Metal foundry casting is a manufacturing process by which melted non-ferrous or ferrous metal are poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solid casting is then ejected or broken out to complete the process. Casting may be used to form hot liquid metals or various materials that cold set after mixing of components (such as epoxies, concrete, plaster and clay). Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods.

The casting process itself is subdivided into two distinct subgroups: expendable and non-expendable mold casting and the casting types are sand casting, investment casting, continuous casting, vacuum casting, centrifugal casting and others . Though sand casting and investment casting generally involve roughly the same steps such pattern making, molding, melting, pouring, ejection, cleaning, fettling, and inspection, they do have major differences in terms of cost, weight and intricacies of the desired finished products. Being in the foundry industry for more than 50 years, Hunta foundry has horned its expertise in both sand casting and investment casting.
