High Pressure Forged Fittings

PW Forging Group

Partnering with management to grow leading niche manufacturer of forged fittings, flanges and related products

PW Forging Group is a fully integrated manufacturer of high pressure forged fittings, flanges and branch connections that are sold into downstream oil & gas, petrochemical, LNG, industrial and shipbuilding end markets under the Penn Machine and Western Forge & Flange brands. Founded in 1931 and 1944, respectively, both Penn and Western have established themselves as industry leaders for quick lead times, comprehensive manufacturing capabilities and high-quality products. With a forging facility in Swedesboro, NJ, two machine shops in Aston, PA and Houston, TX and an integrated forging and machining operation in Cleveland, TX, PW Forging Group is well positioned to meet the dynamic needs of its customers.


Wynnchurch invested in Pennsylvania Machine Works in January 2020 and Western Forge & Flange in March 2020.


PW Forging Group represented an opportunity to acquire two well-positioned manufacturers with a differentiated business model serving attractive end markets.


Wynnchurch and management are driving both organic and inorganic growth by expanding into new products to provide a more comprehensive, value-added portfolio to its customer base.
