Sand casting is one kind of casting process. The casting mould for sand casting is made up of outer sand and core sand. Because the mold material is cheap and easy to obtain for sand casting , the casting mold is simple to manufacture and adapt the castings for single-piece production,batch production and mass production.So,it is the basic process in the casting production.At present, all kinds of castings’ production in the international,60-70% castings are produced by sand mold.
Crusher wear-resistant parts sand casting in domestic is very common, like jaw plate steel casting, high chromium plate hammer casting, crushing wall casting, concave steel casting and so on.As the large high wear-resistant castings in the crusher equipment,the accuracy is not very high, especially for the jaw plate high manganese steel casting that final castings don’t need lathe grinding.only some parts of crushing wall casting,convave high manganese steel casting, and roller leather casting need lathe grinding, so it is particularly suitable for sand casting.Because the jaw plate high manganese steel casting,high chromium plate hammer casting,convave high manganese steel casting etc for crusher wear-resistant castings are more wear-resistant than other casting process.
Compared with other casting methods, sand casting is low cost, simple production process and short production cycle. So, such as automobile engine, cylinder block, cylinder head, crankshaft and other castings are cast by sand casting.The weigh by sand casting can be from a few kilograms to dozens 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 a more and more important role in the foundry industry.
