ABSTRACT:
An explosion treatment apparatus useful for confined shock exposure of materials as for removal of sand cores from finished castings and, in particular, cores in permanent mold castings in which a horizontally axised index device successively presents plural and substantially similar cavities to a position at which sealing, evacuating, fueling and ignition occur. This results in an explosion which occurs upon closure of each chamber. After the confined explosion, the cavity is opened and all cavities are indexed so that the fired cavity can be unloaded, the previously unloaded cavity can be dumped, the next adjacent cavity can be reloaded, and the reloaded cavity is presented to closure.
