The basic raw material is sand casting sand mold manufacture and sand binder.
The most commonly used foundry sand is silica sand.

Silica sand cannot satisfy the requirement of high temperature performance, the use of zircon sand and chromite sand, corundum sand and other special sand. Made for the sand mould and core has a certain strength, when handling, type and pouring liquid metal, without deformation or damage to the general to add sand binder in foundry, will become a sand loose sand bonded together. Is the most widely used sand binder clay, also can be used in a variety of drying oil or semidrying oil, water soluble silicate and phosphate and a variety of synthetic resin as a sand binder.

Used in sand casting sand mold by sand binder used in the outside of the green sand mold and build strength in different ways into clay, dry clay sand mould and chemical hardening sand mold.Clay bonded sand for casting, molding materials production is the process method has a long history, is also the most widely application scope. With a long history dating back to thousands of years ago; Its application scope, can be said that there is no place not all over the world.
