● Uniform component composition
● Higher refractoriness≥1800℃. In special casting conditions with higher temperature, it can provide better adaptability and lower the ratio of defects such as sand burning-on, sintering, and veining;
● Low thermal expansion coefficient. It can greatly lower the defects and improve the size accuracy of cast products.
● Lower angular coefficient<1.1. Ceramcast ball shape can effectively improve the breathability and surface accuracy of cast products.
● Lower bulk density(1.45-1.6g/cm3). Ceramcast bulk density is similar with silica sand’s, If the weights are the same, KAIST ceramic sand can produce additional 25% sand core compared with fused ceramic sand to lower the procurement cost.
● The stable product properties and uniform colors can guarantee high quality supply.
● a neutral material, KAIST ceramic sand is applicable to acid and alkali resins.
● Higher renewable recycling characteristics. The recycling rate can reach 98%, it can reduce your purchase cost, and reduce the enterprise solid waste discharge to the maximum extent, keep the workshops are dust-free, green, and environment-friendly.
Ceramcast can be used for all types of sand castings, now we have successfully applicated to Resin-coated sand, Cold box sand, green sand, 3D sand printing, lost foam casting, No-baked sand, etc, steel castings, iron castings, alloy castings, aluminum casting, copper castings, etc. high-end sand casting. Kaist Ceramcast have excellent reclamation property, it can be used in mechanical and thermal reclamation ways, lower waste sand discharge, offer you a green foundry factory.
The particle size distribution can be customized according your requirement.
