Sand Casting (aka Green Sand Casting) is a process in which molten metal is poured into a mould cavity made by forming damp (i.e. Green) sand around a Pattern. The sand used is very finely grained has a clay content (e.g. Bentonite ) of around 12% to enable it to retain sufficient moisture such that, when squeezed, it will stick together but not to the hand.

Dewaxing is done using a steam-dewaxing autoclave or flash fire furnace. Casting: Now the desired molten metal is poured into the pre-heated mold cavity. Cooling: The mold then sits to allow the molten metal to cool and solidify which then becomes the final casting.
