Our areas of activity
Our expertise in aluminium foundry
We have been specialized in thealuminium foundryfor over 30 years. Our expertise is based on two main techniques:sand castingand theshell casting. These processes allow us to meet a wide variety of needs, in small or medium series.
Each part is designed with precision, according to your plans or in co-design with our design office. We master tight tolerances, specific finishes, heat treatments, and non-destructive testing. And we know how to adapt our processes to your business constraints, without compromising on quality.
We use aluminium alloys tailored to each application. Mechanical properties, corrosion resistance, and thermal conductivity are studied based on the application. Our technicians rigorously follow each project from the model to the finished product.

Parts for industry, designed to last
Our parts find their place in many industrial sectors. We work notably for:
- – the sectorautomotive: structural parts, housings, supports
- – rail transport: housings, chassis, technical components
- – naval and offshore: mechanical elements exposed to corrosive environments
- – construction and infrastructure: fasteners, custom elements
- – energy and industrial equipment: dissipators, connectors, protective casings
Each project is unique. That is why we adapt our tools, our deadlines, and our volumes to your expectations. Theproduction of custom parts, is our core business.
A foundry committed to quality and the environment
We are committed to a demanding quality approach. Each part is inspected according to strict protocols, with appropriate equipment: spectrometer, dimensional controls, mechanical tests, etc. We can respond to complex specifications, particularly for regulated sectors.
We are also committed to environmental issues. We use recycled aluminium whenever possible, we optimize our processes to limit waste, and we comply with current standards. Producing locally also means reducing the carbon footprint associated with transportation.
