Difference Between Sand Casting and Die Casting

Both methods of casting use a pattern or mold to create the cavity, then molten metal is used to fill the cavity creating the desired part. That is where the similarities between the two methods end. In the sand casting process a pattern, or mold, is needed to create the empty cavity within the sand to create the shape of the desired part. This means that the pattern could be made out of a variety of materials,
