Grainger & Worrall specializes in producing lightweight, high-integrity sand castings made of aluminium that meet the automotive industry's demands for Internal Combustion Engine (ICE) components. Our sand casting expertise, combined with our in-depth knowledge of materials, allows us to create customized aluminium alloys that are strong, precise, and lightweight, thus enabling the development of modern ICE components and applications. Our accurate and rapid production process ensures consistent quality every time.

Here at Grainger & Worrall, we know motorsport. Perhaps even more importantly, we know our motorsport customers. This includes your need for confidentiality, high-integrity, precision castings and compressed lead times.

We've developed a specific casting process to produce the Formula One grade castings demanded by the motorsport industry. This allows us to produce the most reliable, defect-free castings in the world.

We create the high-precision, powerful and lightweight castings required in by the aviation industry. This includes properties of fatigue resistance, high surface finish and dimensional stability.

Aluminium sand castings and bespoke alloys allow us to create the lightweight, complex and strong metal shapes required for powerful aviation performance while reducing aerodynamic drag. This includes engine components for single and twin engined aircraft, as well as helicopters. 

Defence procurement requires R&D innovation, production flexibility and expert engineering. Our sand casting experience allows us to work with your engineering or technical directors to meet your defence programme requirements with a precision-driven, right-first-time approach.

We understand the dynamics of defence, and our capacity allows us to respond to changes in timescales. We specialise in innovating from concept through to production. And we do it fast. 

We create the complex metal shapes required in marine-grade castings. Our  materials knowledge allows us to create castings in marine-grade aluminium alloys, optimised for performance, function and properties such as machinability, erosion and corrosion resistance.

We combine our sand casting expertise with cutting edge technology to meet your high performance requirements. And we do it fast, without jeopardising quality control or casting accuracy.

Our materials knowledge and innovative prototyping approach allow us to produce sand castings that meet the engineering challenges faced by the energy sector against a global background of achieving a carbon neutral future.

Aluminium castings allow us to create the lightweight, durable, wear resistant and dimensionally stable metal shapes required to both help reduce emissions and meet the exacting energy sector performance demands.

We approach architectural sand casting challenges with creativity and flexibility, producing durable castings that are often large, niche and highly technical. Our processes give repeatability and manufacturing confidence in low and medium volumes needed for architectural castings

Aluminium castings allow us to create the lightweight, complex yet strong metal shapes required in architectural projects such as prestige facades, roof panels and tiles.
