Gravity die casting solutions for the defence industry
As gravity die casting specialists with over 60 years experience, Roston Castings are highly respected experts in the manufacture of aluminium components for defence applications. We have supplied high-quality aluminium castings for a wide range of technical applications and are trusted by leading manufacturers across automotive, aerospace, agriculture and engineering.
Die Casting for Defence
The die casting manufacturing process is renowned for producing components with high dimensional accuracy, strength and an excellent surface finish. These can include fighting vehicle components, hand controllers, comms/navigation enclosures and electronic housings.
Die casting allows you to benefit from the unique properties of various metals – typically defence grade aluminium – which is vital for the production of lightweight components.
Advantages of die casting
We offer high performing gravity die casting, a method with a number of benefits over high pressure casting. A critical factor in the gravity die casting process is the cooling phase, which allows the metal to cool slower and therefore more evenly, producing more durable castings with a higher density and fewer porosity issues.
This helps contribute to products with stronger and more durable properties capable of higher levels of performance. A controlled filling process also makes for tighter tolerances and more consistent dimensions – especially important in the defence industry applications where quality is crucial.
For high-volume manufacturing, gravity die casting allows you to create highly complex, thin-walled shapes and consistently produce high-quality parts quickly while maintaining narrow tolerances.
Gravity die casting also offers cost benefits over large production runs as the moulds’ reusable nature leads to lower per-part costs and reduced waste.
After casting, we complete the finishing process to ensure the best possible result. Our machining capabilities allow us to finish your defence aluminium castings to exacting standards with post processes as appropriate.
