Abstract
A method of manufacturing a press-formed product includes: capturing the amount of warp in a sheet to be pressed separately for each sheet; and using a die 6, a punch 7, and a movable mold part to press-form the sheet into a press-formed product. During press-forming, the initial position of the movable mold part 9 relative to the die 6 or punch 7 is controlled depending on the amount of warp in the sheet.
