About IRIE KOKEN

IRIE KOKEN is a manufacturer that develops and manufactures high-precision metal bellows and vacuum equipment (vacuum bellows, vacuum valves, vacuum chambers, etc.) that utilizes vacuum technology.

Metal Bellows

We can manufacture both "formed bellows" that can be adopted at low cost and "welded bellows" with highly elastic using advanced welding technology. Our metal bellows are used as sealing materials to hermetically seal gases and fluids in a wide range of fields, including semiconductors, liquid crystals, vacuum equipment, accelerators, nuclear fusion, and railways.
Metal Bellows

Vacuum Valve

Vacuum valves require high sealing performance. We make use of our strength "vacuum technology", which we have cultivated through repeated trial and error, in our products.
In addition, we have established a large market share in the manufacture of large valves by responding to the demand for larger valve opening sizes that accompany the increasing size of substrates.
Vacuum Valve

Vacuum Components

We combine the welding and processing technology cultivated in bellows manufacturing with vacuum know-how to manufacture vacuum equipment such as vacuum chambers. Utilizing advanced welding and processing technology, we manufacture vacuum equipment that meets the performance requirements of our customers.
Vacuum Equipment

The reasons why IRIE KOKEN is chosen

Participated in numerous national projects.
A research and development driven company that continues to embrace the challenge of cutting-edge technology.

IRIE KOKEN has provided special metal bellows and other vacuum equipment to numerous scientific experiment facilities promoted by the government. The valuable research results obtained there are fed back to various products.

Suitable for semiconductor manufacturing equipment that requires advanced performance
Development and manufacturing system for high-quality products

Vacuum bellows and vacuum valves used in semiconductor manufacturing equipment require advanced performance to operate in a vacuum while preventing particle generation.

IRIE KOKEN has a technical center in Saitama Prefecture, which is mainly a research base for valves, and a bellows and vacuum equipment manufacturing plant in Ehime Prefecture, which boasts advanced processing capabilities and welding technology. We are building a design, production and inspection system that can create We can also customize products according to the customer's required specifications.

Careful after-sales service for cleaning and replacement
Support for overseas factories

Periodic maintenance and replacement are indispensable for components of semiconductor manufacturing equipment that require high precision.
At IRIE KOKEN, we value after-sales support for customers who have adopted our products, and in addition to regular replacement of parts, cleaning, and inspection, we also offer suggestions for improvements to solve problems in the manufacturing process. I will.

We also support replacement and maintenance of parts and equipment used in overseas factories.

Niche and top share
Original technology born from the spirit of doing what others do not

IRIE KOKEN has an advantage over other companies in manufacturing large valves that correspond to large openings of 3m or more in flat panel display manufacturing equipment. We have independently devised a mechanism that cancels the differential pressure between the atmosphere and the vacuum, which exceeds 10 tons, and boasts the top domestic market share.

In the railway vehicle field, our parts are used in high-speed trains such as the Shinkansen. For more than 40 years, there have been no major problems, and we have continued to use our products with a high level of trust.
