Electrodeposited nickel bellows and electroforms

Electrodeposited nickel bellows and electroforms Drawing upon over 40 years of experience, Abssac now supports a full range of unique electrodeposited metal bellows and electroformed products. 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 proper thickness of spring quality metal on to the mandrel. The mandrel is then dissolved away leaving the precision finished product behind. The controlled electroforming process can also vary the wall thickness in different places on the same part for selective rigidity and flexibility allowing hollow parts with walls as thin as 0.0003in (0.008mm) for miniature applications including electrical bellows contacts and precision instrument applications. Nickel bellows can be produced with wall thicknesses up to 0.025in (0.64mm) thick. Electroformed ultra lightweight reflectors several feet in diameter have also been produced. Electroformed components are ideal for precision instruments, pressure responsive devices, hermetically sealed units and dynamic hermetic sealing, flexible bellows seals, electrical contacts (gold plated), bellows shaft couplings with exceptional torsional stiffness, custom engineered parts, high compression rates up to 60% of their free length, and miniature components.
