Sand Casting for Non Ferrous Castings
Sand casting offers the simplest medium for production of non ferrous castings, by pouring molten zinc, aluminium or copper into a sand mould.
Sand casting is generally chosen for the production of small numbers of castings due to low initial toling costs, and for production of large non ferrous castings or complex shaped castings requiring intricate cores.
Sand castings can be produced in all aluminium, zinc and copper alloys.
Sand casting can be used for small and large production runs and is the cheapest casting process for small production runs.
The huge advantage of sand casting is the production of complex sand castings however the surface finish and tolerances of the finished casting are poor relative to die castings. Production times can also be a lot longer than other casting processes such as gravity die casting and high pressure die casting.
