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.
