Canton Drop Forge


The company was founded in 1903 and became a pioneer producer of forgings for the early automotive and aircraft industries.  Aircraft containing CDF forgings flew in both world wars and in the Korean and Vietnam conflicts.  Lindbergh's Spirit of St. Louis, the Golden Gate Bridge, the German Zeppelins of the pre-World War II period and a wide variety of early industrial and electric generating equipment incorporated CDF forgings, as did America's first aircraft jet engines.


The current plant was built by the government for WWII to make cylinder retainers for piston-engine aircraft and propeller hubs.  The founding family managed this plant and then purchased it from the government after the war.


The original plant was located near downtown Canton.  That plant made smaller parts in higher volume.  It was closed in 1984 when it could no longer compete with foreign forgers.


In 1981, Jim O'Sullivan and four other investors purchased CDF from the founding family.  Over the years, Mr. O'Sullivan purchased shares of the other stockholders and became the primary owner of CDF in 1997.


Forgings are used for critical industrial and aerospace applications that require materials with high strength and good toughness and durability.  Forgings have much more reliable strength-to-weight ratios than castings and are much tougher and resistant to impact types of failure.  The largest market for forgings made in North America is automotive, with roughly 60% of the total market followed by aerospace with about 25%.  CDF has no involvement in the automotive market where forgings are small, and made in high volume on automated production cells.


Customers select CDF because we produce competitively priced, high-quality, large forgings in small lots with on-time deliveries.
