Design guidance can be fairly general - this is because sand casting is a very versatile process with the ability to create highly complex shapes and internal geometry. The finer details of design should involve the foundry, but the earlier you can get advice on how best to adapt or tune a design for sand casting the better. Radii

The sand casting process involves the use of a furnace, metal, pattern, and sand mold. The metal is melted in the furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern. The sand mold separates along a parting line and the solidified casting can be removed.
