FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, particularly, to production of formed blanks of preset shape. Blank with medium for hydrostatic forming is placed inside the female die. Simultaneously, blank temperature is cyclically varied to apply pressure to said blank and to said medium. Note here that hydraulic forming fluid is used that features viscosity in liquid state exceeding 103 rests at cyclic variation of temperature.
EFFECT: uniform application of pressure to the blank.
