Industrial expertise since 1973

Our story began in 1973 with the founding of Dupuis Mécanique and the development of our precision engineering expertise. In 1981, we began focusing part of our activities on the aeronautics industry, a sector with particularly demanding quality and manufacturing requirements. Today, our new identity, Belrise SDM, marks the continuation of this industrial journey. We work from the drawings and specifications provided by our clients to manufacture components tailored to their needs.

Our organisation brings together technical preparation, manufacturing and production monitoring. This experience enables us to support our clients, from one-off parts to series production.

Contact Belrise SDM about your precision machining projects

We are here to discuss your precision engineering requirements
and support you in bringing your industrial projects to life.

Critical components for aerospace and defence

The aerospace industry is our main area of activity, with a strong focus on the manufacture of aeronautical components. In particular, we produce precision mechanical parts and structural elements that meet our clients’ technical specifications. In the field of air and land defence, we draw on our machining capabilities to manufacture components tailored to the requirements of each programme.

We pay particular attention to the confidentiality of projects and the technical data shared with us. Our experience in machining critical components guides how we prepare operations and select inspection equipment. We adapt our processes to the characteristics of each component.

Our expertise at the service of industry

We apply our precision engineering expertise across industry to meet a wide range of manufacturing and maintenance requirements. In telecommunications, we machine mechanical components for equipment and technical installations. For the food processing industry, we produce custom-made parts to support the improvement and maintenance of production equipment.

In the energy sector, we manufacture components that meet the specifications of industrial installations. Each sector presents particular constraints that guide our manufacturing decisions. We plan our operations around the geometry of each part, the materials involved and the required quantities.

Solutions for your technical applications

For motorsport, we manufacture custom-made parts for competition vehicles, according to the specific needs of each programme. For the medical sector, we support industrial companies in manufacturing precision mechanical components to their technical specifications. Our experience in demanding sectors informs the care we take in preparing operations and performing dimensional inspection.

We adapt our methods to the properties of the materials and the required geometries. Depending on your needs, production may involve a single part or a series of identical components. This versatility enables us to meet a wide range of requests while maintaining a rigorous approach.

Production capabilities tailored to your requirements

We use CNC turning and CNC milling equipment to manufacture precision mechanical parts. Our three-, four- and five-axis milling machines enable us to machine complex geometries, depending on the characteristics of each component. Electrical discharge machining (EDM) complements these processes for certain cutting and drilling operations. We plan our work from your drawings to select equipment suited to the dimensions and materials involved.

Our computerised production management system facilitates the monitoring of operations and the traceability of parts. Our measuring equipment also helps verify the dimensional characteristics set out in your specifications.

Note: The choice of machining processes depends in particular on the geometry of the part, its material and the dimensional requirements specified on the drawing.

Inspection of manufactured parts

Quality at the heart of our commitments

Quality is integral to every stage of our work, from preparing operations to the inspection of manufactured parts. Our ISO 9001 and EN 9100 certifications reflect our commitment to controlling our production processes. We define inspection procedures according to component characteristics and the requirements communicated by our clients. Our computerised monitoring system helps organise production and ensure traceability.

We also pay particular attention to the technical discussions needed to understand each order fully. This approach supports the manufacture of parts that meet the agreed specifications.

The strength of an international industrial group

As part of the Belrise Industries group, we bring our long-standing expertise into an international industrial environment. We continue to manufacture precision mechanical parts under our new identity, Belrise SDM. The group brings together a range of industrial capabilities, including those of Belrise Aerospace & Defence, based in India.

There are also plans to explore synergies with Chester Hall, in the United Kingdom, for projects requiring the machining of large parts. Our own operations remain focused on manufacturing small parts. This new direction opens up opportunities for collaboration between the group's different entities.
