forming-manufacturing-processes > Ferrous Sand Casting

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

 

Sand can be bonded with organic matter such as clay as with green sand moulding, or with resins as with airset or resin bonded sand moulding.

 

In both of these processes variable thickness moulds are produced - the internal contours matching the component to be cast, and the external typically following the contour of a box or container.

 

In sand casting multiple die parts including inserts can make up the finished die prior to metal pouring.

 

Airset or resin bonded sand moulding is not to be confused with true "Shell Moulding" - although similar, in the fact that resin bonded sand is applied, shell moulding differs in the fact that the shell mould is almost constant thickness, showing the contours of the component to be cast both on the inside and outside of the airset sand mould.
