Product Information

Metal Bellows

Metal Bellows

IRIE KOKEN's basic technology lies in the production of metal bellows.
In particular, we are focusing on the precision bellows field that requires high
performance and high reliability, and are widely used in the vacuum field.

Go to detail page

Welded Bellows

Welded Bellows

This metal bellows is manufactured by
alternately welding the inner and outer
diameters of thin metal plates on precision
discs and joining them together.

Molded Bellows

Formed Bellows

Historically older than welded bellows,
various manufacturing methods have been
devised. The most commonly used methods
are mechanical roll forming and hydraulic
bulge forming.

Flexible Tube

Flexible Tube

A flexible tube is a relatively small-diameter
bellows used for piping in equipment that
can be freely bent.

Vacuum Valve

Vacuum Valve

It is for isolating vacuum from vacuum and vacuum from atmosphere. In addition to being used to isolate various processes in manufacturing displays and semiconductor substrates, it is also used to adjust the pressure of the vacuum chamber by placing it between the vacuum chamber and the vacuum pump.

Square Gate Valve

Square Gate Valve

This is a high-quality square gate valve that
can also be used for next-generation LSI and
LCD manufacturing equipment.
A high level of dust-free operation is strictly
required in recent process lines for highly
integrated devices, compound
semiconductors, and optical devices.

Round Gate Valve

Round Gate Valve

MARINA is a round pendulum type valve with stable sealing performance, simple structure and compact design. We support everything
from semiconductor manufacturing
equipment to large FPD and organic EL
manufacturing equipment.

Go to detail page
Large Gate valve(Square)

Large Gate valve
(Square)

Employs a differential pressure canceling mechanism, making it easy to increase the size of the seal opening (experienced from G5 to G10), improving the reliability of sealing
performance, and eliminating the need for
tilting the valve plate, resulting in stable
sealing operation and improved reliability.

L-type Valve(Angle Valve)

L-type Valve
(Angle Valve)

The high-vacuum angle valve is a long-life
vacuum valve with a built-in molded/welded bellows that has a proven track record.

Vacuum Equipment

Feedthroughs

We provide highly customized semiconductor components and equipment as a supplier of manufacturing equipment for semiconductor devices with various applications and demanding performance requirements.

We also offer a variety of standardized feedthroughs. They can be used up to the high vacuums. (The bellows sealed linear feedthroughs can be used up to ultra-high vacuum.) The bellows type uses our own highly reliable metal welded bellows.

Bellows Type Rotary Feedthrough Machine

Bellows sealed
rotary feedthroughs

IRIE KOKEN's bellows-sealed rotary feedthoughs are available in high-precision roatary feedthoughs and compact roatary feedthoughts as a unit to conduct rotational motion from the atmmosphere side to the vacuum side. They can be used in regions up to high vacuum because metal welded bellows are used for isolation between the vacuum and atmosphere.
