Sand Casting Process

The Sand casting process offers simple medium for production, sand castings are suitable in all Aluminium, Zinc, and Copper Alloys.

The sand casting process is chosen for the production of, small numbers of castings for complex shaped casting requiring intricate cores and large non ferrous castings.

Advantages of sand casting include:

• low tooling costs
• largest casting sizes achievable 
• very low gas porosity is possible
• general versatility of the process is good  

The Sand casting process is the most popular casting process employed in industry. In general the sand used in making sand castings has fine, round grains that can be closely packed to form a smooth surface.

The sand casting process involves pouring molten zinc, aluminium or copper into a sand mould.

The designer should take into account the limitations of the sand casting process such as low casting rates, a 3-5mm minimum wall thickness, poor linear tolerance (e.g. 4mm/m.) and coarse grain size. As well as other considerations such as the finish and machining allowances.
