A design department with expertise in mechanical engineering and industrial automation

One-Too, solutions made in France for all industries

One-Too solutions are studied, designed, assembled and tested in France. Our after-sales service department is also based in France and managed by experts, in order to guarantee follow-up and support of the highest quality.


The experience of the company gives it a comprehensive view of the whole automotive industry: from design laboratories to deconstruction, One-Too leverages the quality of its analyses, consulting and support to serve original equipment makers and also independent repairers and after-sales networks. For several years now, One-Too has been widening its circle of references by participating in industrial projects in other areas such as aviation, mechanical engineering, energy, railways etc.

The One-Too touch

At One-Too, we do more than just manufacture products. We draw on our creativity and intelligence to find solutions, offer relevant services, develop new processes and assess new modes of organisation.


For us, innovation is the fruit of a complete process, with suggestions, tests and measurements. As a testament to our strong personality, some of our partners even go so far as to speak of the “One-Too touch” when our teams find solutions for their needs.

Half a century of experience

Our know-how: designing and manufacturing a tailored solution to address the issues described by a customer. To that end, the company has a dedicated design office and half a century of experience in the design and manufacture of innovative tools.


One-Too offers the benefit of being a single interlocutor with a strong position and experience that enables it to have a systemic view of each project and be present at each stage: design, models, prototyping, tests, manufacturing, installation, commissioning and training, and also after-sales service.
