FIELD: process engineering, engines and pumps.
SUBSTANCE: proposed method consists in making a cavity between mould parts walls made of at least two parts and repeating the shape of stator case. Cores made from soluble material are rigidly jointed to at least one part of said mould, and held at a distance from aforesaid wall to mate free spaces to be made inside the case. Said cavity is filled with metal alloy powder to be sintered by hot isostatic moulding. Rods are removed by dissolution and the case, thus produced, is removed from mould.
EFFECT: higher accuracy and strength.
