Abstract
The manufacture of lightweight components having high strength properties can be improved in that a bowl-shaped shell (1) has reinforcing ribs (3) made from injected-on plastic in its interior (2) which are connected to the shell (1) at discrete connecting points (11) via perforations (12) in the shell (1), through which the plastic passes, extending beyond the surfaces of the perforations (12).
