09/11/2022Sand Casting is a solidification process. In the casting process, sand is used to build a mould, following which liquid metal is poured into the mould to form a component. Therefore, the microstructure can be finely tuned, such as grain structure, phase transformations and precipitation. However, defects such as shrinkage porosity, cracks and

Once the mould is full, it advances automatically towards a grating as it gradually cools down. Afterwards, the boxes are opened and sand is removed from the metallic parts by means of a pneumatic or mechanical vibration system.

FOUNDRY SAND WASTE Foundries create metal castings for use in the automotive, art, construction, agriculture, and mining industries. In this process, molten metal is poured into a mold, usually made from sand or ceramics. As castings are created, the sand has to be removed and replaced due to abrasion from the high heat and mechanical stress.
