Hình dạng quả cầu cát Ceramcast để đúc cát

Mô tả ngắn:

Ceramcast is an special artificial ball sand for foundry industry, the sand mainly used to substitute for Japanese Cerabeads sand, fused ceramic sand, Ceramcast-black, chromite sand, zircon sand and silica sand. It has higher refractoriness, little thermal expansion, lower powder bulk density, excellent fluidity and filling, good spherical shape, higher reclamation rate to reduce casting companies production cost, lower the sand foundry defects, improving the quality of castings.

Lợi thế

● 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.

Ứng dụng

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.
