1. Product Overview
Shiyan Technology’s Ceramic Foundry Sand (also known as Ceramsite) is a high-performance, spherical artificial sand used in foundry industries. Made from high-quality bauxite and processed through electric arc furnace melting and spray granulation, our ceramic sand offers superior refractoriness and structural stability compared to traditional silica or chromite sand.
- Manufacturing Experience: 20+ Years
- Factory Scale: 5,000 sqm Production Facility
- Global Compliance: Meets FEPA, JIS, AFS, and GB Standards
2. Key Advantages for B2B Buyers
- Perfect Spherical Shape: High flowability and excellent gas permeability, reducing resin consumption by up to 30-50%.
- Ultra-High Refractoriness: Melting point ≥2050∘C, ideal for heavy steel and alloy casting.
- Extremely Low Thermal Expansion: Significantly reduces casting defects such as veining and sand expansion.
- Superior Durability: High crush strength ensures low breakage rate during reclamation, allowing for 10-20 times reuse.
