Mechanical design
Mechanical design office: from idea to machine
Custom presses, special machines, assembly stations, tooling and test benches: our designers and engineers model in 3D, size the components, have them manufactured and commission your equipment in our workshops.

A design office that goes all the way to the running machine
A mechanical design office turns a functional need into a technical solution that is reliable, manufacturable and compliant. Ours does not stop at the drawings: it manages the manufacturing of the parts, the assembly and the commissioning in our workshops, then the installation at your site.
You have a single point of contact, from the specifications to the production start-up, with teams near Nantes and in Normandy. Mechanics, automation, robotics and vision are designed together, which avoids nasty surprises at the interfaces.
What our design office designs
Custom presses
Pneumatic, hydropneumatic and electric presses for press-fitting, crimping, riveting or marking.
Learn moreSpecial machines
Automatic machines and semi-automatic assembly stations designed for your product.
Learn moreTooling
Custom jigs, fixtures, grippers and inspection tooling.
Learn moreTest benches
Functional, leak, force or endurance test benches.
Machine guarding
Guards, protections and secured access for your machines and cells.
Learn moreMechanical retrofit
Modernization and upgrading of existing machines.
Learn more3D design, calculation and deliverables
We design with SolidWorks and Autodesk Inventor, two industry-standard 3D CAD environments, and we verify stressed parts through strength-of-materials calculations.
- Full 3D modeling, drawings, bills of materials and manufacturing files
- Strength-of-materials calculation of structures, sections and bolted and welded joints
- Motion simulation and interference checking
- Delivery of native files and of the STEP, IGES, DXF and PDF exchange formats
- You remain the owner of your design data

From specifications to delivery
- 01
Needs analysis
Review of the specifications, visit to the workstation, throughput, ergonomics and safety constraints.
- 02
Preliminary design
One to three technical concepts, compared on cost, lead time and maintainability.
- 03
Detailed design
3D modeling, strength-of-materials calculation, drawings and bills of materials, validated with you at each milestone.

Manufacturing and commissioning
Parts machined by our partners, assembly and testing in our workshops, installation on site.
Frequently asked questions
What is a mechanical design office?
It is a team of engineers and design draftsmen that designs industrial equipment: 3D modeling, strength-of-materials calculation, drawings and manufacturing files. Ours also handles the manufacturing, assembly and commissioning.
How do you choose a design office?
Look at its references in your sector, its ability to carry the project all the way to a working machine, and its command of CE compliance. A design office that manufactures and commissions in-house commits to the result, not just to the drawings.
Which CAD software do you use?
SolidWorks and Autodesk Inventor. We deliver the native files as well as the STEP, IGES, DXF and PDF exchange formats.
Can you take over a machine you did not design?
Yes. We survey the existing equipment, model it if necessary, then modify or modernize it as part of a retrofit.
What budget should I plan for?
Each project is quoted individually according to the complexity of the tooling, machine or automated line. We always look for the most economical solution that meets your objectives.
Where are you located?
In Grandchamp-des-Fontaines, north of Nantes, and in Normandy near Rouen. We work throughout western France and across the whole country.
Equipment to design?
Send us your specifications, even incomplete: we will help you refine them and propose a preliminary design.
