Abstract
In this connection, studies aimed at improving the obtaining process of high-quality castings of mining equipment are relevant. At the same time there is a need for studying physical and mechanical relationship of mixes in which a resin from various factors is bonding (rate and time of thermal impact for mixture, rate of the enclosed load of mixin the course of forming, etc.). In particular, there is reasonability of increasing the mixture pressure in the manufacturing process of a mold [1-3].
