Ht = S + r + h

De	r*	h	de***	r1**	h1	S
250 ÷ 8500	20 ÷ 300	on request	on request (100 ÷ 5000max)	>20÷acc. mold available	10 ÷ 80	2,5 ÷ 45

* on request depending on De and thickness
** on request but depending on the available mold
*** the flanging hole can be off-centre with respect to one ot both axis (da/da1)

Edge preparation

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.
