description foundry. SUBSTANCE: method involves destructing sand mixture by exposing to vibration created by alternating electromagnetic field, which results in occurrence of resonance vibration of casting due to the fact that electromagnetic field has vibration frequency coinciding with natural vibration frequency of casting. Anticoincidence of natural vibration frequency of sand mixture and casting causes development of normal and tangential voltages at sand mixture-casting boundary line to result in creation of destructing force. EFFECT: simplified method and increased efficiency in knocking down of casting from casting mold. 1 dwg
