Testing of different types of sand

This course provides a practical understanding of testing different types of moulding sands used in foundry operations. Participants learn about the properties and characteristics required for good quality moulding sand. The course covers different types of sands such as green sand, dry sand, core sand, and facing sand. Participants learn how to collect, prepare, and test sand samples correctly. It explains important tests for moisture content, permeability, strength, grain size, and clay content. The course also introduces equipment and methods used for laboratory and shop-floor sand testing. Participants learn how test results affect mould quality and casting performance. Common sand-related problems and their causes are also discussed. The course helps participants understand how to control and maintain sand quality during production. Overall, it builds practical skills for producing sound castings with fewer moulding and casting defects.
