Abstract

The vibratory compaction of dry sands is one of the principal procedures for the lost foam casting (LFC) process. The sand fills all internal pattern cavities and packs tightly around the coated and dried foam patterns to provide support. The pressure produced during vibration is deemed important, since its un-even distribution may result in undesirable deformation of the foam pattern. Pattern deformation affects the dimensional precision and accuracy of the castings.
