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 worldwide as the newest and the best ideal sand for the foundries and has a very wide feasibility of applications for the future development.
Application and how to choose available size:
1. Shell molding
2. Precision Casting
3. Lost foam casting
4. Heavy steel casting
5. Resin coated sand casting
6. Vacuum casting
7. Investment casting
