sand casting process

Sand Casting Aluminum. Sand casting aluminum with a charcoal furnace Sand casting is the process of casting molten metal into a mold cavity formed in sand There are really only two basic requirements that the sand has a cavity in the shape of the object you wish to cast and that there is a channel you can pour metal into that will lead to the cavity

The dimensional accuracy can be increased. Use of uniform thicknesses in a casting, where possible. Uniform thicknesses lead to uniform cooling and solidification. This leads to stress free and distortion free castings. Heavier sections cool more slowly, and may have shrinkage cavities, porosities and large grain structures.

Technical Guide - Aluminum Sand Castings & Rapid Protoypes

When any casting design is being considered, it is important to involve the foundry as early in the design process as possible. Even if the specific type ofcasting (sand, die, V-Process, etc.) has not been determined, working with one or more foundries will always be beneficial to determine the best casting process for the application.
