Abstract
A method for manufacturing a hydroforming member includes the step of providing a blank (). The blank () is defined by blank wall (). The blank () is placed in a die assembly () having a die cavity () defined by a die surface (). The blank () is expanded so that the blank wall () is forced against the die surface () to form the hydroformed member. A portion of the blank wall conforms against a wall-thinning element () positioned along the die surface () to form a removable wall section () in a portion of the blank wall (). The removable wall section () is then removed from the blank wall () to form an opening in the hydroformed member.
