Four Companies, One Group Vision

We employ 280 people across three manufacturing centres of excellence, specialising in sand castings, centrifugal castings, finish machining, assembly and supply chain led solutions. Ranging from small engineering companies to global blue-chip organisations, our customers have the combined resources of all four Companies available to them, benefiting from a pool of technical knowledge and manufacturing expertise.
Spunalloys is the UK’s largest, most diverse non-ferrous and ferrous centrifugal castings foundry. Rings, tubes and special shapes are offered either proof or finish machined, fully tested, certified and assembled as required. Our world-leading range of heat, wear and corrosion resistant materials includes copper, nickel based alloys, special irons, steel and other exotic materials. We engineer safety critical products for naval and marine propulsion shaft liners, column pipe/riser mains for offshore vertical pumps, environmentally critical wellhead products for the oil & gas industries, and special alloys for the aerospace turbine industry.

Europe’s largest and most experienced non-ferrous foundry is the result of a strategically consolidated consortium of sand casting foundries. Market leaders in the design and supply of high-integrity heat, wear and corrosion resistant alloys, our castings range from 1kg to 10 tonnes, using unique production methods such as HPLT/Durville inverted pouring. Often for major naval and defence contracts, our experienced technicians are well-equipped to manage the most demanding quality requirements of safety critical components.

Our extensive precision machine shop has invested heavily in suites of CNC machining centres and lathes. We support all foundry activities, with a vertically integrated supply chain solution for fully machined and assembled castings in the heat, wear and corrosion resistant alloys that we cast. Collaborating with the customer and foundry to deliver demanding NDT, certification and full assembly, we also manufacture FranBerLube™ bearings – a specially developed range of self-lubricating bearings and wear plates suited to harsh environments.
