- Product Name: Coated Ceramic Sand
Coated sand Casting sand Molten ceramic sand (Ceramic Sand) is used in the casting process of coated sand, which has the advantages of fast speed, high efficiency, high precision and high smoothness, and is suitable for the manufacture of castings with higher precision. Can be used 40/70,50/100,70/140 particle size of molten ceramic sand (Ceramic Sand).

Molten ceramic sand (ceramic sand) commonly used particle size:
8/12, 12/20, 30, 20/40, 30/50, 40/70, 100, 140, 140/200, etc.
Characteristics of fused ceramic sand (eramic xand)
1. The thermal expansion rate is small-the expansion rate of molten ceramic sand (Ceramic Sand) after heating is 1/5 of silica sand and 1/2 of chromite sand. The castings produced have high dimensional accuracy, few veins and crack defects, and high casting yield;
2, The sand is spherical, the surface is smooth, so that the binder can be evenly covered and less consumption, sand liquidity is good, easy to spring, and good air permeability;
3, Is a neutral material-acid, alkali binder can be used;
4, High fire resistance-reduce the tendency of casting sand;
5. Good crushing resistance-Ceramic Sand is dense in material, high in compressive strength, low in crushing rate during repeated use, which reduces waste sand emissions and is conducive to environmental protection;
6, Cost-effective-compared with zircon sand, its price is only 20 to 40% of zircon sand. At the same time, because the sand is spherical, its surface area is small, the amount of binder can be reduced by 30% to 50%;
7. Wide range of applications-water glass sand, resin sand, precision casting, 3D printing, polishing and cleaning of copper and aluminum parts, etc.
