The method involves fastening outer ball-shaped joint element (2) to inner joint element, by passing swivel rod (4) along pivot axis. The swivel rod is connected to tubular blank (10) for applying pressurized fluid (F) to interior (10I) of tubular blank. A mold cavity is attached to/detached from wall of tubular blank due to plastic deformation or centrifugal expansion (E) respectively. An independent claim is included for a push rod of ball-and-socket joint connecting element. |
