The paper considers the theory and practice of obtaining cast composite materials, their classification and features of the formation of the structure during their synthesis. The results of obtaining parts of responsible purpose from cast composite materials are presented. It is shown that the formation of the transition zone occurs during the infiltration of the matrix melt, followed by its growth during exposure at the synthesis temperature.

The article presents modern data on the materials used to create model kits, the method of their installation for use on any foundries, specializing in the repair and creation of castings by experimental or small-scale batches. The analysis of the used materials, adhesive compositions for their fastening, as well as economic indicators of the costs necessary for their production was made. The properties of glued joints used for manufacturing components of model kits from plastics and its combinations with metal parts are shown.
