A die apparatus for forging a steering rack having a toothed portion and an array of gear teeth. The die apparatus comprising first and second assemblies movable towards each other. The first assembly comprising a first bolster and a tooth die. The second assembly comprising a second bolster, first and second side dies, a center punch, and a third bolster. The third bolster being disposed between the first and second bolsters and being movable relative to the second bolster. The first and second side dies being supported by the third bolster, and the center punch being supported by the second bolster. As the die apparatus closes, the third bolster abuts the first assembly to form a closed forging cavity and then, as the die apparatus continues to close, the center punch penetrates the closed forging cavity to complete the forging of the steering rack.
