In producing casting molds or mold parts (19) by compacting mold sand in a molding chamber (8) between two pattern plates, the geometrical parameters of the molding chamber (8) are sensed and/or computed, such as by using position sensors (11a, 12a) and a timer/controller (6b) capable of computing, before and after the compacting step, and the values obtained are used in conjunction with desired values of some post-compacting parameters to make adjustments to the starting conditions, before the next mold or mold part is produced. In this manner it is possible to achieve a continuous correction of e.g. such parameters as the compacting ratio, determining the hardness of the produced mold or mold part, and the linear dimension of the mold or mold part in the longitudinal direction of a mold (not shown), in which the mold or mold part is to be included, determining the position of the point, at which molten metal is to be poured into the casting spaces (not shown).
