A vibratory press for forming articles of metal powders comprises a frame with vertical guides connected by upper and lower fixed plates, a premolding mechanism kinematically connected to a reactive plate mounted on the vertical guides, to which on elastic shock absorbers a vibrating plate is suspended with an exciter of directed oscillations located thereon, and a vibration bed mounted using elastic supports on the lower plate. Between the lower plate of frame and vibration bed a hard-elastic cushion is mounted and the stiffness of elastic supports of the vibration bed without its loading by the premolding mechanism is selected in such a way that in static condition of the vibration bed without its loading by premolding mechanism a gap is provided between the bed and hard-elastic cushion, which exceeds the value of maximum oscillation amplitude of the vibration bed.
