description: The aim of the work was the development and realization of proposals to eliminate shrinkage defects of the casting made from ductile iron. Comparative analysis of statistical data on the quality of the casting was performed. It was established that fluctuations in casting temperature in various melts are insignificant and, therefore, it does not have a significant effect on the degree of damage of castings by shrinkage defects. A preliminary conclusion is made about the predominant influence of the design of the gate-feeding system on the quality of castings and the need for its improvement. The proposals for improving the feeding system in terms of changing the shape of the feeding heads and of the location of refrigerators were developed and pretested in the process of modeling the solidification process of the casting. As a result of the implementation of the developed proposals, a casting is obtained in which the degree of damage by shrinkage defects is significantly reduced, which allows to reduce the cost of defect correction (cutting and welding).
