3. Ceramic Foundry Sand General advantages
Solid sphere: The shape of Ceramsite is spherical with smooth surface and less surface area and offering a very good flowability and filling ability. To compare with other sands else, less binder is used at the same mold strength and higher venting ability. It also offers the excellent collapsibility.
Lower thermal expansion rate: It makes the dimensions of castings better, less crack and defect and higher output.
Lower breakage rate: Ceramsite has a higher density and a very lower breakage rate at the reclaimation. It makes a better reclamations rate to reduce the waste sand and the pollution.
4. Ceramic Foundry Sand Particle Size Distribution
The particle size distribution can be custom-made according to any customer’s specific requirement.
