Casting ceramic sand AFS30
Product introduction of Casting ceramic sand AFS30
Casting ceramic sand AFS30 is a medium fine foundry sand. It is made from fused aluminum oxide mineral bauxite ore. So the refractory performance is excellent. It can resistant high temperatures of casting steel and casting iron. Meantime, the unique ceramic ball appearance makes the ceramic sand to fill the mold easier. It also has low angularity and a low thermal expansion rate. Casting ceramic sand can improve the casting quality of the inner density and outer surface.

- Good flowability and low angularity coefficient.
- Proper particle size distribution for most casting technologies.
- Low humidity.
- Low thermal expansion rate.
- Good thermal conductivity and good air permeability.
- High bending strength and press strength.

FAQ:
Q: Are you a manufacturer?
A: Yes, Our factory was founded in 1999. We are an experienced manufacturer of foundry ceramic sand.
Q: What are the key quality indexes of casting ceramic sand?
A: First of all, the Al2O3 content. We have three grade:75% Al2O3 ceramic sand,73% Al2O3 ceramic sand,70 Al2O3 ceramic sand.
Secondly, the particle size distribution of ceramic sand. We will provide samples according to the customer’s requirements. And make the same particle percentage coincide with confirmed sand.
Q: Where is the nearest port from your factory?
A: Qingdao and Tianjin are both near to us.
Q: What is the HS code of ceramsite sand?
A: Since there is no specific HS code for ceramic sand, there are HS codes 69149000 and 68159990 suitable for exporting casting ceramic sand. But with our experience, HS code 68159990 is easier to do custom clearance with no risk of being inspected.
Q: How do you operate the QC system?
A: Before shipment, we will take 1 day to check the chemical composition for every bag. Our QC staff will take another day to check particle size distribution for every bag. We will reserve samples from each batch production in case there is anything wrong.
Q: What is the lead time for each order?
A: It depends on the quantity and sand size required. Generally 5-10 days for FCL（20-25MT）.
