Aluminium Air Set Sand Castings
Our air set sand casting process produces complex, large-scale aluminium components with exceptional dimensional accuracy. Using resin-bound sand moulds, we achieve intricate designs up to 200kg without size limitations. The method combines 75% reclaimed sand for sustainability while maintaining structural integrity for industries like defence and utilities.
Precision CNC Machining Services
Integrated within our foundry operations, our CNC machining services handle materials from aluminium to stainless steel. With 6 lathes and 5 machining centres, we deliver tight tolerances up to 500mm diameter. ISO 9001-certified processes ensure quality for sectors including marine and general engineering, from prototypes to mass production.
Gravity Die Casting
Specialising in gravity die casting, we produce high-volume aluminium components with superior surface finish and dimensional precision. Using reusable cast iron dies, we create parts with LM6, LM9, LM25, and LM27 alloys. This method reduces secondary machining needs while maintaining consistency for aerospace and automotive applications.
Pattern Making
Our pattern making utilises CAD/CAM and 3D modelling to create precise prototypes for casting. Using wood, resin, and model board, we design feeding systems that minimise defects. This critical phase ensures accurate mould creation, supporting rapid prototyping and complex geometries for industrial machinery and energy sectors.
Material Specifications
We offer BS1490-compliant aluminium alloys including LM25, LM27, LM6, and LM9, each tailored to specific mechanical and corrosion-resistant properties. Our metallurgists advise on optimal material choices for applications ranging from marine components to high-strength aerospace parts, ensuring compliance with industry standards.
Questions
What industries do you supply?
We serve marine, rail, aerospace, energy, utilities, defence, and general engineering sectors with precision castings and machining.
Are you ISO 9001 certified?
Yes, we operate under ISO 9001:2015 quality management with BS1490 compliance for all aluminium alloys.
Can you reverse engineer components?
Yes, we frequently work from sample parts to produce replacement or refined designs using reverse engineering.
What sustainability practices do you follow?
We use 100% recycled aluminium and reclaim 75% of sand during production to reduce environmental impact.
What is the difference between sand and gravity die casting?
Sand casting suits low-to-medium volume complex designs, while gravity die casting offers tighter tolerances for high-volume production.
Do you handle small batch orders?
Yes, our air set sand casting process supports rapid prototyping and small production runs up to 200kg.
