The data on the structure formation and mechanical properties of ductile cast iron in castings obtained in shell molds with the use of «in-mold» modifying are presented. The nature of ferrite amount, hardness, tensile strength, yield strength and elongation distribution of castings made of ductile cast iron are defined and analyzed. The obtained results indicate high stability of the quality parameters of castings made of ductile cast iron obtained by «in-mold» process.
