Aluminum alloy casting is a manufacturing process that involves pouring molten aluminum alloy into a mold, allowing it to cool and solidify into the desired part shape. It is widely used in industries such as automotive and aerospace. The main casting methods include sand casting, metal die casting, die casting, and low-pressure casting, each suited to different levels of complexity and production volumes—for instance, sand casting is ideal for large components, while die casting enables high-precision, high-volume production.
