Leading the world in unmanned systems centered on pipe benders! !
We have been manufacturing pipe benders (pipe bending machines) consistently for more than 70 years. It was the first manufacturer in Japan to produce a double-bending pipe bender, followed by an NC double-bend pipe bender that was the first to be sent to market. In addition, we have responded to user needs by quickly bringing IT technology into peripheral devices for pipe bending technology. We are constantly working on technological development ahead of the generation, and we have received wide support from the industrial world.
Currently, it is known as the only bender manufacturer with unique technology (patent, domestic, and overseas) and numerous achievements in "unmanned system" and "multi-process pipe bender" that incorporate multiple processing processes into the front and rear processes of pipe benders.
We have received high evaluations not only in Japan but also overseas, and we will continue to challenge technological development with the motto of being a company that contributes widely to society with an eye to users and the future by accumulating know-how cultivated from many years of experience.
