Sand Casting

Sand casting is a very versatile process and can produce castings of extreme complexity in a wide range of aluminium alloys. Interest in light weighting and improvements in the technology of sand casting has driven the average weight and size of aluminium sand castings upward, with many parts weighing over 50 kg and with some parts as large as 100 m 3.

Coatings for moulds and cores

2000-1-1 · Metal penetration, sand burn-on and carbon defects occur most commonly with ferrous metals, due to their high casting temperature, high density and the reactivity of their oxides to silica sand. Conversely, moulds and cores for aluminium alloy castings rarely display metal penetration and burn-on so coatings are often un-necessary.
