FIELD: metallurgy.
SUBSTANCE: invention refers to foundry engineering. The method consists in implementation of a casting mould with a gate channel part of which is made in form of a spiral. Behind the spiral section the gate channel is divided in plane of perpendicular axis of spiral into two channels for supplying melt to peripheral and central zones of a working cavity of the casting mould correspondingly. To perform inter-mould modified treatment of melt there is used a mixture containing a component, density of which exceeds density of melt or with bigger dimensions of particles, designed for modification of part of melt filling the peripheral zone of the working cavity and containing a component, density of which is less, than density of melt or having smaller dimensions of particle; it is and designed for modification of part of melt filling the central zone of the working cavity.
EFFECT: differentiation of properties of various parts of casting corresponding to their functionality.
