Irie Koken Co., Ltd.

From semiconductor manufacturing equipment to space satellites and bullet trains. Irie Koken is a leading manufacturer of vacuum bellows and vacuum gate valves.

Business description

Irie Koken design, manufacture and sell the following metallic machine parts and vacuum equipment.
(1) Metallic bellows
One of Irie Koken’s main products, metallic bellows are widely used not only as an expansion joint of piping, but also as a vacuum part in the fields of semiconductors/liquid crystals, accelerators, nuclear fusion, nuclear power, railway, medicine, construction and more.
(2) Vacuum gate valves
Vacuum gate valves are used as partitions between vacuum chambers or for pressure adjustment in liquid crystal or semiconductor substrate production. We have a non-sliding valve series, KOSLARZE.
To handle the increase in size of glass substrates used in FPD production equipment, we were the first in the world to develop products of over 3,000mm processing size, using large-diameter hole gate valve “GARIVA” which uses a patented differential pressure cancellation mechanism. We have also developed high value added valves for the next generation of flexible substrates.
(3) Vacuum equipment
Irie Koken has participated in a number of Japan’s national projects such as JT-60SA and XFEL, and has manufactured beam profile monitors or special bellows for beam duct connection, etc. Our accumulated outstanding vacuum technology is used in the design and manufacture of vacuum chambers, related equipment and more.

Company profile

In 1966, Irie Koken started manufacturing bellows and expansion joints. Since then, thanks to our tireless and continuous research and development and many technological innovations, we have established unique technology in the vacuum field. From semiconductors and liquid crystals to space and railway applications, we have always provided reliable vacuum products.
With headquarters in Tokyo, we have sales representative offices, technical centers and factories (2 locations) throughout Japan. We’ve opened subsidiaries in China, Korea and Taiwan (sales agent) in order to deploy our business worldwide, especially in Asia.
Not only in Japan but also worldwide, we thoroughly and responsibly handle maintenance and concerns, which has won us a solid reputation with our overseas customers.
With fewer than 200 employees we have built a sophisticated integrated design, manufacturing and sales structure. On our factory lines, we employ TOC (Theory of Constraints) and have achieved three times more productivity without increasing manpower. Our achievement was lauded as a successful TOC implementation in ‘Velocity World 2009’ in the USA and has won worldwide acclaim ever since.
“Bring out superior individualities.” “Compete with reliability and technology.” “Share the joy of creating.” With these three goals firmly in mind, we will strive for excellence in the next 100 and 200 years.
