Wynnchurch Capital acquired Pennsylvania Machine Works (Penn Machine), a fully integrated manufacturer of high-pressure forged fittings and branch connections. Headquartered in Aston, Pa., Penn Machine produces high-quality products in a diverse variety of material grades that are sold into the downstream oil and gas, petrochemical, industrial and shipbuilding end markets. The company is supported by its forging facility in Swedesboro, N.J., and two machine shops in Aston and Houston, Texas.

Rosemont, Ill.-based Wynnchurch Capital also recently acquired two closed-die forging facilities of Allegheny Technologies that produce high-value, complex forgings for OEMs.
