02 12月 Filter casting Factory
Filter Casting Factory uses an aqueous slurry through which a ceramic foam material is passed to impregnate a foam precursor made of a flexible open-cell polymer strut. The subsequent drying and firing of the material produces the final ceramic foam product.
In order to manufacture aluminum products with acceptable characteristics, such as beverage cans and aircraft fuselage parts, the aluminum must be substantially free of inclusions and defects. When aluminum melts at the beginning of the casting process, it becomes full of oxides, borides, salts, and other impurities, which may eventually appear as harmful inclusions in the final product. It is desirable to remove these inclusions before curing the aluminum. This is usually done by passing molten aluminum through a ceramic foam filter.
