Duncan Industries, Inc.

AN AEROSPACE MANUFACTURING

Duncan Industries has an 80-year history of providing precision parts to the aerospace industry. Tom Duncan founded this company in 1944, with his brother Lane Duncan, in order to meet the demands of the early aerospace industry and military needs in a post-World War II landscape. Tom was a visionary, and quickly understood the importance of the then developing rotorcraft. He set the foundation on which we rely to this day; blending workmanship, skill and incorporating the best available machinery and tools in order to produce high-quality, precision ground aerospace parts.

Todays’ manufacturing looks very different: technology is a key factor in our process, and it is necessary to continually adapt to improved manufacturing methods. At the same time, it is our skilled people that make Duncan Industries the premier supplier of precision parts to our customers.

To be the most reliable source of flight hardware in the industry.

Our Mission:
At Duncan Industries, we pledge to provide distinctive quality and unparalleled customer service as we strive to maintain the respect and trust of our clients, suppliers, and partner vendors.
