I found one website with good metal forming ,metal spinning process as following
Forming of dished ends is achieved in one of three ways:
1. Completely spun - Ends formed using this technique are spun over a tool, which has both the spherical and the knuckle radii. This allows the end to be formed entirely on one spinning machine.
2. Press and Flanging - A contract specific spherical radius is formed using specialist hydraulic Boldrini presses. Following this the required knuckle radius is spun using Boldrini flanging units.
3.Spin and flanging - Unlike pressing, the spherical radius is formed by spinning the plate blank against a fixed forming tool. Forming of the knuckle radius is made in the same way as pressed ends.

Forming of dished ends is achieved inhouse also the clad plates is made here by bonding process done at hydrerabad.
