Quartz-To-Metal Seal Assemblies
The Performance Benefits of Bomco's Moly-Cup Seal Assemblies
| Today, Bomco's seal assemblies are used in a wide variety of electro-optical applications including high wattage lamps, lasers, and semiconductor development and manufacturing. Depending on the application, Moly-Cup seals offer design engineers some very distinct advantages: |
¤ smaller, more compact design configurations ¤ operating temperatures to 900ºC in protected environments, to 350ºC in air ¤ quick thermal shock cycling from 1000ºC to liquid N2 ¤ more power into the quartz envelope ¤ extended product life ¤ higher product reliability ¤ lower product costs |
Standard Moly-Quartz Seals
Standard Moly-Quartz Seals are available in cup sizes from 1/2 inch to 2 inch as specified on the chart below. When ordering, please specify the proper part number, the hole size if desired, and whether the cup end should be cut off.
Standard Flange-Mounted Moly-Quartz Seals.
In a very exacting process, Moly-Cup seal assemblies are TIG welded to specially prepared standard vacuum flanges. These assemblies are available with windows set perpendicular, at a specified angle or as straight tubulations, 100 percent tested for vacuum tightness. Windows will be supplied as commercial grade ground and polished synthetic quartz. Flatness is 10 waves and will be torch-fused, producing some edge distortion. Brewster windows are normally .100" inch thick. Consult us directly for details. To aid in design, maximum bore through any transition will be approximately .100 inches less than the diameter of the Moly-Cup. Perpendicular windows are .06" thick.For maximum seal sizes that can be welded or brazed into standard knife-edge type vacuum flanges, see table.
