The electroformed product available from Abssac Limited is a formidable package. For those engineers familiar with the traditional electroforming process we are offering a new way of looking at both complexity of shape, wall thickness tolerance, integral strength and capability.
Ask yourself.........Do you know what an electroform is ?
Electroforms are manufactured by a process of electrodeposition; by building thin layers of metal onto a precision machined mandrel with the quality and dimensional accuracy being of paramount importance. Then, by refining the electroforming process, parts with unusual shapes, thin walls, deep crevices and other design features can be controlled to ensure the highest part quality.
With the specialized electroforming process, most custom electroforms require no significant tooling, which can allow for several prototype variations to be supplied and evaluated, as opposed to being locked into a design by expensive dies or moulds. A major advantage of the electroforming process is the ability to provide close tolerance steps and dimensions not easily produced with stamping or other mechanical processes.

The designs are limited only by your imagination.
Bellows Shaft Couplings
(Flexible Torque Transmission) - Utilizing the low inertia, zero backlash and high torsional rigidity characteristics of a bellows a range of flexible couplings is available. Inherently, absorbing angular and parallel shaft misalignments in combination with axial movements, while precisely transmitting motion and torque is there key strengths. Ideally suited for coupling to encoders and resolvers in precision positioning applications.
(Rigid, Lightweight Structural Forms) With a truly refined process, custom designed Electroforms and thin walled hollow metal components, for use in a myriad of high tech applications can be supplied. These often unique Electroforms can be used as moulds, coldshields or radiation shields, waveguides, for precision tubing, and light weight structurally rigid components. They can be made as small as 0.5mm (0.020 in) diameter out of nickel, copper, gold or silver, or a combination of all.
Servometer Electroforming Process
The process begins with a piece of alluminium stock or bar.
Next the internal geometry of the electroform or bellows is machined into the alluminium. This machined part is called a manderal.
After inspection, nickel, copper, gold, silver or combinations therof are electrodeposited onto the mandrel to precise wall thickness.
Following post-plate inspection, the plated mandrel is trimmed to produce the desired end configuration and dimensions.
Finally, the alluminium mandrel is dissolved in caustic solution, leaving behind the completed electroform or bellows. At this point special finishes or coatings may be applied. Bellows are leak-tested and spring-rated as required.
