Company History

In the 1950s, John W. Heaton was a mechanic working at the Owens Corning’s fiberglass facility in Anderson, South Carolina.  He spent most of his nights making replacement items for the company on a contracted basis. When Owens Corning announced its new facility in Aiken, South Carolina, John moved there and started a new machine shop, Precision Machine Works. During the 1960s, PMW grew in its core market, the fiberglass industry.  In the 1970s, John’s son, Charlie, joined the company with a vision of adding CNC machining capabilities. With this evolution, PMW expanded into new industries as a precision parts manufacturer. Third generation Ashley Heaton became Chairman and President in 2002, and by 2015, PMW was certified for both ISO9001 and AS9100. In 2019, following a highly successful project in the space industry, PMW established its current state-of-the-art facility in Liberty, SC to support customers in the Aerospace, Defense, and Medical Device industries.

In 2021, PMW Aero formed a strategic partnership with Banbury Private Capital to augment the leadership team and expand its network of trusted, value-adding industry partners.

PMW Aero is supported by an operationally focused management team of industry veterans.
