Precision welded bellows assemblies like these are available as complete units, or using your furnished end pieces. This minimizes risk of damaging the thin, electrodeposited nickel bellows.
The ultra-thin walls of a bellows makes them vulnerable to damage, especially from heat, unless handled expertly. Even the “cool” area of the tiniest soldering flame can overheat a 0.001-in. bellows wall to 1,000°F., immediately ruining it.
This manufacturer’s bellows subassembly services can provide sealed, evacuated, or backfilled bellows assemblies (with gas or liquid) for pressure and temperature-responsive applications. Specialized gold, silver, copper, or parylene copolymer coatings for custom requirements can also be provided.
