摘要

Production of a bushing on a hollow profile (1) comprises forming slits in a perforated edge (3) before converting into plates (5) pointing radially to a middle hole by bending the plates. Preferred Features: A hole (2) is produced at the same time as the slitting of the edge. The hollow profile has two half shells, one of which has a hole and slits before joining. The hollow profile is produced in an inner high pressure deforming tool using a fluidic inner high pressure.
