Kaist Sintered Ceramic Sand is a premium, high-performance foundry medium specifically engineered for the production of high-precision molds and cores. Composed of high-purity mullite crystals, this artificial sand is produced through a controlled firing process of spherical granules rather than crushing, ensuring exceptional quality stability and uniformity. It is an ideal raw material for cutting-edge sand 3D printing technologies, compatible with leading systems such as ExOne, Voxeljet, and KOCEL.
Designed for high-value casting in the automotive, oil & gas, mining, and construction industries, Kaist Ceramic Sand is essential for manufacturing complex components like cylinder blocks, hydraulic valves, pumps, and impellers. By providing superior heat resistance and a smoother surface finish, it enables foundries to achieve tighter tolerances and higher resolution in their final metal parts, regardless of whether they use traditional mold-making or advanced additive manufacturing.
