Metal Fabrication Comparison Chart | Metal Casting Chart
Investment Casting vs. Sand Casting. Sand castings are made by creating a negative in a bed of sand to create the cavity for casting. A sand shell creates a rough exterior to castings. Typical surface finish of sand castings are 250 Ra as cast, and need extensive work afterwards to create a surface finish that is acceptable in most applications.

A blow caused in an aluminum casting by high moisture content of the sand is shown in figure 206. To remedy this situation, the sand should be mulled to break up the clay balls. If the sand contains too many fines, it will have a low permeability and the moisture or gas will have a difficult time flowing through the sand away from the casting.
