Abstract

With this method and the machine for carrying out the method, it is possible to achieve optimum compaction of foundry sand (24) for the production of castings, both as regards the hardness of the mould and as regards gas permeability. Matched to the respective foundry sand quality established by means of a standard test piece using the Brinell ball impression method, flexible settings for a plurality of vibratory pressing phases are possible, in which a plurality of pressing surfaces, such as a frame of a press housing (12), a top plate (13), and a plurality of press rams (14) can be used individually or in groups, simultaneously or in succession with adjustable pressing forces. In addition, unbalance motors (9) of a vibration unit are connected to a continuously adjustable frequency converter so that the vibrations required for the corresponding vibratory pressing phase can be set. <IMAGE>
