Manufacturer of springs and wireforms

Specialised in the production of springs, Polyval is able to advise and support her clients, from the search for a solution to the series production, with the realisation of prototypes. Polyval is active in almost all areas of application of the springs and micro-springs.

The production of CML springs, in limited series or large series, affects all areas related to watchmaking, connectivity, microelectronics, etc.


From the strips spring to the micro-spring (wire of 0,06mm), we respond to industrial needs, in almost all materials and all the specialities:

  • Strips spring
  • Wire form spring
  • Actuators
  • Compression
  • Torsion or microscopic


Spring steel, stainless steel, high temperature steel, valve steel, titanium, copper-based alloy, etc.


In-house heat or surface treatments or in subcontracting with specialised companies.
