Relevance of the work is the need to develop methods for molding ceramic of nanopowders. The main objective during compaction of such powders is to get a quality product of complex shape with a uniform density distribution in terms of consolidation and to preserve the grain size in the nanoscale. This requires to reduce friction force during compaction without using plasticizers and lubricants and provide the purity of sintered of nanopowders. One of these methods - pressing the collector method, developed and patented in the TPU. Base on the principles of the collector was modeled compaction mold for compaction of cylindrical compacts with twelve alternating, oppositely-moving parts of the passive shaping surface with sliders, twisted at an angle of 36?. The process of compaction of the powder simulated by finite element method (FEM) software package COSMOS complex of solid modeling SolidWorks. In the model of proposed by the spiral variants of realization the collector is able to observe a similar zigzag bending of the layers of the peripheral zone. However, this distortion with the same number of passive formative elements is not as essential as a collector compaction method, and the local density gradients are less than the collector pressed. The results of comparative simulation showed that the relative density gradient along the vertical axis of compaction is reduced to 80-90% when compared with conventional static compaction and reduced to 24-43% when compared with collector compaction. The change of twist angle of the collector slide of spiral type in the range from 0 to 70? the dispersion is decreased monotonically, and in the range from 70 to 80?the dispersion is decreased immediately.
