At Sarginsons Industries Ltd, we combine advanced gravity die casting with world-leading simulation and foundry technology to produce low-porosity aluminium components for the most demanding automotive and industrial applications. From safety-critical structures to complex housings, our focus is always the same: lighter, stronger, more sustainable castings.
Gravity die casting is particularly suitable where strength, wall thickness and robustness matter more than ultra-high production rates. Typical applications include:
Sarginsons is an aluminium foundry focused on castings where strength, integrity and consistency are critical.
By combining recycled and secondary alloys with tightly controlled processes, we help OEMs and Tier 1s lightweight components, reduce CO₂ and strengthen their supply chains.
Every programme is different, but the way we work is consistent and technology-led:
Concept & Simulation – Review CAD and load cases, then use Digital Twin Simulations to de-risk the design.
Tooling & Die Design – Engineer the die, gating and cooling for robust filling and solidification.
Die Manufacture & Prove-Out – Manufacture and optimise tools using real casting and simulation feedback.
Casting & Heat Treatment – Cast under controlled conditions, then heat treat to achieve specified properties.
Machining & Inspection – CNC machine, finish and inspect castings to drawing, with continuous feedback into future runs.
From first concept to fully inspected parts, our gravity die casting process combines proven foundry practice with advanced simulation for repeatable, high-integrity components.
Gravity die casting, simply called gravity casting, uses a permanent steel or cast-iron die, using gravity rather than high pressure to cast. For aluminium, this process offers a powerful balance of mechanical performance, dimensional control and tooling cost, making it ideal for many structural and safety-critical parts.
Gravity die casting at Sarginsons is tightly integrated with our advanced casting technologies. This means our gravity castings benefit from the same Digital Twin Simulations, Topological Light weighting and Smart Cooling that underpin our work in low pressure and sand casting
Sarginsons brings process range, technology and control together in one aluminium foundry:
Whether you’re developing a new aluminium platform, converting fabrications to castings or looking for a more robust process route, we can help you decide if gravity die casting is the right fit.
