Flying into the future with precision sand castings. 

At G&W, we use our materials knowledge, prototyping innovation and expertise in sand casting for automotive engines to create the high-precision, powerful and lightweight castings required in aviation engineering.

Aluminium sand castings and bespoke alloys allow us to create the lightweight and complex, yet 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. 


precision sand castings that solve aviation challenges


  • We use the flexibility of sand casting to create complex geometries in a single shape and in a range of alloys for a variety of aviation applications.
  • Our investment in cutting edge casting technology such as 3D additive sand printing allows us to create castings quickly, meeting your often tight or changeable aerospace project timetables.
  • We develop unique alloy chemistries, which support lightweighting efforts to reduce fuel consumption and aerodynamic drag, as well as other key material properties demanded for aerospace.


  • Magma simulation software allows us to prototype properties prior to production, reducing unnecessary weight and overengineering.

  • At G&W, we use our automotive ICE engine expertise to cast precise, high-integrity, highly technical aviation engine components.

  • This includes utilising bespoke alloys (aluminium and CGI) and lightweighting through design and process optimisation for increased fuel efficiencies across aviation components.

  • Our inspection capabilities include CT scanning and GOM measurement to ensure we meet the tight specifications and accreditation demanded by the aviation sector.
