The results of experimental investigations were introduced in range of verification of model investigations results (in utilization of supplementary materials) with results of investigations on real materials are presented in this work. To this aim the matrix became constructed with interchangeable little eye made possible extrusion process of real materials at three reduction ratio: [lambda] = 1,5 1,75 and 2,0. Analysis of heterogeneous materials flow process shows, that of principle onto extrusion process exerts kind as well as a way distribution of entrance creators' materials batch. However size of strength of stamp pressure is determined by reduction ratio in main measure.
