As elaborated by IQS Directory in their insightful piece “Sand Casting,” sand casting has a rich history dating back to 1000 BCE. Despite its ancient origins, continuous improvements in process controls, material options, and tolerance capabilities have made sand casting a cornerstone in modern manufacturing.
Sand casting entails pouring molten metal into a sand mold with a hollow cavity of the desired shape. Once cooled and solidified, the casting is freed from the sand mold. This method accommodates various materials such as metal, concrete, epoxy, plaster, and clay.
Parts produced through sand casting span a broad spectrum of sizes, weights, and complexities, utilizing different metals. Notably, sand casting significantly reduces casting costs compared to metal mold processes, where mold machining constitutes a substantial expense.
The choice of sand type in sand casting hinges on whether the sand will be reused or discarded. Green sand casting allows for mold reuse, while dry sand casting necessitates sand disposal.
Sand casting is indispensable for metals with high melting points like titanium, steel, and nickel, making it favored by aerospace and automotive industries for cost-effective, small-scale part production.
