Abstract
In a mold producing foundry machine generally according to the 'Disamatic.RTM.'-principle a method of compensating for relatively slowly varying compaction properties of the mold particle material without compromising the geometrical requirements for repeatedly fixed placements of the pattern plates defining the mold chamber before the shot, comprises previous establishment of a beneficial set of starting parameters for shot and pressing of the mold to a fix terminating compaction force. The percentual volume reduction from the fixed starting volume to the terminating volume of the compacted mold--yielding the mold compressibility--is compared to the previously established beneficial reference value and the succeeding shots are adaptively controlled to compensate for the realised offset in compressibility by especially regulating the shot pressure, duration and fluidization parameters in a cyclic sequence securing steady reduction of the offset value to be within acceptable margins. The invention also comprises a related apparatus.
