Abstract
A process and apparatus for producing a brake drum or a brake disc include a carrier component formed of a light metal alloy which can be easily cast and machined and a friction lining component formed of a light metal alloy reinforced by short non-metallic fibers or particles by casting a first one of the components in a mold, cooling the cast component to achieve dimensional stability, casting the other component onto or around the first component, the components being designed to interlock mechanically as a unitary composite structure after cooling. The casting materials may be introduced into the die in a molten state or a thixotropic state. Core pullers are provided to create space in the die cavity for the second component after the first component has been cast and cooled to a dimensionally stable state.
