Established in 1980 by experienced engineers and business people, TEC is, and always has been, uniquely qualified to serve the high technology and engineering markets.

TEC founder and CEO Gary Rupert began his career as an engineer with the Space Physics Research Laboratory at the University of Michigan, where he was responsible for major atmospheric research programs involving the Apollo, Fire, Surveyor, and X-15. As a founder of Raycon Corporation, Mr. Rupert revolutionized the Electronic Discharge Machining field. Both the automotive and aerospace industries owe their advances in diesel fuel injection and cooling systems to Raycon’s pioneering applications in precision hole production. In 1994, Michigan Governor John Engler appointed Mr. Rupert to the State Personnel Agency Board. Mr. Rupert holds a degree in electrical engineering from The University of Michigan, is the holder of several patented inventions, and has authored numerous technical papers.

Soon after beginning his career as a design engineer, TEC founder Bob Johnson was appointed to the team working on the Apollo XI Passive Seismic Experiment, more commonly known as the Moonquake Detector project. Mr. Johnson continued to work on moon exploration projects until 1974 when he was asked to join Raycon Corporation. As Engineering Manager, Mr. Johnson led the design and tooling of specialized state-of-the-art EDM machines that became pacesetters in the automotive and aerospace industries. As the original President of TEC, Mr. Johnson was a major force in establishing the business.
