A method and corresponding device for compacting a powder material into a homogenous article. The method includes the steps of, placing the powder material in a molding cavity connected to a gas source, blowing gas into the lower end of the molding cavity so that the particles in the powder material are suspended in a gas stream, sealing the upper end of the molding cavity by an upper pressing punch, connecting the lower end of the molding cavity to a vacuum source, sealing the connection to the vacuum source by moving a lower punch relative to the lower end portion of the molding cavity, and thereafter compacting the powder material with the help of the pressing punch. The apparatus for performing the method includes a molding cavity having sidewalls, an upper and lower punch moveable within the molding cavity an opining in communication with the molding cavity for blowing gas into, and sucking gas out of the cavity, wherein the lower punch is moveable between a first position in which an upper end surface of the punch is located below the opening, to a second position in which the opening is covered by a sidewall of the lower punch.
