Abstract
Method and apparatus for forming a first and a second component disk which are bonded together to produce a bonded composite disk, wherein a first mold for forming the first component disk includes first mutually concentric components cooperating to define a molding surface for forming a bonding surface of the first component disk, while a second mold for the second component disk includes second mutually concentric components cooperating to define a molding surface for forming the bonding surface of the second component disk, and wherein the first mutually concentric components are dimensioned such that at least one of first annular boundaries between adjacent ones of the first mutually concentric components, which boundaries are located on the molding surface, has a diameter different from that of the corresponding second annular boundary between adjacent ones of the second mutually concentric components.
