Unrivalled experience in motorsport castings.

At Grainger and Worrall, we understand motorsport, and even more importantly, our motorsport customers. This includes your unique confidentiality requirements and need for high-integrity, precision sand castings- often quickly.

We've developed a specific roll-over casting process to produce the Formula One grade castings demanded by the motorsport industry.







  • We use the flexibility of sand casting prototyping to create high-complexity, high-integrity castings, in a range of alloys to meet the high precision requirements of motorsport.

  • We produce components such as cylinder heads and lightweight racing engines with sand casting.

  • We use our experience in racing, rally engine and transmission programs to meet the demanding, compressed lead times required in motorsport.
  • Our innovative casting expertise ensures you receive the highest possible quality of castings in both aluminium and CGI (compacted graphite iron) to optimise material properties for motorsport.
  • We use technologies such as 3D printing, casting simulation and development of post casting heat treatments to meet the material properties required by motorsport in sand castings.


  • Our in house computer tomography and casting simulation technology combined with our specific Casting process consistently provides the high-integrity castings required by motorsport.

  • This allows us to produce the most reliable, defect-free castings in the world. And we can do it fast.

  • Our materials knowledge allows us to deliver lighter, thinner and more durable precision motorsport castings- vital for downsized engines.

  • We use CT scanning to ensure we meet specifications and tolerancing requirements, delivering high-integrity, lightweight castings.
