A special machine for your specific sector of activity
Does your activity not correspond to any of the sectors mentioned? SMI also designs fully customized special machines, whatever your field. Our design office analyzes your environment, constraints, and objectives in order to create a tailor-made solution that meets the requirements of your company, in France or internationally.
Why have a special machine custom-built for your business with SMI?
Optimize an industrial process designed specifically for your needs
A special machine is not standard equipment: it is designed to fit your parts, your products, your operations, and your industrial constraints. At SMI, each study incorporates your assembly or control precision requirements to create a perfectly tailored solution.
This customization eliminates unnecessary tasks, streamlines manufacturing, reduces handling, and results in more reliable and consistent production, regardless of your industry (food, plastics, wood, mechanical, medical, metal, etc.).
Reduce costs associated with manual operations and multiple equipment
With a special machine, you can replace several scattered operations with a single piece of equipment designed to consolidate, simplify, or automate certain key phases: assembly, quality control, handling, etc.
- By limiting intermediate stages, you reduce:
- setup times,
- material losses,
- maintenance requirements,
- and investments in multiple generic machines.
SMI's tailor-made approach thus creates a more cost-effective, sustainable solution that is better suited to your production volumes.
Enhance the safety and reliability of your industrial operations
The special machines designed by SMI incorporate from the outset the constraints associated with your product, your production rate, and your industrial environment. The risks associated with handling heavy parts, cutting, mechanical welding, heating, or repetitive movements are greatly reduced thanks to custom-designed devices.
Each piece of equipment is designed to protect your employees, simplify their operations, and guarantee consistent quality, even for complex production processes requiring measurement, precision, and technical rigor.
Entrust the design and manufacture of your special-purpose machine to our design office
For over 30 years, SMI has been putting its expertise in engineering and mechanical design at the service of industrial companies wishing to develop a custom machine perfectly suited to their processes.
Located in the heart of the Vosges mountains in northeastern France, our design office supports manufacturers in the Grand Est region, the Alps, and throughout the country with demanding technical projects: specific equipment, assembly systems, control solutions, measuring mechanisms, and machines dedicated to handling cut parts or manufacturing complex products.
Our engineers, technicians, and specialized staff work with you from the initial design phase through to the final assembly of the machine in your workshop. Each project is fully monitored: definition of your needs, preliminary technical design, validation of mechanical and electrical choices, prototype phase, testing, installation, commissioning, and maintenance support.
Thanks to its comprehensive mastery of the industrial process, SMI is committed to creating a reliable, durable solution for you that meets your quality and precision requirements, whether it is a single piece of equipment or a complete system integrating several automation functions.

Innovative research and design
At SMI, every special machine project begins with in-depth research carried out by our design office. Our employees draw on their expertise in engineering and mechanics to offer tailor-made solutions adapted to your industrial processes and specific constraints.
Using 3D CAD, we carry out the detailed mechanical design of each component, while integrating the electrical studies and pneumatic or automation elements required for your project. This step guarantees precise and reliable machines, optimized for your industrial operations and production needs.
Manufacturing and assembly of your industrial equipment
Our specific equipment and components are assembled in our assembly hall, where our teams also carry out the electrical wiring and programming of automated systems. Each stage is designed to ensure optimal quality, perfectly fitted parts, and easy long-term maintenance.
Installation, commissioning, and support
After completion, our technicians will come directly to your site to install and commission your machines, both in France and abroad. Fine adjustments are made under real production conditions to ensure precision and reliability.
Each piece of equipment is delivered with a complete technical file: assembly plans, electrical diagrams, CAD files, source programs, parts lists, user manual, and maintenance guide.
Our after-sales service also provides comprehensive follow-up, with assistance, preventive maintenance, and advice to extend the life of your machines and optimize your industrial processes.
