Sand Casting. Sand has been around for millennia so it s not surprising that sand casting has an equally long history. It is a type of casting within the gravity casting process category because the molten metal is poured from a ladle into a mold made from sand using gravity rather than high-pressure injection to fill the die.

Die Casting vs. Sand CastingWhat s the Difference
Sand casting is a much easier and cheaper process but can become cumbersome when scaled up as each part needs a new sand mold. Sand casting is therefore best for low volume projects where only 1-1000 castings must be made. Finally if the price is of concern sand casting is the best option available. It is an easy inexpensive and effective
