- Product Name: Ceramic Sand for Precision Casting
Shell casting process Molten ceramic sand (ceramic sand) is used in shell mold precision casting process. It is suitable for small and medium-sized castings of different materials such as cast iron, cast steel, medium and low alloy steel, stainless steel and non-ferrous alloys. Molten ceramic sand (ceramic sand) with particle size of 40/70, 100,70/140 can be used.

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 (ceramic sand)
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.
Application of Molten Ceramic Sand in Shell Casting
Molten ceramic sand (ceramic sand) shell mold precision casting process, casting size accuracy can reach CT7 ~ CT6 level, surface roughness of Ra12.5 or more. Can greatly improve the quality of sand casting castings, and can partially replace the lost wax precision casting process; the use of ceramic sand shell precision casting process can greatly improve the production efficiency and market response speed; the use of ceramic sand shell precision casting process can significantly reduce the cost of castings and achieve huge economic benefits; ceramic sand shell precision casting process, old sand regeneration is simple and convenient, greatly reducing the emission of solid waste and other pollutants, while obtaining economic benefits, it has obvious environmental benefits and is a sustainable casting technology.
