Exceptional quality and performance at a competitive price
Sigma-Netics makes customizable metal bellows that are ideal for a wide range of precision and non-precision applications. We produce metal bellows and related assemblies from hydroformed, electroformed nickel, edge-welded and diaphragm technologies. From reverse engineering existing designs to supporting new cutting edge applications our application engineers are eager to support your needs.
We produce four types of metal bellows and related assemblies: hydroformed, electroformed nickel, edge-welded and diaphragm.
Hydroformed Metal Bellows
Fully customizable and low-cost, our hydroformed metal bellows are ideal for a broad spectrum of applications including industrial and aerospace.
Hydroformed Bellows Assemblies
Our fully programmed soldering, brazing, and welding operations provide extremely consistent high quality joining methods as we combine our precision bellows with stamped and machined components to make value added assemblies.
Electroformed Nickel Bellows Assemblies
Extremely thin and extra small, these bellows assemblies offer unique solutions to some of the more challenging applications.
Edge Welded Bellows Assemblies
With the most stroke per size ratio of any bellows technology, edge welded bellows assemblies maximize performance in limited spaces.
Metal Diaphragm Assemblies
Our metal diaphragm and capsule assemblies provide highly accurate pressure-to-motion transfer for when accuracy and repeatability are paramount.
