New CFC Racks meet the highest customer requirements

Joerg Demmel • December 4, 2025

New CFC Racks and Fixtures in heat treatment with high quality CFC Grids and Posts stand out. Do you know why?


These racks are not only lightweight but also don't change form or dimensions over time, so they last longer than many (any?) others. 

Some other Racks and Fixtures have been running successfully for over 10 years. Have you ever seen any steel rack that does so?  The Rack shown above is brand new. 

One unique selling point is our CFC posts, which are used instead of graphite or steel. 

Only well-designed CFC Racks with CFC posts and related parts enable the highest process capabilities and reliable automated handling in the heat treatment industry for years, if not decades. 

This saves a lot of time and money and makes the US sides competitive, like the one above.

There are other benefits, such as energy savings and improved part quality. Ask us for details. We are here to help.

And, the best thing, do you know what the customer said?

"Jorg has been a great partner to work with. His team is knowledgeable and responsive. Design phase was very easy due to his understanding of the materials and processes. Quality of product and lead time both exceeded expectations on all orders to date."
