WAY OF WET PRESSING AND DEVICE FOR ITS REALIZING Russian patent published in 2008 - IPC B22F3/02 B22F3/03 B30B15/02 

FIELD: metallurgy.

SUBSTANCE: powder is placed in mould, containing the matrix with internal cylinder and pressing and lower punch. The pressing is made with volatile liquid in quantity 0.2 - 3 of volume pressing pore from the side of pressing punch till the end of the process. At the same time the liquid is fed through the holes in the walls of internal cylinder through all side surface of powder. The mould contains the matrix, composed of tight connection of upper and lower parts, upper and lower punch and piston for supplying the liquid. In the upper and lower part of the matrix it is placed the device for feeding the liquid. The device has the hole as cylinder, made of set of conical washer. On the conical surface of washers are made the reach-through canals with angle of inclination 1 - 89°.

EFFECT: this method let to press the inductile powder without plasticizer and realize the steep.
