Product details

"Shengshi Weiye" brand ceramic foundry sand is made from high quality bauxite through calcination, electrofusion, granulation,sieving and other processes.

● Product Characteristics

1.The ceramic foundry sand is spherical with good fluidity, filling performance and air permeability.

2.The ceramic foundry sand is a neutral material, both acid and alkali binders can be used.

3.The ceramic foundry sand is cost-effective and it has very good recycling performance.

4.The ceramic foundry sand has very smooth surface and compact structure, the binder can be evenly covered, and the addition amount is reduced by 30%-50%.

5.The ceramic foundry sand’s thermal expansion coefficient is small, the performance can be comparable with zircon sand, with it to prepare core sand, castings will not produce expansion defects.

6.The ceramic foundry sand has high refractoriness and easy to collapse.

7.The ceramic foundry sand has high thermal conductivity and good stability and it is not easy to crack.
