace organisations worldwide, delivering lightweight, performance-critical components that perform reliably under extreme conditions.
Defence & Aerospace Services That Deliver
Our full-service model integrates every stage of the casting journey, giving our defence clients complete confidence in quality, lead times, and technical performance.
Our capabilities and unique advantages include:
- 3D CAD Design & Engineering — Up-front engineered, production-ready designs optimised for performance, weight reduction, and manufacturability, enabling a proven low-risk route to production.
- Virtual Casting Simulation — Proves performance before production by eliminating defects, validating design, and optimising stress and distortion for right-first-time manufacturing.
- Rapid Additive Manufacturing — Tool-less 3D Sand Printing — Direct-from-CAD 3D printing of complex shapes with no tooling required, enabling high-integrity castings across a wide range of materials, accelerating prototyping through to production.
- Prototype & Production Foundry — Flexible foundry operations for one-off prototypes, development parts, aftermarket components, and volume supply — achieving mechanical properties beyond traditional sand casting methods.
- Laboratory-Controlled Metallurgy — In-house metallurgical testing validates alloy chemistries, mechanical properties, and microstructures to international defence and aerospace standards, supporting bespoke alloy development and safety-critical integrity.
- Heat Treatment —In-house thermal processing to control and enhance mechanical properties, ensuring consistency, repeatability, and compliance with defence and aerospace standards.
- Non-Destructive Testing — In-house GE digital radiography, computed tomography, DPI, MPI, and UT for full internal and surface integrity validation to aerospace and defence standards.
- 5-Axis CNC Machining & CMM Inspection — Extensive CNC capacity with dimensional verification using CMM, GOM/Creaform optical scanning, and CT — supplied with GD&T-compliant ISIR/FAIR reports, CPK indices, and SPC analysis.
- Mechanical Sub-Assembly & Fitting — Complete in-house sub assembly and fitting service, delivering installation-ready, safety-critical components—reducing programme costs and supply chain complexity.
Finecast components are engineered to meet demanding specifications for strength, weight reduction, corrosion resistance, and thermal stability — qualities essential to both defence and aerospace programmes.
Certification & Accreditation
To meet the highest defence and aerospace requirements, we operate under a robust framework of industry-recognised certifications:
- AS/EN9100 Certified – Aerospace Quality Management
- JOSCAR Registered – Trusted by defence primes and procurement teams
- Cyber Essentials Certified – Ensuring digital resilience and data security
All manufacturing is carried out in-house, giving us full control over quality, consistency, and lead time. Every component we produce is delivered with complete traceability and certification — from raw alloy to finished, fully machined and validated cast product.
Proven Performance. Future Focused.
We don’t just manufacture castings — we engineer performance, reduce risk, and deliver solutions that give our clients a tactical edge. Whether supporting existing platforms or next-generation systems, Finecast stands ready to meet the UK’s defence and aerospace manufacturing challenges head-on.
