Frequently Asked Questions
Ceramic sand offers higher refractoriness (≥1800°C), better fluidity due to its spherical shape, and a significantly higher recovery rate (98%), which reduces both waste and production costs.
The spherical shape improves the flowability and filling efficiency of the sand around the foam pattern, leading to higher gas permeability and a lower defect rate in the final casting.
Yes, we provide customized particle size distributions ranging from 45μm to 2000μm to ensure the sand meets the exact requirements of your specific molding process.
Due to the absence of binders and high recovery rates, the sand consumption typically ranges between 1.0 to 1.5kg per ton of castings.
Our ceramic sand has lower thermal expansion and thermal conductivity, which minimizes mold deformation during the pouring process, resulting in more precise dimensions.
Absolutely. With an annual production capacity of 200,000 MT, we are equipped to provide a fast and stable supply to foundries worldwide.
