The production of bimetallic parts makes it possible to realize in them a set of operational and mechanical characteristics inherent in iron-carbon and non-ferrous alloys. The implementation of the process of the developed technology for the formation of bimetallic casting with a rigid steel frame and a surface made of non-ferrous alloys, which have greater plasticity and electrical conductivity than the frame material, is possible through the use of a modernized investment casting method. The stage of manufacturing the surface of the investment casting model, which is formed by pressing the wax powder into the gap between the mold and the steel frame, is subject to change, which makes it possible to increase the dimensional and geometric accuracy of casting by eliminating thermophysical defects. The problem in implementing this approach is the elastic response of the material. This work solves the problem of determining the technological parameters of the formation of the waxy surface of the melted model of a bimetallic casting.
