Automation of process to compact sand in sand-casting
Industrial Problem for Innovation / / Featured
Sand casting is a metal casting process characterized by using sand as the mold material. The sand is typically contained in a system of frames or mold boxes. The mold cavities and gate system are created by compacting the sand around pattern. Sometimes this compaction of sand around pattern is done by pressure of feet of worker. Worker jumps over sand and thereby compacting the sand around pattern that in turn results in creation of mould in sand. This manual process has several drawbacks like immense fatigue of the worker, non-uniform compaction of sand, low productivity etc. Due to non-uniform compaction of sand around the pattern in a typical manual compaction of sand, several defects appear in the casting. Industry of our region needs a low-cost automation that can automatically do desired compaction of sand around a typical pattern. Please watch attached video to understand the need.
