Rings

Rings

Typology: wire rings in simple or complex shapes produced by our vast range of CNC Wafios® torsion and bending machines, Bihler® bending machines, and ring machines with welding unit and automatic press with transfer included.
We usually use round wire, and on request wire in square or rectangular sections. We are specialised in the manufacture of rings for piston seals, sealing rings for valve assemblies, rings for circle covers and rings for friction assemblies, both in small (tens of pieces) and large series (millions of pieces).

Measurement: items of wire thicknesses from 0.10 mm to 12.00 mm.

Materials: currently the following materials are being used:

  • Carbon steel wire of classification: SL, SM, SH, DH according to norm EN 10270-1, also in pregalvanised and Bezinal® versions.
  • Oil pretempered steel wire FD, TD, VD Cr-Si according to the norm EN 10270-2.
  • Inox steel wire of types 1.4310, 1.4310 HS, 1.4568, 1.4404 according to norm EN 10270-3 and of type 1.4539 according to norm EN 10088-3
  • Iron (steel with low carbon content) according to norms EN 10016-2 and EN 10277-2
  • Copper alloys: Cu-Be, phosphorous brass and bronze according to norm EN 12166

Annual production capacity: 100 million pieces.
