Abstract
334,714. Metal Castings, Ltd., and Nicholson, A. H. Sept. 12, 1929. Cores; core materials. - In casting a hollow body of aluminium alloy or other metal the core is made of zinc alloy or another metal such that it will not melt during casting but can be removed after casting by a heat treatment. The core metal preferably has the same co-efficient of expansion as the casting and may be reinforced by a less fusible insert where the metal entering the die strikes it. Castings, extracting.-The castings are reheated to run out the core metal, the inserts are removed, and adhering core metal is shaken or dissolved out.
