Inside This Story:
* The wet tensile test, which determines the tensile strength of green sand's condensation zone, is profiled.
* By using wet tensile testing, foundries facing sand-related defects can monitor the strength of the sand's wet layer to help control sand composition.
While the wet tensile test is very popular in European foundries, only recently have U.S. foundries begun to utilize wet tensile data to improve their sand control efforts by measuring slight changes in both bentonite and molding sand performance.
By utilizing wet tensile testing, foundries can avoid sand-related defects attributed to inadequate strength in ...
