The Electroforming Process
Electroforming, also known as electrodeposition, adds thin layers of metal onto an aluminum mandrel that is later chemically removed. While not a new technology, electroforming has multiple advantages, including the ability to produce wall thicknesses from 0.0005”-0.025” and near exact shape, form, and function. When combined with our signature cobalt-nickel alloy, FlexNickel®, this results in metal bellows that are strong, yet extremely flexible.
Product-Details
Electroformed Metal Bellows
Our electroformed metal bellows are manufactured using patented technology that provides superior flexibility and performance. Available in both circular and rectangular shapes, our bellows can have walls as thin as 0.0002 inches and are up to 25 times more sensitive than hydroformed bellows. They also provide large deflections with minute forces and can be designed to compress up to 60% of their free length.
Their exceptional characteristics make our bellows ideal for use in mission-critical industries like aerospace and defense. Get in touch with us to see how electroformed metal bellows could solve your challenge.
Miniature Bellows Electrical Contacts
Our micro-miniature bellows exhibit dynamic flexibility and can be manufactured with diameters as tiny as 0.020 inches (0.5 mm). These micro bellows are capable of compressing, bending, and cycling, and are helium leak-proof. As a result, they are ideal for use as precision micro-springs, miniature flexible micro-couplings, aneroids, pressure-responsive devices, electrical contacts, and flexible micro-hermetic seals that can withstand multiple autoclave cycles.
