Flange components create the connections for individual vacuum components and are required for every vacuum system. In doing so, the vacuum technology places high demands on the materials used as well as on the manufacture of the components.

The vacuum components are helium leak-tested and show leakage rates better than 10-10 Pa · m3/s for ISO-KF, ISO-K/ISO-F flanges and 10-11 Pa · m3/s for CF and COF flanges. All our flange components are welded from the inside for an ideal vacuum. If the geometry does not permit this process, the flange is completely welded through to prevent any leaks such as gaps and blind holes. Suitable materials, clean surfaces and special cleaning methods with industrial machines guarantee low desorption rates. Welded components are finely sandblasted with glass beads or pickled. Alternative surface treatments such as surface grinding, electro-polishing or annealing are available upon request.
