To produce sand castings, molten metal is poured in to a sand mold and allowed to cool and solidify in to the shape of the mold. Sand castings can be produced in wide range of sizes and are ideal for basic shapes when affordability and quick turnaround are important. Sand castings are not suitable for complex shapes and large production run or for projects where surface finish is of importance.

To produce continuous castings, molten metal is passed through a die which cools and solidifies the metal in to the desired shape. A series of temperature controlled rollers complete the tempering process allowing for control over the grain structure and mechanical properties. As a result, continuous cast products have greater durability and excellent machinability compared to conventional castings. Continuous Casting is ideal for the manufacture of a wide range of semi-finished profiles, including solid and hollow bars round bars, tubes and flats.

To produce centrifugal castings, molten metal is poured in to a spinning hollow mold, on either a horizontal or vertical axis. The liquid metal is forced outward and solidifies in to the shape of the mold while impurities migrate to the ID where they are removed through subsequent machining. This process leads to a casting that is more dense, resulting in a product with greater machinability and less fatigue compared to other casting methods.
