Short Description
Ceramic foundry sand is a synthetic sand characterized by its high refractoriness, reaching up to 1800°C. Widely applied in the foundry industry as molding and core sand, its near-perfect spherical shape enables excellent flow and gas permeability. This shape allows for a binder reduction of up to 50% in core production compared to other sands, while still maintaining core strength. Additionally, using ceramic sand for casting results in an outstanding surface finish, enhancing the quality and precision of the final cast products.

Features of Ceramic Foundry Sand
Uniform Composition
Ensures reliable and consistent casting results, as each grain maintains a stable chemical structure, enhancing overall performance during casting and reducing variability across applications.
Stable Grain Size and Air Permeability
Ceramic Foundry Sand’s consistent particle distribution promotes excellent air flow, reducing casting defects. Its stable grain size and permeability lead to smoother casting processes and improved final product quality.
High Refractoriness
Withstands extreme temperatures up to 1800°C, making it ideal for high-temperature applications without compromising integrity, ensuring durability and reliability in demanding casting environments.
Resistance to Wear and Thermal Shock
Ceramic Foundry Sand is engineered for superior durability, withstanding wear, crushing forces, and sudden temperature changes. This high resistance prolongs its lifespan, reducing replacement needs.
Low Thermal Expansion
Minimizes distortion during casting, allowing for precise results by reducing dimensional changes. This property helps in maintaining the accuracy of molds under high temperatures.
Enhanced Fluidity and Filling Efficiency
The spherical shape of Ceramic Foundry Sand enhances flow and mold filling efficiency, resulting in a smoother casting surface. This property reduces the need for finishing work, boosting production efficiency.
High Reclamation Rate
Maximizes reusability in sand loop systems, reducing waste and lowering material costs. This high reclamation rate supports sustainable practices in casting operations by extending sand usability.
