FIELD: metal working. SUBSTANCE: first, pressure is created in the working cavity of container by penetrating elastic medium with under-die plate bound to the movable power unit of the press. Then the under-die plate is set into the extremely upper position. The resultant increase in pressure is achieved by introducing a plunger into the elastic medium from the side opposite to the action of the under-die plate. One part of the plunger elongates on being heated. EFFECT: wider range of operation capabilities, increased durability of the elastic medium. 2 cl, 2 dwg
