Our specialist prototype aluminium foundry meets product development demands with a novel approach- for both pre-production and production intent prototypes. Whether you need high precision sand castings for engine, vehicle, aerospace or industrial markets, we add value and integrity at every stage of the process.


Highly complex air set sand castings

Our core capability focuses on highly complex air set sand castings. We’ve developed an extensive library of alternative aluminium alloys for the diverse applications demanded by our varied customers.
Our Aluminium Cast products demonstrate superior quality and performance through application of best practise and technology. Multiple sand medias Silica, Chromite, Alumina, Zircon are employed along with appropriate coatings and chill placement within our high precision engineered moulds.


Innovative aluminium castings for the next technological generation

The key driver for our prototype aluminium casting has been technological and legislative advances in vehicle and engine design.

Low Carbon vehicle technologies need lighter, stronger and more powerful engines – and the same demands are true of the castings. At Grainger & Worrall, we’ve led an innovative and exceptional process to design, make and verify exceptional prototype castings, allowing us to meet the demands of the next generation.
