Abstract: A method and a device for forming a metal billet into an elongated product body of desired cross-sectional shape and dimension by a combination of die drawing and hydroextrusion from a pressure chamber having a central axis, holding a pressurized working liquid and being fitted with a hydroextrusion die, which are characterized by placing a drawing die of smaller cross-sectional size than the hydroextrusion die in coaxial alignment with the latter at a distance L downstream therefrom whereby the hydroextrusion die and the drawing die form a pair of dies flanking an intermediary empty region; adjusting the distance L to fit the metal and size of the elongated product body such that any stretch of an extruded body passing through the intermediary empty region retains its elastic stability; continuously extruding the billet through the hydroextrusion die to form an extruded intermediate product; continuously passing the extruded intermediate product across the intermediary empty region into the drawing die; and
