The main problem at manufacturing products by deformation of waxy powder materials used to produce investment patterns is the lack of uniformity of physical-mechanical properties of the resulting compact, which results in an uneven elastic response of the compacted material. The results of experimental determination of the parameters of the process of obtaining an extended compact by extrusion forming are given in the paper It is determined, that change of fractional composition of materials and velocity of movement of a punch can regulation of final properties of extended compact for obtaining the predicted values of their elastic response. The solution variants of problem of elastic response are proposed on the basis of experimental data. Obtaining an extended compact element with the most uniform elastic response makes it possible to predict the accuracy and take into account its dimensional parameters in the design of the press equipment.
