Iron Foundries

This includes establishments primarily engaged in pouring molten pig iron or iron alloys into molds to manufacture castings (e.g., cast iron manhole covers, cast iron pipe, cast iron skillets). Establishments in this industry purchase iron made in other establishments.

Steel Investment Foundries

This includes establishments primarily engaged in manufacturing steel investment castings. Investment molds are formed by covering a wax shape with a refractory slurry. After the refractory slurry hardens, the wax is melted, leaving a seamless mold. Investment molds provide highly detailed, consistent castings. Establishments in this industry purchase steel made in other establishments.

Steel Foundries (except Investment)

This includes establishments primarily engaged in manufacturing steel castings (except steel investment castings). Establishments in this industry purchase steel made in other establishments.

Nonferrous Metal Die-Casting Foundries

This includes establishments primarily engaged in introducing molten nonferrous metal, under high pressure, into molds or dies to make nonferrous metal die-castings. Establishments in this industry purchase nonferrous metals made in other establishments.

Aluminum Foundries (except Die-Casting)

This includes establishments primarily engaged in pouring molten aluminum into molds to manufacture aluminum castings (except nonferrous die-castings). Establishments in this industry purchase aluminum made in other establishments.

Other Nonferrous Metal Foundries (except Die-Casting)

This includes establishments primarily engaged in pouring molten nonferrous metals (except aluminum) into molds to manufacture nonferrous castings (except nonferrous die-castings and aluminum castings). Establishments in this industry purchase nonferrous metals, such as copper, nickel, lead, and zinc, made in other establishments.

Iron and Steel Forging

This includes establishments primarily engaged in manufacturing iron and steel forgings from purchased iron and steel by hammering mill shapes. Establishments making iron and steel forgings and further manufacturing (e.g., machining, assembling) a specific manufactured product are classified in the industry of the finished product. Iron and steel forging establishments may perform surface finishing operations, such as cleaning and deburring, on the forgings they manufacture.

Nonferrous Forging

This includes establishments primarily engaged in manufacturing nonferrous forgings from purchased nonferrous metals by hammering mill shapes. Establishments making nonferrous forgings and further manufacturing (e.g., machining, assembling) a specific manufactured product are classified in the industry of the finished product. Nonferrous forging establishments may perform surface finishing operations, such as cleaning and deburring, on the forgings they manufacture.

Metal Crown, Closure, and Other Metal Stamping (except Automotive)

This includes establishments primarily engaged in (1) stamping metal crowns and closures, such as bottle caps and home canning lids and rings, and/or (2) manufacturing other unfinished metal stampings and spinning unfinished metal products (except automotive, cans, and coins). Establishments making metal stampings and metal spun products and further manufacturing (e.g., machining, assembling) a specific product are classified in the industry of the finished product. Metal stamping and metal spun products establishments may perform surface finishing operations, such as cleaning and deburring, on the products they manufacture.

Machine Shops

This category includes establishments known as machine shops primarily engaged in machining metal and plastic parts and parts of other composite materials on a job or order basis. Generally machine shop jobs are low volume using machine tools, such as lathes (including computer numerically controlled); automatic screw machines; and machines for boring, grinding, milling, and additive manufacturing.
