Ceramic Foundry Sand Property From above table, Ceramic Foundry Sand has the following characteristics: The thermal expansion coefficient of ceramic sand is very low, which is similar to zircon sand. Using the Ceramic Foundry Sand to make moulds and cores, the veins and other expansion defects of castings are eliminated Because of the great spherical

Pue to its unique physical and chemical properties,the sand has the following charateristics and adcantages: Prevention of sand expansion defects,especially finning/veining Elimination of gas-forming additives Prevention of reactions between metal and moulding sand Prevention of metal penetration Reduction of core weight Improved flowability of moulding sand Influence on the formation of microstructure Pouring of thin-walled

Ceramic Foundry sand ,also called as Fused Ceramic Sand is made from high quality bauxite, by re-fused and blown to ball type. With advantage of fine surface smooth finish and air permeability, it is a new type casting material for precision casting, coated sand and self hardening sand etc.At the present, Ceramsite is acknowledged in the

Ceramic Foundry Sand, technically named as “Fused Ceramic Sand for Foundry”, also named as ceramsite, is good spherical grain shape which is made from calcined bauxite. Its main content is aluminum oxide, and it is processed by melting, blowing, sieving and blending. Ceramic sand, has much better properties than that of silica sand to gain

The thermal expansion coefficient of ceramic sand is very low, which is similar to zircon sand. Using the Ceramic Foundry Sand to make moulds and cores, the veins and other expansion defects of castings are eliminated Because of the great spherical shape of the particle, Ceramic Foundry Sand has good flowability and easy to fill

Resin Coated ceramic sand advantages: Higher refractoriness—-to cast metals with high pouring temperature (cast steel, alloyed cast steel, stainless steel, etc.) High strength and toughness—–to produce more complicated cores with thin sections. Lower thermal expansion—–to avoid expansion defects Higher reclamation yields—-to reduce waste sand disposal, to decline costs. Excellent flowability —–to make complicated cores. Lower
