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
- 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.
- Medical and dental
- Machine tool
- Printing machines
Our services are for you.
Spring production from the following raw materials:
High temperature steel
Wire from 0.06mm to 6mm
2 laser cutting machines for sheet metal with a thickness from 0,05mm to 2mm (allows the production of prototypes)
This working method can also be used for specially shaped springs
2 wire electrical discharge machines Agie Charmilles : 1 Robofil 100 and 1 SLP 240, 5µm cutting precision, allowing combinations with laser cutting
11 micro-spring machines, wire from 0.04mm to 0,4mm
26 spring machines, wire from 0,4 to 6,00mm
