History
Originally founded in 1883 in Worcester, MA, the Wyman-Gordon Company boasts more than 125 years of forging experience and first manufactured forgings for the aerospace industry during WWI.
Recognizing the need for more expansive heavy manufacturing capabilities to support larger and more advanced aircraft designs, the Department of Defense built the forging facility now located in North Grafton, MA in 1946, equipping it initially with an 18,000 ton closed-die press.
In 1953, the facility was expanded to include the 35,000 and 50,000 ton presses in what was referred to as the “Air Force Heavy Press Program”. From this program’s inception, Wyman-Gordon was chosen to operate the North Grafton facility due to the company’s long-term experience and reputation in the industry.
In 1988, Wyman-Gordon purchased the facility outright from the U.S. Government and ran it as a private company until 1999 when Wyman-Gordon was acquired by Precision Castparts Corp. (PCC).

Modern design and simulation capabilities compatible with OEMs.
Wyman-Gordon provides full engineering services from collaborative concept development for developmental programs, to full design, modeling and simulation of production-ready forging products. 3-dimensional design of forgings and associated tooling uses CATIA V4/5. Proposed processes are simulated and refined with FEA (Finite Element Analysis) modeling techniques, and tool stress is analyzed and corrected prior to manufacture.
