SAND TESTING
Molding sand and core sand depend upon shape, size composition and distribution of sand
grains, amount of clay, moisture and additives.
The increase in demand for good surface finish and higher accuracy in castings necessitates
certainty in the quality of mold and core sands.
Sand testing often allows the use of less expensive local sands. It also ensures reliable sand
mixing and enables a utilization of the inherent properties of molding sand.
Sand testing on delivery will immediately detect any variation from the standard quality,
and adjustment of the sand mixture to specific requirements so that the casting defects can
be minimized.
