Sand Casting
 Sand, combined with a suitable binder can be packed tightly about a pattern. When the pattern is removed, a cavity that retains the shape of the part remains.
Sand casting is one of the most popular and simplest types of casting that has been used for centuries. It allows for smaller batches to be made compared to permanent mold castings at a very reasonable cost. This allows manufacturers to create products at a low cost and permits small size operations.
Sand casting process is used to produce ductile iron castings and grey iron casting.
