FIELD: process engineering.
SUBSTANCE: invention relates to machine building, particularly, to production of hollow parts by casting and forging. Casting process involves the use of one or several rods made from reusable monomedia, i.e. sand or salt. Said material if teemed into the mould to produce the semi-finished product with one or several rods to be subjected to applied shocks. Then, the burrs resulted from the forging are removed. Then, one or several rods are removed.
EFFECT: production of parts with different configuration, lower labour and metal input.
