  • Publication number: 20220212242
    Abstract: A method for a hot press forming apparatus and a hot press forming apparatus (102; 202) for forming a blank (104), the hot press forming apparatus (102; 202) comprising a first die (106; 206) and a second die (108), wherein the first die (106; 206) has at least one die cavity (110; 210), and the second die (108) has at least one die protrusion (112), wherein the hot press forming apparatus (102; 202) is configured to, by means of the first and second dies (106, 108; 206, 108), press form the blank (104) placed between the first and second dies (106, 108; 206, 108). At least one of the first and second dies (106, 108; 206, 108) has a draw radius (116; 216), wherein a member (118; 218) is attached to a die (106; 206) which has a draw radius (116; 216). At least a portion (119; 219) of the member (118; 218) is positioned adjacent to or on the draw radius (116; 216).
