Elastic response of the material is the significant disadvantage during process of formation of compacts from disperse polymer materials used in special types of casting. Certain difficulties in view of this effect come out from volume anisotropy of properties of the obtaining compacts and poor precision of finite size prediction. This paper presents results and analysis of data obtained during experiment. Different variants of elements’ positioning in former block, where it may be obtained by pressing, are considered. By varying of speed of compacts forming is achieved reduction of anisotropy, that allows to predict the finite size of forming product, which is important in the design of equipment for press forming.
