Sand Testing in Foundry (6 Methods that You Should Know)

Strength testing of moulding sand is carried out by using a machine known as strength tester. A well rammed sand specimen having height 50.8 mm and diameter 50.8 mm is used for testing the strength of the sand. As shown in the diagram above, this sand specimen is placed on the universal testing machine (strength tester machine).
