Abstract:
A method and apparatus for forming a hard disk drive base plate with a sequence of progressive forging operations is described. The method may include advancing an initial hard disk drive base plate cut from an extruded sheet through a plurality of stations of a transfer die assembly. The method may also include performing a sequence of forgings on the initial hard disk drive base plate to progressively form parts on a hard disk drive base plate.
