Forming and removing mold or core during casting, e.g. of filigree structures, by forming mold or core containing hollow particles, to be collapsed under pressure after casting
A method for forming and removing a mold and/or core during a casting process involves: (a) producing the mold and/or core from a mass containing hollow particles; (b) after the casting has solidified, exposing the mold and/or core to pressure to destroy at least some of the particles and thus collapse the mold or/or core; and (c) removing the mold and/or core residues from the casting.
