Composite gear blanks are manufactured by placing a rigid centerpiece in a mold, optionally inertizing the mold, filling the mold by adding a liquid reactive mixture around the centerpiece, applying static pressure to the mold and polymerizing the reactive mixture so as to form a plastic outer part surrounding the centerpiece. The composite gear blanks thus made have improved values of normal and shear adhesion strength both at room temperature and at elevated temperatures of up to 120&#xb0; C. and are particularly suited for making worm gear parts of automotive electronic power steering systems.
