ABSTRACT:
In a process for compacting foundry mold making material, and more specially wet foundry sand, by the violent effect of gas pressure on the free surface of the mold material heaped on to the pattern, the compacting effect may be made better and the height of extra material on the pattern may be better controlled by placing a gas-permeable further or auxiliary mass on the free surface of the mold material. The further material is made up of separate pieces of material that may be moved in relation to the surface of the mold material, the gas pressure taking effect on the free surface of the further mass. The further mass may be used in compaction processes in which the pressure wave is produced by expansion of gas from a receiver and processes in which the wave is produced by an explosion.
