Flexible, right-first-time castings.

At GW we know 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 can do it quicky.

Our technical knowledge of aluminium castings allows us to produce lightweight defence components optimised for better fuel management, manoeuvrability, stability and durability across defence applications including parts for:

  • Maritime
  • Drones
  • Helicopters
  • Artillery
  • Military vehicles

 

 

 

Dynamic, accurate defence castings that are lighter, stronger and smaller


Our flexible, UK based supply chain gives us the scope and flexibility required to respond to changing defence programme timescales, as well as upgrade capability and longevity.

  • Right-first-time for life saving lead times. We’ll respond effectively to the ‘hurry up and wait’ dynamic of defence with flexibility, while our right first time approach reduces lead time.

  • Material expertise. We produce high integrity, safety-critical precision castings which are optimised for lightweighting and performance.

  • Prototyping design flexibility.  Prototyping with sand casting technology gives us flexibility to respond to design modifications in defence projects without the cost implications of expensive tooling, ensuring we can effectively move from prototyping into low volume production.

  • Individual services. Our innovative approach to design support, R&D and early prototyping and development drives procurement efficiencies, as well as maximise the required material properties and function of components.
