Metal Bellows - Key enabling technology for a wide range of engineering applications

The versatile metal bellows play an essential role in controlling pressure, vacuum and motion, in a broad array of machine components and assemblies across numerous industry sectors. The process begins with a piece of aluminium stock or bar. Next the internal geometry of the electroform is machined into the aluminium to produce a mandrel.

Spot light on using Gold for Electroforms

Electrodeposited products are formed by machining a precision mandrel to the shape of the desired form (or inside of the bellows) and then depositing the correct thickness of quality metal on to the mandrel. The mandrel is then dissolved away leaving the precision finished product behind.
