The article represents the main principles of the theory of pressing process of products made of MR fiber material. It is showed that the equations of ideal (excluding external frictional force) pressing process of products made of MR material are represented as power function of pressing pressure depends on density of porous body. The power function of the hardening of the wire material in compact is determined. It is established that the ideal pressing process contains two stages in the range of relative densities of porous bodies [0.15; 0.7]. The main equation of pressing process of products made of MR is obtained. Experimental proof of hypotheses and assumptions confirmed their validity.
