In the elliptical bottoms the radius of curvature varies with continuity along the entire internal profile. Generally, the following ratios may be considered for the calculation of dimensions only:
R = 0,9 Di
r = 0,171 Di
Hi = Di/4+h
Ht = S+Di/4~+h
Di h* S
400 ÷ 2100 on request 15 ÷ 60
* on request depending on De and thickness
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.
