Ht = S + R + h
De R h* S
>8500 ÷ 12000 Di/2 on request 2,5 ÷ 60
* on request depending on R and thickness
h = it will not be straight but it will follow the forming radius
Every request will be subject to a feasibility study. Depending on the required characteristics (dimensions, material, thickness) S.I.F.E.A. might propose different workings and cold or hot forming. If a dimension has a value out of indicated ranges, please do not hesitate to contact S.I.F.E.A. for a specific evaluation.
