Precision Defence & Military Casting

Flexible, Right-first-time Castings.

At Grainger & Worrall, we know defence procurement requires R&D innovation, production flexibility and expert engineering. Our experience in precision defence castings allows us to work with your engineering or technical teams to meet your defence programme requirements with a precision-driven, right-first-time approach.

We'll work to determine which materials will work best for your defence product. This allows us to create castings balanced for weight, strength and tensile range.

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 quickly.

The Defence Dynamics

We understand that each defence application has its own set of unique requirements and challenges. While that may be the case, our experience and expertise can help cross-fertilise innovation between sectors. We help you master the metal to achieve the functionality for your operational requirements.

Our technical knowledge of aluminium sand castings for defence allows us to produce lightweight military components optimised for fuel management, manoeuvrability, stability and durability. Defence applications include sand castings for military vehicles and parts for:

Maritime
Drones
Helicopters
Combat Vehicles
Artillery

Dynamic, High-Integrity Defence Castings That Are Lighter, Stronger And Smaller

Our dynamic engineering and casting processes give us the 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 respond effectively to the dynamic nature of defence with flexibility, while our right-first-time approach reduces lead times and keeps costs low.
Material expertise. We produce high-integrity, safety-critical precision castings which are optimised for lightweighting and performance.
Volume Flexibility. We specialise in low and niche volume production. We can support a programme from 1-off prototypes, right through to 20,000 p/a. But we’re not just prototype or automated production, we also specialise in the niche/low volumes typically seen in defence, i.e 20 - 2000p/a.

Creating Lightweight, Complex Metal Shapes For Defence.

Prototyping design flexibility. Prototyping with sand casting technology gives us the 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 maximising the required material properties and function of components.

Innovation Meets Quality

Grainger and Worrall are passionate about innovation and quality.

It impacts everything we do.

Whether it's innovating with rapid prototyping for defence applications, or driving lightweighting for lighter, more durable F1 engines, we make sure every part is fit-for-purpose and meets the quality specifications our customers expect.
