Abstract: According to the present disclosure, a hot stamping forming method for forming components having various strength according to parts through cooling control for each position includes: setting a required strength for each product part for a sheet supplied into a multi-point forming mold device to which a plurality of forming modules are coupled; adjusting an arrangement of the plurality of forming modules according to the set required strength; and performing cooling control for each part by controlling an amount of cooling air or mist sprayed to the sheet by the air jet nozzle in order to achieve a required cooling speed for each strength part of the supplied sheet, wherein components having various shapes are formable with respect to the supplied sheet in a single mold.
