Aluminium is one of the few metals that can be cast by all of the processes used in casting metals: Die casting, permanent mold casting, sand casting (green sand and resin sand), plaster casting, investment casting, and continuous casting. Other processes such as lost foam, squeeze casting, and hot isostatic pressing are also mentioned.
There are many factors that affect selection of a casting process for producing a specific aluminium alloy part. The most important factors for all casting processes are:
Feasibility and cost factors
Quality factors.
