Ceramic cores for precision casting of superalloys

It can be used for precision casting of equiaxed, oriented and single crystal hollow parts. It has the advantages of high dimensional accuracy, high operating temperature, small thermal deformation at high temperature, good product strength that can meet the requirements of wax pressing and casting processes, and easy core removal.

Mainly used in the mass production of superalloy precision castings with complex inner cavity structure in aviation, aerospace, ship, chemical, energy and other industries.

Ceramic core for precision casting of titanium alloy


Ceramic cores for precision casting of titanium alloys have the advantages of high operating temperature, good thermochemical stability, and no reaction with molten titanium alloys.

It has been successfully used in the precision casting of various titanium alloy hollow parts, which can significantly improve the casting qualification rate of the castings.

Ceramic cores for precision casting of aluminum and magnesium alloys

The aluminum alloy precision casting ceramic core is made of water-soluble matrix material. The outstanding feature of this product is that the core removal is simple. After the casting is cast, it can be easily removed by placing it in water, and no special core removal equipment is required.

Therefore, the use cost of the product is low, and it is more suitable for mass production of aluminum alloy precision hollow parts.

Ceramic cores for stainless steel casting

The ceramic core for stainless steel precision casting should have the characteristics of high operating temperature, no reaction with metal under high temperature conditions, easy core removal, and low thermal cracking of hollow thin-walled castings.

Al-Si Crucible

The aluminum-silicon ceramic crucibles produced by the company are mainly used for investment casting of high temperature alloys. The crucibles can be used in the form of child and mother crucibles to ensure the safety of high-frequency induction furnaces. The child crucibles are used to carry alloys. Protective effect, do not need to be replaced frequently.

The crucible material is composed of high-quality alumina and fused silica. The crucible has excellent high-temperature performance and thermal stability, which ensures that the crucible will not crack or drop powder during the rapid heating and melting process of the superalloy. Smooth, free of defects such as cracks, slag, powder, impurities, etc., to ensure that the superalloy is not polluted when it is melted.
