Aluminium foundry in Nantes: our expertise at the service of your technical parts
At Rhonalu, we have been manufacturing aluminium parts for over 30 years. In Nantes and throughout France, we support manufacturers in the design and production of custom parts, in small and medium series. Our foundry specializes in technical, functional, and robust solutions to meet the requirements of your projects.
We have grown with our clients, relying on solid expertise, an experienced team, and an agile organization.
With us, there is no impersonal mass production. Each project is handled with rigor, method, and attention. We combine the flexibility of a responsive structure with the industrial requirements of a reliable and structured player.
Our strength is our ability to adapt. To your technical constraints. To your deadlines. To your volumes. And above all, to your ambitions.
Our services in gravity and sand aluminium foundry
We work using two main processes: molding inshell severityand thesand castingThese techniques allow us to produce precise, strong aluminium parts with complex geometries.
We intervene throughout the entire production cycle: study, tooling design, foundry,machiningthermal treatments, finishes, quality controls.
We use a wide range of aluminium alloys, depending on the mechanical, thermal, or corrosion constraints of your parts. Whether forprototypes, of theunitaryor somerepetitive serieswe assist you in choosing the best process and the right alloy.
Our areas of activity
Parts for all industrial sectors
We manufacture parts for very diverse fields. This is what makes our wealth and our adaptability.
Aerospace,automotive, rail, energy, medical, military, or even special machines: we understand the specificities of each sector. We know how to anticipate expectations, master tolerances, and comply with standards.
Our parts are designed to last. And in often demanding conditions. Mechanical resistance, lightness, dimensional precision, surface quality: every detail matters.
Our production method: rigor, control, and dialogue
Each project starts with an exchange. We listen to your needs, your constraints, your objectives. Then we move on to the technical study, the design of the tools, and the validation of the process.
Then comes the actual manufacturing: molding, deburring, treatment, machining. We also ensure thequality controlsintermediaries and finals, at each stage.
Finally, the delivery. On time. As planned. And ready to be used.
Throughout the project, we remain available. To adjust, react, refine. And ensure a smooth and surprise-free production.
Quality, traceability, innovation: our ongoing commitment
We are ISO 9001 certified. All our processes are documented, tracked, and audited. We use destructive and non-destructive control tools, depending on the requirements of your parts.
But beyond the standards, we cultivate a culture of continuous improvement. Each piece is an opportunity to do better. Fairer. More sustainable.
We regularly invest in our equipment, our digital tools, and the training of our teams. Because being a trusted aluminium foundry is built every day.
