Straightening and cutting

  • The wire loaded onto the reel near the machines is unwound by centrifugal straightening with an ISO46 hydraulic oil bath mandrel.
  • The dowels are made of Teflon or bronze in order not to damage aesthetically and functionally the surface of the processed wire.
  • The cutting operation is carried out by a system of knives which cut the treated diameters at 90° with no further processing needs.
  • The flat wire is straightened using a roller system.


  • Bending can be done directly from the coil wire or on semi-finished cut products, depending on the technical-economic evaluation.
  • For the products which have particularly complex bends, the processing is completed with a second stamping phase.
  • Small details – such as studs – are integrated into the same cycle.


Usually used for high-volume products, stamping in the press area (up to 150 t) allows the shaping of components using a mould, designed, manufactured and maintained internally or externally, depending on the workload of the in-house workshop.


The assembly process of semi-finished products is carried out using tack welding, which consists in melting two components with an electric shock through two copper electrodes, and allows solid parts to be permanently joined together.
This process allows the various components to be joined together quickly, cleanly and in a more aesthetically pleasing manner. The department boasts punching lines for flat grids in large production batches, robots for hob grids, and other manual or semi-automatic punching machines.
