摘要： A powder box, an arrangement for a powder box comprising an insert and a method for filling powder into a cavity formed in a die. Gas is supplied to a powder box, which is movable toward and away from a position just above the cavity. The gas is supplied through a permeable plate, which is arranged on at least one insert and which faces the interior of the powder box, so that particles of the powder in the powder box are movable relative to each other. The fluidisation of the powder shortens the filling time and results in an even particle size distribution in the cavity.
