IRIE KOKEN has been in business for about 60 years, and with metal bellows technology at the core, we have been striving for technological innovation, research and development, and productivity improvement in order to provide products that enrich people's lives and contribute to the creation of a more affluent society.
In the early days, we manufactured bellows such as expansion joints for air conditioners, but later we entered the field of high vacuum technology with the production of parts for accelerators. Today, we offer a wide range of products for semiconductor and FPD manufacturing equipment, including vacuum bellows, vacuum gate valves, vacuum equipment, and other vacuum equipment accessories. Vacuum technology has now developed into an indispensable technology in all situations and industrial fields. The world created by metal expansion joints ranges from everyday items such as electronic components to the world of cutting-edge technologies such as semiconductor manufacturing, atomic and molecular ultrafine particle engineering, and space development. Through these technologies, we will continue to provide society with reliable products.
