Maximize Precision and Productivity with CFC Vacuum Furnace Racks
Joerg Demmel • May 13, 2025
Born from the demands of space exploration, Carbon Fiber Carbon (CFC) has found a powerful second life in the world of industrial heat treatment. This advanced material—capable of withstanding temperatures beyond 2,000°C—has become a game-changer for companies seeking to improve precision, reduce cycle times, and dramatically extend the lifespan of their fixtures.
Today, Vacuum Furnace Fixtures and Vacuum Furnace Racks made from CFC are setting new standards in performance. Whether in aerospace, automotive, or tooling industries, businesses are replacing outdated steel systems with custom CFC solutions that deliver unmatched efficiency and throughput. It’s not just an upgrade—it’s a transformation in how we approach high-temperature processing.

What Makes CFC Fixtures Game-Changing?
Let’s start with a powerful idea: what if the material that once survived re-entry from Earth’s orbit could now extend your furnace fixture's life and double your throughput?
CFC—Carbon Fiber Reinforced Carbon—originated in aerospace. Its strength under extreme conditions makes it the ideal material for
Vacuum Furnace Fixtures. Why? Because unlike steel or other alloys, CFC maintains its form and structural integrity even at temperatures above 2000°C.
Thanks to its low thermal mass and chemical inertness, you benefit from:
- Reduced cycle times
- Minimal contamination risks
- Consistent heat distribution
- Lighter fixture weight
- Energy efficiency
These aren't just upgrades; they’re transformational improvements.
Benefits of Our Custom Vacuum Furnace Racks
Not all racks are made equal—and we don’t do them off-the-shelf. At High Temperature Concept, every Vacuum Furnace Rack is custom-engineered to meet the exacting demands of your tools and components.
Here’s what you get:
Feature
- Precision CFC tray and rack design
- Lightweight structure
- Oil quenching compatibility
- Long service life
- Cleanroom-ready surfaces
Benefit
- Exact fit for complex geometries
- Easier handling and faster heating/cooling
- Suitable for harsh treatment environments
- Reduced downtime and replacement costs
- Ideal for aerospace and medical components
You don’t just get a fixture—you get peace of mind, throughput, and repeatable performance.
Real-World Applications and Success Stories
After more than 30 years in the user industry, we've helped many heat treatment shops across the U.S. and Europe optimize their furnace performance.
Take, for example, a leading tool manufacturer that switched to our custom Vacuum Furnace Racks for annealing and oil-quenching applications. Their results?
- Cycle time reduced by 35%
- Rack lifespan increased by 400%
- Furnace Throughput increased by 70%
- Fewer part deformations
As a result, they scaled up production and saved thousands annually.
This is the kind of transformation we’re proud to deliver with true German Engineering Quality, proudly Made in the USA.
Boost Your Furnace Throughput—Up to 100%!
We like to say, “Don’t be satisfied with less.” And with our CFC-based Vacuum Furnace Fixtures, you really don’t have to be.
In fact, many clients report a throughput increase of up to 100%, simply by upgrading their fixture system. How?
- CFC allows different designs with smaller space because of it’s outstanding material properties at the highest temperatures
- Reduced preheating and cooling time
- Higher component density per load
- Minimal distortion = fewer rejected parts
- Durable enough to run longer without replacements
This isn’t wishful thinking—it’s CFC reality, proven by clients, and supported by continuous innovation.

FAQs About CFC Vacuum Furnace Fixtures
Q1: Why choose CFC over steel or molybdenum for vacuum furnace applications?
A:
CFC withstands higher temperatures, has lower thermal mass, and offers significantly longer service life compared to traditional metals. This makes it more energy-efficient and cost-effective in the long term.
Q2: Can you customize racks for complex geometries or processes like oil quenching?
A: Absolutely. Our Vacuum Furnace Racks are designed in collaboration with your team to fit specific parts, processes, and thermal profiles—including oil quenching.
Q3: How do CFC fixtures improve furnace throughput?
A: They heat and cool faster, reduce energy usage, and allow much tighter load arrangements because of its outstanding mechanical and thermal properties at highest temperatures —resulting in throughput increases of up to 100%.
Q4: Are your fixtures suitable for aerospace or medical parts?
A: Yes. Our CFC racks are compatible with cleanroom standards, making them ideal for critical applications with no contamination risks.
Q5: What support do you provide post-purchase?
A: Because of the chemical inertness of CFC and our tested designs, usually there’s no rework and therefore no support needed. If there’s anything we can help with, ask our team. From design consulting to maintenance tips—we are ensuring your CFC solution continues to perform for years.
