Sand Casting Introduction

Sand casting – casting method for producing castings in sand molds. Steel, iron and most ferrous alloy castings can be obtained by sand casting. As the molding material used in sand casting is inexpensive and easy to be manufactured, the mold is simple to manufacture and can be adapted to the single piece production, mass production and mass production of castings, and has long been the basic process in foundry production.

Sand casting is a casting process in the sand casting mold used by the general sand and core type combination. As the molding material used in sand casting is inexpensive and easy to be manufactured, the mold is simple to manufacture and can be adapted to the single piece production, mass production and mass production of castings, and has long been the basic process in foundry production. At present, the international, in all casting production, 60 ~ 70% of the casting is produced by sand, and about 70% of which is produced using clay sand.

Sand casting advantage: Sand casting compared with other casting method of low cost, simple production process, short production cycle. So as the car’s engine cylinder block, cylinder head, crankshaft and other castings are used wet clay sand production process. When the wet type can not meet the requirements to consider the use of clay sand table dry sand, dry sand or other sand. Clay wet sand casting casting weight from a few kilograms up to tens of kilograms, and dry clay production castings can weigh tens of tons. Because sand casting has the above advantages, therefore, its application in the foundry industry more and more widely. Looking for future, it will be in the foundry industry plays an increasingly important role.
