Precision-engineered sands that meet the extreme accuracy and high-temperature demands of aerospace manufacturing

At TUSHUN, we provide aerospace-grade ceramic sands engineered for the production of high-performance components. In an industry where tolerances are measured in microns and material integrity is critical, our products offer unmatched thermal stability, low thermal expansion, and exceptional strength. These properties reduce dimensional errors and surface defects during casting, ensuring components meet stringent aerospace standards. From turbine blades to structural parts, our sands support complex geometries and maintain integrity under extreme operating conditions. With our solutions, aerospace manufacturers can achieve the highest levels of reliability, safety, and efficiency.

Case

Fused Ceramsite Sand (Baozhu Sand)

Posted on 2025-09-29

+

(1)Applicable Castings:

-Stainless steel and alloy steel housings

-Brackets, non-load-bearing supports

(2)Processes: Resin-bonded sand,；V-process,；lost foam

 

(3)Why It Works:

Refractoriness up to 1850°C, suitable for steel and alloy steel castings

Low thermal expansion (0.13% @1000°C), ensures dimensional accuracy

High reusability (up to 98%), lowers cost for repeat production
