Provided herein is an apparatus of manufacturing a molding material for use in a method of manufacturing a molding material that can prevent a crack from occurring in the molding material. A cylindrical die (3) is slid downward along an upper hollow compression mold (4) and a lower hollow compression mold (2) with a molding material (35) held between the upper hollow compression mold (4) and the lower hollow compression mold (2). After that, the upper hollow compression mold (4) is moved upward to relatively move the upper hollow compression mold (4) and the lower hollow compression mold (2) away from each other. After a slurry diffusion member (7) is removed, the molding material (35) is taken out.

A steering shaft for a motor vehicle steering system may be used with a steering assistance means. The steering shaft may include an output shaft and a carrier that is connected rotationally conjointly to the output shaft. A worm gear toothing may be disposed on the radially outer region of the carrier. The worm gear toothing may comprise plastic and may form a worm gear for connection to the steering assistance means. Further, the carrier may be formed in one piece with the output shaft.
