About NTMA

The NTMA is the national representative of the custom precision manufacturing industry in the United States.

Many NTMA members are small businesses, privately owned and operated, yet the industry generates sales in excess of $40 billion a year. Our nearly 2000 members design and manufacture special tools, dies, jigs, fixtures, gages, special machines, and precision machined parts. Some firms specialize in experimental research and development work.

The tooling and machining industry is critical to our country's economic health as it makes possible the existence of virtually every other manufacturing industry. Tooling is, in its simplest sense, the means of production. "Special" tooling, such as dies and molds, is custom designed and made to manufacture specific products, generally in quantity, and to desired levels of uniformity, accuracy, interchangeability, and quality. Machining involves the use of a wide variety of machine tools to cut or form material, usually metal, to precise shapes and dimensions.

NTMA member companies use the full range of machine tools and related equipment, ranging from small automatic lathes for miniature parts, to enormous boring mills. The industry is probably the most technologically-advanced of all small manufacturing activities, and enjoys widespread deployment of computer-numerically-controlled (CNC) machines and other computer-aided design and manufacturing (CAD/CAM) techniques.

Our industry supplies the necessary precision tooling and machining for such vital industries as defense, automotive, aerospace, appliance, business machines, electronics, agricultural implements, ordnance, transportation, environmental, construction equipment, nuclear, and many more. In point of fact, nearly every manufacturer does business at one time or another with the contract tooling and machining industry.

NTMA members are organized into 49 local federated chapters and tool centers throughout the country. Chapters can be found in the Chapter Listing.
