METHOD OF FORMING HOLLOW BODY WITH FLANGE

摘要

A method of forming a hollow body having a hollow flange may include performing a hydroforming process to a tubular blank. The tubular blank may be deformed and shaped to form the hollow body and the hollow flange. Subsequent processes may be performed to the hollow flange such as a flattening process whereby confronting internal surfaces of the hollow flange are brought together to abut each other and form a flat flange.
