Summary:FIELD: powder metallurgy, particular, devices for continuous molding of articles from powders. SUBSTANCE: molding member 4 is given torque, and hot mass is supplied to loading branch pipe 21. Hot mass entering cylinder of unit 18 is distributed to all branch pipes and then to hollow of cylinder of central unit 10. After loading of this unit, opening 16 is closed, sleeve starts extruding the mass from cylinder hollow to die 1 through central opening 9 where it is caught by flights of extruder 26 and supplied at pressure through gap 8 to chamber 27. In nozzle 2, mass is compacted, and wedge surface 5 provides for continuous extrusion of material through zone of pass. EFFECT: extended potentialities of device due to provision of process of molding of hot plasticized powders. 4 dwgt
