Compression springs of different types and forms; cylindrical, conical, biconical, oval compression springs with or without grinded and/or closed ends. Static or dynamic applications. Wire diameters from 0.04 to 80.00mm.
Wire-forms: round, flat, square or rectangular. Production: small, medium and large series. Wire diameters from 0.1 to 12.00mm.
Extension springs with or without contiguous coils, standard or custom shaped loops. Static or dynamic applications. Wire diameters from 0.10 to 12.00mm. Wire-forms: round, square or rectangular. Production: small, medium and large series.
Torsion springs with a cylindrical, conical or bi-conical body, with simple or complex spring legs adapted to every application. Right- hand or left- hand wounded depending on the load direction. Wire diameters from 0.10 to 10.00mm. Production: small, medium and large series.
Double-bodied springs in symmetrical or asymmetrical shapes. Right- hand or left- hand wounded depending on the load direction. Wire diameters from 0.10 to 8.00mm. Production: small, medium and large series.
Flat Springs made of strip steel of all shapes, stamped, cut and drilled. Thickness of 0.20 to 4.00 mm.
Drawing and realization of tooling. As for the volume, we can produce any quantity you need, whether small, medium or large series.
Life: our production with proper material and production cotrol can achieve long duration up to 30 millions (for valve springs, while normal life cycles 5 millions), 5 millions (for normal springs, if required), or 1 million (for spiral springs, while normal life 20k cycles).
To further assist you in the development and finalizing of your projects, we can handle prototype requests at very short notice.
