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 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
Material
Spring steel, stainless steel, high temperature steel, valve steel, titanium, copper-based alloy, etc.
Treatments
In-house heat or surface treatments or in subcontracting with specialised companies.
