Abstract
Methods for manufacturing a press formed article ( ) may include half die cutting a substantially flat material ( ) by press forming, thereby forming a first processed material ( ) having a first intermediate press formed article ( ) defined therein. The half die cutting step is preferably performed while simultaneously compressing the central portion of the material in order to induce outward plastic flow within the first intermediate press formed article. These methods optionally may include pressing the first intermediate press formed article back into the first processed material, thereby forming a second processed material ( ) having a second intermediate press formed article ( ), and separating the second intermediate press formed article from the second processed material, thereby forming a final processed material ( ) and an unfinished press formed article ( ).
