ABSTRACT:
Numerous embodiments of a method to form a base plate for a hard disk drive are described. In one embodiment, a blank base plate is advanced through plurality of die stations and parts of the base plate are press worked to form a disk drive base plate. In one embodiment, the blank base plate may be press worked by stamping the base plate with a progressive die assembly. In an alternative embodiment, the blank base plate may be press worked by stamping the base plate with a transfer die assembly.
