Sand Castings

What is Sand Casting?

In sand casting, the mold is formed around a pattern by ramming sand, mixed with the proper bonding agent, onto the pattern. Then the pattern is removed, leaving a cavity in the shape of the casting to be made. If the casting is to have internal cavities or undercuts, sand cores are used to make them. Molten metal is poured into the mold, and after it has solidified the mold is broken to remove the casting.

Benefits of Sand Casting

The main advantages of sand casting are versatility (a wide variety of alloys, shapes, and sizes can be sand cast) and low cost of minimum equipment when a small number of castings is to be made. A minimum wall thickness of 3.8 mm (0.15 in.) normally is required for aluminum sand castings.
