Founded in 1957 by three Rensselaer Polytechnic Institute researchers, Dynamic Systems Inc. builds Gleeble® thermo-mechanical physical simulation systems that reproduce the heat and mechanical forces materials experience during manufacturing and service. The Poestenkill company began by solving weld heat-affected-zone problems and has since developed systems used worldwide to study materials, validate processes, and guide production decisions. DSI also supports its equipment with factory-led training, contract testing, calibration, and upgrades.
