Products:   High Performance NiColoy® Bellows and Assemblies

Electroforming is the only bellows fabrication method capable of producing stress-free components. In other manufacturing methods - rolling, welding, hydroforming - the finished bellows contain welded seams, wall thickness variations, deformation and/or heat induced stresses, compromising the components' strength, durability and performance under load. In electroforming, metal is uniformly electroplated onto a conductive substrate of the desired configuration, called a mandrel. After the plated layer reaches the required thickness, the mandrel is dissolved by chemical means, leaving behind a stress-free electroformed bellows as shown in the illustration. Electroformed NiColoy® bellows (sometimes called 'electrodeposited bellows') outperform other bellows due to their stress-free nature and high alloy strength, especially in precision dynamic applications.
As dynamic, elastic components, bellows uniquely benefit from NiCoForm's advanced electroforming technology and its trademark high performance alloy, NiColoy®. Our mass electroforming technique produces stress and pore free bellows with otherwise unattainable part-to-part consistency. Freedom from stress assures the materials' reliable performance in extension, compression, bending and rotation. NiColoy®'s combination of high elasticity, tensile strength, corrosion resistance and low tendency for crack formation assures the unsurpassed characteristics of NiColoy® bellows, far exceeding those of their nickel counterparts.
