The integrity of the ceramic-to-metal joint relies on the precision to which the individual parts are made. To meet these requirements the Company utilises C.N.C. machines to manufacture the wide variety of metal components required. This enables us to offer high quality stainless steel vacuum flanges to any of the international standards. Custom designs can also be accommodated.

Ultra High Vacuum Flanges
