Machining in Ringgold since 1977

Interstate Machine Works opened in Ringgold, Georgia in 1977 and operates today as a division of United Manufacturing Industries, Inc.

The shop does contract work for OEMs and industrial buyers: CNC and manual machining, welding, fabrication, laser cutting, brake press forming, automatic band saw cutting and sub-assembly. Heat treating, painting, zinc plating and ceramic coating are offered as well.

A job starts with a phone call about the parts. Drawings follow by email, the quote comes from there, and the parts are made and delivered just in time. Parts run from 1 oz. to over 200 lbs. and orders from one-off prototypes to production runs of thousands per year.

Who we work with

Some of our OEM customer relationships go back nearly 50 years. The work spans the truck, trailer, wrecker, valve, fire hydrant, construction, marine, military, off-road vehicle, communications and hardware industries.

Customers range from small shops to large NYSE companies. Some require a single part; others place repeat orders year after year. Either way the work is commercial and industrial only: parts and assemblies made to the customer's prints.
