Compression springs
We design and manufacture cylindrical helical compression springs in round wire (with diameters starting from 0.10 mm) and square wire.
We use not only specific materials compliant with UNI EN 10270-1, UNI EN 10270-2, and UNI EN 10270-3 standards, but also special materials with specific mechanical properties and high-performance alloys.
We manufacture compression springs both compliant with UNI EN 13906-1, with the tolerances required by UNI EN 15800, and according to customer specifications. Cylindrical, biconical, tapered, with closed or open ends, normal, ground, deburred, right- or left-handed, subjected to heat stabilization treatment, cold settling, shot peening, surface protection treatments, passivation, and other specific treatments requested.
Technical definition
A compression spring consists of a wire or rod wound into a cylindrical helix, generally subjected to stress along the axis of the cylinder with non-contact coils. In this case, the load consists of a force acting along the axis that causes torsional, bending, and shear stresses, the former being predominant. Compression springs, ideally considered as rigid bodies, are generally subjected to a compressive load acting along the spring’s axis. In some cases, they may simultaneously be subjected to a load transverse to the axis. Helical compression springs are generally cylindrical in shape, although other shapes exist: conical, barrel biconical (convex), hyperbolic biconical (concave), or tapered.
