This new developed specific Foundry Sand is produced from the special selected high quality refractory raw material at very high temperature at 2,300 – 2,500℃. Our these ACFS sand has excellent solid cores with high strength and very low resin addition rates. The materials has excellent crystalline with formula is 5Al2O3-SiO2.

Application：

Shell moulds and cores for casting gray, Malleable and nodular cast iron, alloyed steel and carbon steel, non-ferrous metals, etc.

The Main Advantage

* Stabe quality on the chemical composition

* Perfect grain round shape and various grain sizes

* High gas permeability

* High temperature resistance

* Good break down and fast curing and good release
