Official definition
This U.S. industry comprises establishments primarily engaged in pouring molten nonferrous metals (except aluminum) into molds to manufacture nonferrous castings (except nonferrous die-castings and aluminum castings).

Which code does this activity belong in?
NAICS 331529 covers establishments that pour molten nonferrous metals (excluding aluminum) into molds to produce castings through gravity casting methods. The key distinction from Nonferrous Metal Die-Casting Foundries is the casting process: 331529 uses pouring into molds, while die-casting involves introducing metal under high pressure into dies. Aluminum castings, regardless of production method, are classified in Aluminum Foundries (except Die-Casting), not this code, even when produced by similar gravity-pouring techniques.
