摘要:
The invention relates to a method for producing a component of a synchronization device for manual transmissions, in particular a synchronizer ring (1, 2, 3), wherein a round blank produced from metal is formed in a plurality of forming steps. In order to simplify the production process, it is proposed according to the invention that at least one of the forming steps is a hot forming step in which the round blank is partially heated to a temperature of more than 600° C. and is then formed in the partially heated forming portion.
