Abstract
The invention relates to mechanical engineering technology, namely to processes for manufacturing parts by wet pressing of metal powder.The process for wet pressing of metal powder includes placement of a mixture (1) of metal powder and liquid in a mold, which consists of a matrix (2), in which are made capillary (3) and drainage (4) channels, a mobile (5) and a fixed (6) plunger, a piston (7) and a rod (8). The process also includes compressing of the mixture (1) by moving the mobile plunger (5) and the piston (7), concomitantly is carried out the vacuum compaction through the channels (3, 4) and are applied pulses with a force, whose value does not exceed 0.2% of the specific pressing force value.
