Aluminium Investment Casting
Capabilities
Dean Group is a UK-based foundry specialising in high-integrity aluminium investment casting.
Our ELITE process enhances this even further, offering gas-tight castings with refined microstructure, which is ideal for pressure systems, housings, and structural parts.
Benefits of Aluminium Investment Casting
- Design freedom – create complex or internal geometries that die casting can’t achieve.
- Thin wall sections – reduce weight without compromising strength.
- Excellent surface finish – reduces post-processing, ideal for visible or sealed components.
- Material performance – choose from a range of aluminium alloys suited to your application.
- Consistent repeatability – from one-off to production volumes.
- UK-based – faster lead times, lower risk, and easier communication.
If your project demands lightweight, precision aluminium parts (and you can’t afford leak paths or structural failure), investment casting is often the right choice.
Our Capabilities
We produce aluminium castings from a few grams up to 15kg, and up to 500mm³ in volume. Our process supports tight tolerances, full traceability, and inspection options including x-ray and dye penetrant testing.
We also offer in-house tooling development and 3D-printed patterns for faster turnaround and prototyping.
Typical batch sizes range from low volumes up to several thousand parts per year, depending on complexity.
Who We Work With
Our aluminium investment castings are used in:
- Aerospace – gas-tight parts, housings, brackets
- Defence – high-performance components with full documentation
- Medical – clean, precise, traceable components
- Electronics & sensors – thin-walled enclosures, EMI shielding
- Motorsport & performance engineering – lightweight structural components

FAQs
Investment casting uses wax patterns and ceramic moulds, ideal for complex shapes and lower volumes. Die casting uses metal moulds, better for high-volume production but less flexible in design.
Yes. It’s commonly used for aerospace components that need to be lightweight, gas-tight, and structurally sound. Dean Group supplies aluminium castings to aerospace and defence clients with full traceability and inspection options.
We cast parts from a few grams to 15kg and up to 500 mm³. This covers a wide range of aerospace, medical, and industrial applications.
Our process achieves excellent dimensional accuracy and repeatability. We also offer X-ray and dye penetrant testing, where required, to verify casting integrity.
Yes. Send us your CAD file or technical drawing, and our engineers will review it. We can also advise on design for manufacturability.
We supply into aerospace, defence, medical devices, electronics, motorsport, and general engineering anywhere that needs lightweight, precise, high-integrity components.
