The sow mold is named after the shape of a female pig (sow), which it resembles with its tapered shape and large belly. The molten aluminum, which is typically heated to a temperature of around 750°C (1382°F), is poured into the sow mold and allowed to solidify. The resulting ingot is then typically used to produce various aluminum products such as sheet metal, extrusions, and other products.
Sow molds typically come in various sizes, ranging from 5-10 tons up to 50-70 tons, depending on the specific application and the size of the desired aluminum ingot. The molds are also designed with various features that enable easy handling and transport, such as lifting lugs, forklift pockets, and other attachments.
