What Expromet supplies to the aerospace sector
Expromet Technologies Group produces precision metal components for performance-critical aerospace applications. The group’s four UK manufacturing businesses (Investacast, Haworth Castings, Metaltech Precision and Tiverton Fabrications) cover investment casting, sand casting, gravity die casting, pressure die casting, forging, CNC machining and certified welded fabrication from a single group structure.
The aerospace components Expromet supplies include:
- Aircraft seating components: seat legs, table sliders, pivot blocks, coat hooks and tray table arms for economy and business class interiors. For a detailed look at process selection across the cabin interior, see our article on manufacturing precision metal components for aircraft interiors.
- Avionics: flight recorder housings and enclosures, CNC machined in titanium to tight tolerances.
- Aircraft telemetry systems: bearings, transducer bodies and sub-systems, CNC machined in stainless steel.
- Drone engines: end plates, sand cast in LM13 and molybdenum-bearing aluminium alloys for elevated temperature performance.
- Missile systems: hard back structures, sand cast in LM169 aluminium.
- Parachute delivery systems: safety buckle pins, CNC machined in stainless steel.
- Aircraft ground refuelling systems: hydrant pit lids and bases, CNC machined in aluminium.
- Ordnance: firing mechanisms, sliding head turned in carbon steel.
- Load tie-down systems: quick release couplings, CNC machined in stainless steel.
Tiverton Fabrications: certified welded fabrication joins the Group
In January 2026, Expromet acquired Tiverton Fabrications, extending the Group’s manufacturing capability to include performance-critical welded solutions. Tiverton provides specialist fabrication for advance applications and is developing as the Group’s centre of excellence for fabrication, adding MIG and TIG welding, bespoke vessel manufacture and complex fabricated assemblies to the Expromet offer.
Many cast and machined components require a fabrication stage before they reach the customer, and until now that step required a separate supplier relationship to manage. Bringing Tiverton into the Group means Expromet can now take ownership of that handover, reducing the number of interfaces a customer needs to manage, shortening the overall supply chain and maintaining quality oversight across the full production sequence.
Tiverton holds ISO 3834-2 welding quality certification and brings with it SGS-certified quality management and an experienced team of qualified MIG and TIG welders working to the latest ISO and ASME standards.
The manufacturing case for a multi-process group supplier
Most precision component manufacturers specialise in one process. That constraint shapes the advice they give: a casting house will recommend casting; a machine shop will recommend machining from solid. The result is that process selection is often driven by supplier capability rather than component requirements.
Expromet works differently. Because the Group has expert casting, forging, machining and fabrication capability across its operating companies, the starting point is always the component itself (its geometry, load case, material requirements, volume and finishing specification) rather than the process available. This is the argument for single-source manufacturing for performance-critical components: fewer handovers, clearer accountability and better-informed process selection from the outset.
For aerospace customers, this matters for several reasons.
- Process selection directly affects cost, weight and structural performance. A structural seat component currently machined from solid 17-4PH stainless steel, for example, may be a strong candidate for investment casting: the near-net-shape result reduces material waste and machining time, while maintaining the mechanical properties required for certification. Conversely, a component carrying significant cyclic fatigue loads may benefit from closed die forging over casting, because forging preserves continuous grain flow through the part geometry.
- Supply chain consolidation reduces programme risk. Aerospace OEMs and Tier 1s managing separate supplier relationships for cast, forged, machined and fabricated parts carry more coordination overhead, more quality interfaces and more schedule risk than those who can access multiple processes through a single, technically accountable partner. Expromet provides end-to-end supply chain management, including outsourced supply and trusted overseas manufacturing partners for specific processes and volumes, with UK-based programme management and quality oversight throughout. Our recent article on why OEMs and Tier 1s are moving to integrated manufacturing partners explores this in more detail.
- Design for Manufacture (DfM) support improves outcomes before production begins. Expromet’s engineering team can review component designs early in the programme, identifying opportunities to improve manufacturability, reduce cost or de-risk certification. This is particularly valuable in aerospace, where late-stage design changes carry significant cost and schedule consequences.
Quality and certification
Expromet companies’ aerospace and defence quality credentials include:
- AS9100 certification at Metaltech Precision (the internationally recognised quality management standard for aviation, space and defence manufacturing)
- ISO 9001 across all Group companies
- JOSCAR accreditation held by Investacast, Haworth Castings and Metaltech Precision (the aerospace and defence supplier registration scheme used by BAE Systems, Airbus, Leonardo, Rolls-Royce and other major primes to pre-qualify their supply chains)
- ISO 3834-2 welding quality certification at Tiverton Fabrications
- UKAS-approved NDT testing and inspection (covering CMM dimensional inspection, ultrasonic testing, X-ray and magnetic particle inspection)
- Full material traceability throughout the manufacturing process
- ISO 14001 environmental management certification
- ISO 45001 occupational health and safety certification.
JOSCAR accreditation is particularly relevant for aerospace procurement teams. It means It means Investacast, Haworth Castings and Metaltech Precision have already been assessed against the criteria used by major aerospace and defence prime contractors, reducing the supplier qualification burden at programme entry.
Expromet Group’s aerospace track record
Expromet’s Group companies have long-standing supply relationships across the aerospace sector. Investacast is one of the UK’s most established suppliers of investment castings, with a manufacturing base in Devon and a global sourcing network across Asia. Metaltech Precision operates a 50,000 sq ft facility in Somerset with over 50 machining centres, including 5-axis capability, large-format travelling column milling, sliding head turning and an expanding lights-out automated manufacturing capability. Haworth Castings, based in Hampshire, specialises in sand and gravity die castings for performance-critical applications.
Expromet’s Group companies have supplied aerospace customers across both development and production phases, building long-term relationships with OEMs and Tier 1 contractors in aircraft interiors, defence and the wider aerospace sector.
The Group has an established track record of converting components currently manufactured by machining from solid into castings or forgings, maintaining full structural and certification compliance while reducing cost and lead time for customers. For aerospace manufacturers under cost pressure, this engineering-led conversion capability is often a significant source of programme savings.
