- Abstract
A mixture undergoes significant changes during vibro-pneumatic compaction. Three of its main states are noted: initial, intermediate, and liquefaction condition. Molding is most successful when the compaction conditions are consistent with the new physical state of a mixture. For fast and high-quality compaction of alumina-foam polystyrene mixtures a sequence is recommended for the order of interaction between the static component of the compaction effect (pneumatic pressing) and the dynamic component (vibration). Unfired unmilled commercial-grade alumina is used in order to reduce shrinkage during firing, energy consumption during grinding, and to reduce production cost. The transition from casting technology to vibro-pneumatic compaction will reduce the cost of 1 m3 of objects by 40%.
