What is Electroforming?

Simply stated the process of electrodeposition or electroforming involves building thin layers of metal onto a precision-machined mandrel and chemically removing the mandrel.  Although the technology has been around for centuries, primarily manufacturing consumer goods like CD’s and jewelry, only Servometer has perfected manufacturing convoluted, dynamic bellows electroforms for more than 50 years!

Our tightly controlled electroforming process is able to produce unique custom engineered components with the following features:
• Uniform wall thickness (0.0005″ to 0.025″), (0.13 mm to 0.64 mm) depending upon size
• Smooth finishes
• Near exact shape, form and function

We specialize in complex geometries with deep grooves, unusual shapes,  and other intricate design features. We can also combine aluminum mandrel components prior to plating to yield a seamless electroform assembly.

Watch how it Works!


The metal composition is critical to the performance and ruggedness of the electroform.  Servometer produces parts using our signature Cobalt-Nickel Alloy, FlexNickel®. The unique properties of our superior Nickel alloy outperforms other electroforming material choices such as Nickel and copper which are typically less robust. FlexNickel is easily able to meet the temperature capability and structural rigidity of metal yet retain the flexibility and weight of plastic as an example.  It can be used with other surface finishes including copper, gold, and silver or a combination depending upon media compatibility and conductivity.

FlexNickel mechanical properties:

• High tensile strength
• High elasticity
• Amendable to soldering, brazing and welding
• High Purity
• High Consistency
