Code 3085 applies to employers engaged in foundry operations of non-ferrous metal castings such as aluminum, brass, bronze, copper, silver and other non-ferrous metals for outside customers.

Also included under this classification are wood and metal pattern making, the pouring of molten metal into molds, and core and mold making of non-ferrous metals in furnaces.  When the castings are cooled, they are then machined to remove any imperfections.
