Based in Courgenay in the Swiss Jura, at the heart of an industrial fabric historically linked to mechanical precision, Ressorts Industriels\u00a0SA\u00a0, or RISA for short, has been designing and manufacturing springs since 1959. Its precision springs are used in the most demanding sectors\u00a0\u2013 watchmaking, of course, but also medical technology, microtechnology, electrical engineering, aerospace and robotics.<\/p>\n

 <\/p>\n

RISA\u2019s technical expertise means that it can meet highly stringent specifications, while its unique know-how in the production of custom springs offers significant potential for growth.<\/p>\n

 <\/p>\n

All types of springs<\/strong><\/p>\n

 <\/p>\n

The company has expertise in all major spring types: compression, extension and torsion springs, wire forms, flat and stamped springs, as well as various components for use in watch cases and movements. This versatility enables it to support its customers from the design phase through to industrial production, while offering solutions tailored to the specific constraints of each application.<\/p>\n

 <\/p>\n

Although they often go unnoticed by the public, springs are found in countless everyday objects and technical devices. For all their apparent simplicity, these components play a vital functional role: their dynamic behaviour allows them to store and release energy, so contributing directly to the operation of the mechanisms in which they are used. In fields such as watchmaking and medtech, where precision and reliability are key, the design and manufacture of these parts demand a very high level of quality.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

From watchmaking to medtech<\/strong><\/p>\n

 <\/p>\n

Over the years, the company has developed its expertise to build real technological bridges between the watchmaking market\u00a0\u2013 historically its core business\u00a0\u2013 and the medical technology sector. Its ability to work with extremely fine wires and produce complex geometries has been a major asset in this process.<\/p>\n

 <\/p>\n

This expertise naturally translates into the manufacture of components for orthodontic instruments, surgical tools and respirators. Meanwhile, these skills continue to serve the needs of the watchmaking industry, particularly for movement, case and clasp components.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Quality closely monitored<\/strong><\/p>\n

 <\/p>\n

Dynamic test benches and unit vision inspection systems are used to check the conformity and repeatability of the parts produced\u00a0\u2013 two essential criteria for devices where failure is not an option. The knowledge acquired in alloy selection, heat treatments and surface finishes also helps to ensure operational excellence in the approach to these manufacturing processes.<\/p>\n

 <\/p>\n

While these synergies between watchmaking and medtech offer valuable growth opportunities, they also increase organisational requirements. For an SME like RISA, this development presents both a challenge and the opportunity to further raise its standards and consolidate its position as a trusted partner for high-value-added industrial applications.<\/p>\n

 <\/p>\n

It should also be noted that the company has a structured management system certified by a number of internationally recognised standards: ISO\u00a09001 for quality management, ISO\u00a013485 for medical devices, ISO\u00a014001 for the environment and ISO\u00a045001 for employee health and safety.<\/p>\n
