Sand Casting

Josh Ricketts says:

Sand Casting - Is the process in which a sand mould is used to create a product or component from metal.

The process is shown below. The pattern is separated into two halves. Firstly the pattern, usually made of wood, is placed down and sand is poured on top. This is then compacted and the other half of the pattern is processed. Once this is complete, the pattern is removed, and the mould is finished. A gating system is created to allow the liquid metal to pour in and then the mould is cooled. Removing the moulds leaves the product and the gating system (the spruces) is cut off, leaving the finished product.
