Electroformed bellows are seamless, ultra-thin metal bellows produced by precision electrodeposition. They are designed to provide flexible sealing, precise motion compensation, and low-force response in compact precision systems.
Electroformed bellows are produced by depositing metal onto a precision mandrel and then removing the mandrel to create a seamless, ultra-thin bellows structure. This process enables low spring rate, high flexibility, and highly customized geometries for precision applications.
Electroformed bellows are ideal for compact precision systems where seamless construction, ultra-thin walls, low spring rate, and reliable sealing performance are required.
Minimum OD: 0.05mm
Minimum wall thick: 0.005mm.
Its sensitivity is more than 25 times that of hydroformed bellows.
Standard lifespan can reach 100,000 cycles, and it can be designed for unlimited cycle life.
No risk of pollution, and has a leakage rate as low as 1x10⁻⁹ cc He/sec.
The compression stroke can reach 60% of its free length.
Lightweight with high strength, corrosion resistant; temperature range -253°C to 177°C.
We manufacture precision mandrels that define the internal geometry, convolution profile, and dimensional accuracy of electroformed bellows.
We provide brazing, laser welding, bonding, and other joining methods according to customer requirements, enabling bellows to be delivered as integrated assemblies.
Each product can be inspected for appearance, dimensions, spring rate, leak rate, and cycle life before shipment. Additional tests such as pressure testing and non-destructive testing can also be performed according to customer requirements.
We design customer-specific electroformed bellows based on operating conditions, installation space, stroke, spring rate, pressure, material, and surface requirements.
