The Cly-Del Manufacturing Company is a mid-sized, family-owned manufacturer based in Waterbury, Connecticut. Founded in 1939 and now operated by the fourth generation, it concentrates on progressive stamping and deep-drawn metal components, a legacy that includes supplying metal parts to meet U.S. defense needs during World War II. The company emphasizes maintaining traditional American manufacturing practices while applying modern, precision-based production methods. Today, Cly-Del serves as a global supplier of battery cans and related components, and it maintains contract production of ammunition components, eyelet-type parts, shells, ferrules, cans, and other stamped or drawn parts. Its Waterbury facility has grown to about 200,000 square feet and houses more than 250 production presses, enabling high-volume output of billions of parts annually. In October 2023, the company expanded through the acquisition of Semcoeyelets.
