FIELD: technological processes.
SUBSTANCE: inventions of the claimed group of inventions relate to production of articles by hot stamping. Die with a male die and a female die are used, and an internal support element capable of protruding towards the female die. Surface temperature of the inner support element is reduced to the temperature determined by the formula given. At that, upper limit value is set equal to 100 °C by providing coolant flow through coolant path. Cooling control unit is used to control cooling.
EFFECT: increased strength of articles due to crack cracking suppression.
