Introduction
Sand casting refers to a casting method for producing castings in a sand mold. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting.
Advantage of Sand Casting
Sand casting is one of the casting processes, and the mold used for sand casting is generally composed of an outer sand type and a core. Because the molding materials used in sand casting are cheap and easy to obtain, the castings are easy to manufacture, and can be adapted to the single-piece production, batch production and mass production of castings. For a long time, it has been the basic process in casting production. At present, internationally, in all casting production, 60 to 70% of castings are produced in sand, and about 70% of them are produced using clay sand.
The main reason is that sand casting has lower cost, simple production process and shorter production cycle than other casting methods. Therefore, castings such as the engine cylinder block, cylinder head and crankshaft of the automobile are produced by the clay wet sand molding process. When the wet type does not meet the requirements, consider using a clay sand table dry sand type, dry sand type or other sand type. Clay wet sand castings can weigh from a few kilograms up to tens of kilograms, while clay dry castings can weigh up to tens of tons. Because sand casting has the above advantages, it is more and more widely used in the foundry industry. In the future, it will play an increasingly important role in the foundry industry.
