description: The aim of the work was the development and implementation of proposals to combat marriage on shrinkage defects of a typical casting from grey cast iron/ 
To achieve this goal, the following main tasks were formulated and solved: to develop proposals for improving the design of the gate-feeding system and to verify their effectiveness through modeling; to consider the possibility of combat-ing shrinkage defects due to proposals for changing the chemical composition of cast iron with the existing design of the gate-feeding system.
Produced collection and comparative analysis of statistical data on the quality of casting "housing cage." The reasons for the formation of shrinkage defects by the existing technology were confirmed by the results of modeling the processes of casting, solidification of the casting and the formation of shrinkage defects using the PolygonSoft program.
The manufacturing technology of the âHousing-websâ casting from cast iron SCh30 and SCh15 is analyzed.
Developed and confirmed by the simulation results of the hardening process, proposals for improving the design of the gate-feeding casting system "Housing of the holder" of cast iron SCh30.
An alternative was the proposal to change the basic chemical composition and the introduction of nickel as a perlitizer.
