Frequently Asked Questions
Kaist SuperSand offers a significantly higher recycling rate (up to 98%) and is more cost-effective, producing 25% more sand cores per unit of weight due to its optimized bulk density.
Yes, Kaist SuperSand is a neutral material, making it fully applicable and compatible with both acid and alkali resins.
Its extreme refractoriness (≥1800℃) prevents sand burn-on and sintering, while its low thermal expansion coefficient ensures high dimensional accuracy.
Absolutely. We provide a wide range of particle size distributions (from 45μm to 2000μm) that can be customized according to your specific foundry requirements.
It promotes "green casting" by maximizing the reclamation rate, which drastically reduces the volume of industrial solid waste discharged by the enterprise.
A lower angular coefficient (≤1.1) means the grains are more spherical, which effectively improves the breathability and surface accuracy of the cast products.
