Feb. 5, 2013 - PRLog -- At the core of Ishibashi’s testing procedure is Brüel & Kjær’s PULSE analyzer and - following the acquisition of their first system in 1998 - the company now has four PULSE systems in Japan and an additional one in their Chinese facility.

Ishibashi accommodates requirements from customers such as Mitsubishi Heavy Industry, and focuses on developing solutions with their customers. This new focus brought the need for new equipment, leading to an investment in their first PULSE system from Brüel & Kjær.

Other Brüel & Kjær instruments typically used are triaxial accelerometers and a sound intensity probe, with Brüel & Kjær accelerometers and microphones used exclusively. PULSE hardware and software is used for research and design - and also records other important parameters, including oil temperature and pressure.

Ishibashi has already started diversifying with a joint venture company in China and has established a company in the US for servicing wind turbine gearboxes. In the near future they want to expand into other Asian countries on the basis of establishing joint ventures and subsidiary companies.

Ishibashi was founded in 1932 as a forging plant and began producing gearing in 1958. A joint venture with the German Flender group in 1989 became Flender Ishibashi, which led to active technical transfer in the group for about 12 years.
