Ex-Cell-O

Ex-Cell-O Corporation was a diverse manufacturing company founded in Detroit, Michigan, in 1919. Originally known as the Exotic Metal Alloys Company, it specialized in producing hardened and precision-ground metal parts. The name was changed to Ex-Cell-O (a phonetic spelling suggesting "excellence") to reflect this emphasis on quality.

Over the decades, Ex-Cell-O expanded into various industries, most notably packaging equipment for the dairy and food industries, aerospace components, and machine tools. Its Pure-Pak packaging machinery became ubiquitous for milk and other liquids globally.

In the aerospace sector, Ex-Cell-O manufactured precision components for aircraft engines and other applications. Its machine tool division produced a range of metal-cutting equipment, including boring machines, milling machines, and grinders.

During World War II, Ex-Cell-O played a significant role in the war effort, producing vital components for military vehicles and aircraft.

By the late 20th century, Ex-Cell-O began to be dismantled through acquisitions and sales of its various divisions. Its packaging operations were eventually sold off to form part of the Tetra Pak group. The aerospace divisions were acquired by other companies within that industry. The machine tool operations were also sold.

Today, the original Ex-Cell-O Corporation no longer exists as a single entity, though the name may persist in some product lines or subsidiary companies acquired from the former corporation. Its legacy remains significant in the history of American manufacturing, particularly in the areas of packaging machinery and precision machining.
