FIELD: metallurgy.
SUBSTANCE: invention relates to foundry field. In rod case there are formed holes by means of location in case volume of corresponding parts of form tools of specified form. After case forming it is abstracted form tool from rod case in the same plane. In case holes there are located prefabricated cast-in element. In each cast-in element it is implemented channel, form of side wall of which corresponds form of side surface of work member blade of centrifugal pump.
EFFECT: it is achieved simplification of rod manufacturing process.
