lightweight, precise castings for modern ICE automotive.

At Grainger and Worrall, we create the high-integrity, lightweight aluminium sand castings demanded by the automotive industry for ICE engine components. 

We use our sand casting expertise, as well as materials knowledge to create bespoke aluminium alloys that are strong, light and precise, driving modern ICE components and applications. And we do it accurately and fast. Every time.




Precision ICE automotive sand castings, from first concept through to proven concept.


expertise in sand casting for ICE automotive applications you can rely on.

  • We develop specific and bespoke alloys that retain their mechanical properties in temperature-critical applications,  crucial to match ICE engine temperature increases

  • We produce high-integrity and high-performance sand castings for ICE that allow us to supply series and prototype engine components which model production parts with MLP production properties.

  • We work with our automotive customers to solve complex problems with innovation and prototyping expertise in sand casting ICE components

  • We use inspection techniques such as CT scanning and GOM measurement to ensure we meet tight tolerance specifications and requirements, delivering high integrity castings for ICE every single time.

  • We’re able to reduce time-to-market for compressed lead times with innovative techniques and technologies to speed up manufacture, such as 3D digital sand printing. 

  • Bespoke alloys and ability to create complex, net shapes with sand casting allow us to meet lightweighting and part count reduction demands in ICE engine components

  • Our sand casting expertise adds value at every stage of development, including in prototyping, initial concepts and proof of concept.
