Company History

Since its founding in 1958, JTEKT Thermo Systems has a history of providing manufacturing equipment that focuses on heat treatment technology all over the world. Starting with an industrial furnace, it has ventured out into the semiconductor industry where technological innovation is progressing at a rapid pace. In addition to our lineup of equipment for experimentation and electronics, we have also developed the Moldatherm Heater type. From there on we have expanded to enter the FPD industry by combining these technologies and have grown into a heat treatment equipment manufacturer engaged in a wide range of industries. We celebrated our 50th anniversary in 2017 and are continuing development.
