Abstract

In a method for molding formed parts in automatic multiposition presses, using powdered materials having a flowability characterized by a flow time exceeding 60 seconds per 100 g of powder flowing from a 60 DEG standard funnel with a nozzle aperture of 4 mm and a nozzle length of 4 mm, the powdered material having in the mold a filling height to diameter ratio larger than two, the powder is conveyed into the mold by means of filling devices located at a plurality of separate charging stations, pressed at a separate pressing station and ejected at yet another separate station. The filling heights in each mold is subdivided into at least two individual filling heights so that the filling of the mold to these individual filling heights can be carried out at different charging stations.
