ABSTRACT:
In a closed system a shock pressure wave of a burning gas is used for packing granular mold material loosely distributed around a model. Before the shock pressure is produced, the pore volume of the upper layer of the granular material exposed to the pressure is reduced. Through the pore volume reduction, the active surface of the granular material is increased, so that the gas pressure acts on an increased working surface and, consequently, greater mold hardness is achieved.
