Abstract

A process for heating stamped metal discs or other plates, or rings, having radially extending tongues, prior to the forming of the stamped blanks into spring retainer members and the like, the process comprising electrically connecting together the tongues of a stamped blank at or near their free ends, and then heating the stamped blank to a predetermined desired temperature by electrical induction heating. The process may be carried out with the stamped blank supported in a press which is used to deform and quench the blank subsequent to it being heated to the predetermined temperature. The press accommodates a contact ring for electrically connecting the tongues under pressure and means for rotating the stamped blank during the induction heating of the blank.
