Foundry Products Operations (Cincinnati Milling Machine) - The New Foundry

The New Foundry

The New Foundry opened and poured its first heat by December 1940, about a year before the Attack on Pearl Harbor. With the opening of the New Foundry the old Modern Foundry was torn down, and in its place additional machining and assembly space was created allowing a sevenfold increase in production during World War II. The Modern Foundry poured its last heat in 1941.

The Metal Fabricating Division foundry, as it came to be called, supplied all the needs of the Cincinnati Milling Machine Company and its successor, Milacron, Inc. At least three buildings were constructed of over 300,000 square feet (28,000 m2).

By 1942 the Cincinnati Milling Machine Company Foundry (CMM Co. Foundry) was producing 35,000 tons of castings with 32,000 tons being purchased from other sources. Melting in the New Foundry was done by up to four cupola furnaces. Production in the foundry was around the clock, seven days a week. Additional castings were needed, and the ‘Mill’ turned to outside Cincinnati local foundries. 27 outside foundries were also supplying castings to the Mill.
