Category: Investment Casting

Investment casting is used to produce parts with complex geometries and tight tolerances. Alumina is used in the shell building process to provide strength, creep resistance, and thermal management during casting. Regulating heat transfer is critical in the solidification process and facilitates metals’ casting with different grain structures.

Alumina is used in investment casting depending on the melting temperature, solidification behavior, and desired grain structure of the metal. The most common metals cast in alumina-containing molds are vacuum cast superalloys and Titanium alloys, typically used in commercial aerospace, defense, and industrial gas turbine applications.

Sicheng ground products for flour have a broad distribution to allow for higher solids loadings and consistent plate weights. The reduced alkali content of our low and ultra-low soda flours improves slurry stability and lifetime.

Sicheng stucco products have the benefit of consistent distribution and minimal fines to prevent dusting during shell application. Reduced dust improves stucco adherence to the dip coat and also provides a safer and cleaner operating environment.
