We manufacture CF flanges (ConFlat flanges) in accordance with all common standards and individual customer specifications. Our portfolio includes designs compliant with ISO 3669-2, DESY standards, as well as custom solutions for research and industrial applications. Our CF flanges are used wherever maximum leak tightness, high temperature resistance, and reliable process performance are essential – particularly in vacuum technology, coating systems, as well as research and particle physics.
Materials for the Highest Demands
Depending on the application, we manufacture CF flanges from carefully selected, high-purity, corrosion-resistant stainless steels:
- 1.4301 / AISI 304
- 1.4404 / AISI 316L
- 1.4435 / AISI 316LMo
- up to 1.4429 ESU / 316LN
These materials ensure reliable sealing performance and outstanding resistance, even under extreme operating conditions such as ultra-high vacuum (UHV) and elevated thermal loads.
Comprehensive Range of Nominal Sizes
We manufacture CF flanges in all standard nominal sizes up to an outside diameter of Ø 500 mm. This enables us to supply both standard components and large-diameter custom solutions.
Precision Manufacturing from a Single Source
As a specialist in CNC precision machining, we manufacture CF flanges entirely in-house. Our extensive manufacturing capabilities and state-of-the-art machinery ensure consistently high quality throughout every production stage – from rough machining to final precision machining.
This also allows us to manufacture complex custom geometries and customer-specific designs efficiently, economically, and with consistent repeatability.
Your Partner for High-Performance Vacuum Components
Whether you require a single custom part, a prototype, or series production, we support your CF flange projects with extensive technical expertise, flexibility, and uncompromising quality standards. Customers in research institutions and demanding industrial sectors particularly benefit from our comprehensive manufacturing expertise.
