FIELD: devices used for blowing-out of various geometric forms, mainly of the shell structure, provided of sublimation materials. SUBSTANCE: the extrusion plant has a frame with guides, carriage with a hydraulic motor, mould, extrusion mechanism, upper blow mandrel with a feed mechanism and a cutting mechanism. The moulds have a feed, release and joining mechanism comprising a hydraulic cylinder. The extrusion mechanism is provided with an extrusion head. The plant is provided with a regenerator of polymeric crumb, lower blow mandrel mechanism, protective guards, switches, valve, pressure gauges, three distributors of batch charges and a charging trough for discharge of parts. The protective guards prevent penetration of a human to the operating mechanisms of the plant in the process of execution of operation. The frame is provided with a heating device. The guides couple the carriage to the joining mechanism of the moulds moving due to engagement with the hydraulic cylinder. EFFECT: enhanced quality of manufacture of various articles with various geometric forms at a reduced cost. 1 dwg
