Ceramsite sand is a kind of fused ceramic sand,it is made from calcined bauxite with main content aluminium oxide processed by melting,blowing,sieving and blending.

Choosing the right size of ceramic sand for foundry applications depends on several factors, including the type of casting process, metal being poured, mold design, and surface finish requirements

the main application of Foundry Ceramic Fused Sand is as a high-performance molding aggregate in advanced and precision casting processes like Lost Foam, V-Process, 3D Sand Printing, and high-quality core making, where its superior thermal stability, spherical shape, and durability lead to higher casting quality, lower defect rates, and reduced overall production costs.

Using ceramic foundry sand as stuffing (or backing) sand is a advanced foundry practice where it forms the bulk of the mold behind a high-performance facing sand

Spherical Foundry Sand shows outstanding reusability and shakeout performance, with a high sand reclamation rate. It is non-toxic, low in free silica dust, environmentally friendly and able to improve the working environment of foundry workshops. It is widely used in shell molding, cold box process, furan resin sand and 3D printing sand casting processes, and has become a mainstream high-quality raw sand for high-end iron casting, steel casting and non-ferrous metal casting worldwide.

Ceramsite sand improves casting quality, reduces scrap rates, saves binder, simplifies cleaning, and lowers long-term production costs. It is one of the most cost-effective high-performance foundry sands available today.
