Least Expensive in small quantities (less than 100). Ferrous and non - ferrous metals may be cast. Possible to cast very large parts. & bull, Least expensive tooling. Use when strength/weight ratio permits.Tolerances. Surface finish and low machining cost does not warrant a more expensive process.

Deally suited for small and medium quantities sand castings are produced in alluminium based alloys up to a weight of about 80 kg.
