Company History & Overview

Oak Ridge Tool & Die was founded in 1962 by Ben Mullins, Jay Cotter and Don Wilkin as a two-room machine shop. In 1967 Ben Mullins and Jay Cotter moved the company to a new 12,000 square foot facility in the Industrial Park of Oak 

Ridge and changed the corporate name to Oak Ridge Tool-Engineering, Inc. (ORT-E). After Mr. Cotter’s untimely death in 1970, Ben Mullins continued the business until his sons joined; Terry, in 1973 and Steve, in 1977. The addition of key management personnel has enabled ORT-E to expand to a facility that is over 100,000 square feet. 

Our core business is providing engineering and manufacturing services for custom tooling, components, and mechanical equipment. We have the privilege of serving the Aerospace, Defense,Medical, Architectural and Energy-related companies throughout the Nation and the World. Some programs we support include the Delta IV, TADS Apache, International Space Station, MEV Cyclotron, Spallation Neutron Source, High Flux Isotope Reactor, Gas Centrifuge and Decontamination of former DOE Nuclear Weapons Facilities.

In the fall of 2005 ORT-E upgraded to a new 104,000 square foot facility on 42.5 acres in Oak Ridge’s prestigious Commerce Park. We have Administrative and Engineering Offices, Machining, Fabrication, Receiving/Storage, Assembly/Test, and Inspection. At this new location, the environment in all areas is controlled for precise manufacturing, measurement and verification.
