Abstract
A method for manufacturing a stamped part, such as a bipolar plate for a fuel cell, includes the steps of: providing an original model of the bipolar plate; and performing a compensation process on the original model, the compensation process including a two step morphing process based upon a prediction of spring back. The two step morphing process provides a compensated model of the stamped part. A compensated die face may be created based on the compensated model of the stamped part. The stamped part manufactured with the compensated die face has spring back compensation.
