Year Founded:

PCC's origin dates back to 1876, when the Reverend S. Morgan Smith founded the company utilizing the talents of native York County craftsmen to produce a newly patented hydraulic turbine. The York, Pennsylvania company bearing his name became world renowned in the hydraulic turbine energy market.

In 1956, S. Morgan Smith manufactured the Reactor Internals for the Shippingport Nuclear Power Station.  This facility was the first commercial central electric generating station in the United States to use Nuclear Energy.  The plant was dedicated on May 26, 1958 by President Dwight D. Eisenhower as part of the “Atoms for Peace” program. 

In 1959 Allis-Chalmers acquired the business and entered other energy markets, manufacturing both commercial and military nuclear power equipment.

In 1983 Precision Custom Components was formed as a privately held company and continues the traditions of workmanship and superior quality in the production of heavy precision metal fabrications.

Today PCC is recognized as a world class producer of energy related equipment for commercial and government markets.
