NTMA / Arizona Chapter Celebrates 54 years in 2026!
The Arizona Chapter (ATMA) of the National Tooling & Machining Association (NTMA), is a trade association comprised of over 70 Regular and Industry Partner member companies located throughout the State of Arizona. Our chapter was formed in 1972 and is one of 37 state chapters.
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.
