forming-manufacturing-processes > Non-Ferrous Sand Casting

This process encompasses the use of sand to make disposable moulds into which Non-Ferrous Metal is poured and cooled to form a cast component.

 

Bonding of sand can be achieved using clay as with green sand moulding, or by using resins - typically called "airset" sand moulding.

 

Both of the above moulding techniques achieve variable thickness moulds, where the outer appearance is determined by the container in which the mould was made, or exists. 

 

Multiple die parts and inserts can be used to create complex internal geometries and structures.

 

A similar process is shell moulding - once again using sand, bonded with resins to form a mould. However the moulds produced in shell moulding have a near constant mould wall thickness. The external shape and contour of the shell mould matches the internal, offering favourable cooling characteristics - see "Shell Moulding" for more information.
