• Custom tube fabricator will invest nearly $4 million in Rhea County manufacturing facility
  • Company will relocate operations from California
  • Project will create more than 70 new jobs over three years

NASHVILLE, Tenn. – Tennessee Gov. Bill Lee, Department of Economic and Community Development Commissioner Bob Rolfe and Master Manufacturing Group (MMG) officials announced today that the company will relocate its headquarters and manufacturing operations from Rancho Cordova, Calif. to Dayton, Tenn.

The project represents the creation of 72 new jobs over the next three years.

MMG will invest $3.9 million to renovate and upgrade an existing manufacturing facility located at 220 Masters Way in Dayton. The building will also undergo extensive retrofitting in order to install holding tanks, electrical and hydraulic infrastructure, and create adequate ventilation for welding and painting operations.

MMG utilizes multiple manufacturing processes including CNC machining, mandrel bending and forming. Processes such as robotic, semi-robotic, manual welding as well as high pressure and high purity welding will be performed in-house at the Dayton facility.

Founded in 1956, Master Manufacturing Group, formerly known as Woodmack Products, Inc., provides custom tube and pipe manufacturing services, specializing in the gas appliance industry. The company offers aluminum, stainless steel and steel tubing components in various shapes, sizes and forms.

Since 2015, TNECD has supported 90 economic development projects in Southeast Tennessee, resulting in more than 12,500 job commitments and approximately $3.8 billion in capital investment.

This project will have a sizable impact on Rhea County, one of Tennessee’s at-risk counties, in the years ahead.” – TNECD Commissioner Bob Rolfe
