"Ishibashi Seisakusho", which was founded in 1932 and designs and manufactures various gear devices (gear boxes) such as reduction gears and speed increasers. Since our establishment as a forging factory in 1932, we have always tried new things. Currently, based on the design and manufacture of gear devices such as speed reducers or speed increasers, it boasts the top track record in Japan for speed increase machines for medium to large wind turbines, as well as for resin machines and twin-screw extruders. We are advancing business development specializing in more advanced gear devices such as high-speed gear devices. In addition, we have been working on dealings with overseas and building cooperative relationships from early on, laying the foundation for today's business. In 1989, the name was changed to "Frender Ishibashi Seisakusho Co., Ltd." through a joint venture with Friender (Germany), and as a member of the Friender Group, accumulated technical know-how through various exchanges for 12 years. With the dissolution of the capital tie-up in 2001, we made a new start as "Ishibashi Seisakusho Co., Ltd.", and in 2010 we established an assembly factory in China and a service factory in the United States and started operation. Although it is a small company with about 130 people, Optimums Solution & Mobility (optimal design) always aims at the world, explores what is truly required value on the world stage, and thinks about "what can be done because it is small". And mobility) is the greatest feature of our company, and we will continue to work to maintain and develop it.
