Gemcor’s robust, all-electric fastening line provides airframe manufacturers with a cleaner, faster, more precise and reliable system.

Founded in 1937 by Thomas Speller Sr., Gemcor invented the automated fastening process to support aircraft production during WWII. More than 2200 Gemcor systems have been shipped since Gemcor’s Drivmatic® process quickly became an industry standard for automated aircraft assembly.

In 2016, Gemcor joined Ascent Aerospace, which integrates factory automation with aircraft tooling expertise, to provide turnkey solutions from one, vertically-integrated organization. Ascent’s businesses, each an industry leader in its own right, combine experience, design capabilities and program management skills, and cover the full spectrum of assembly technology. Whatever the need or application, we provide affordable, right-sized solutions.
