In the industrial market, where new approaches and actions are in demand at all times, KYK has been providing a variety of innovative atmosphere contorol for more than 60 years.

This experience has greatly contributed to the growth of carbon fiber for the aircraft and custom automotive production in the automotive market.

With its eyes focused on the global environment,
KYK’s temperature & atmosphere-based challenge continues.
Please look forward to the development of new industrial furnaces,
which KYK will open up as the NEXT STAGE

Furnace for CF/CF Application

In 1984, Opened a new page for KYK

In 1984, introduction of an ultra high temperature furnace opened a new page for KYK.

Support from the prefecture and small and medium sized research and development enterprises lead to the development of a new Ultra-high prototype furnace that achieved 3000℃.
The technology that began at that time continues with more than a quarter century of high performance carbon fiber production.
