BELFAB® Bellows, Components & Assemblies Technetics Group is a world leader in the design, production, and application of high precision sealing products incorporating edge-welded metal bellows. As a fore-runner in the development of this technology, we continually work to advance the state of the art by engineering unique design solutions that solve critical needs within complex mechanical systems. We also offer contract assembly services including design, fabrication, welding, upper-level assembly, testing, and packaging. A certified Class 100/ Class 1000/ Class 10000 clean room assembly environment is available as required. As an ISO 9001-certified organization noted for world class cellular manufacturing, Technetics Group has built its reputation on a foundation of total quality achievement. ENGINEERED SOLUTIONS Edge-welded metal bellows provide superior stroke capabilities and more precise spring rates than formed bellows, thus offering greater flexibility and control in the smallest possible place. Because edge-welded metal bellows are manufactured by welding both the inner and outer diameters of the bellow plates, they can be produced in a broader variety of materials than formed bellows, in which the number and shape of the bellows convolutions are limited by material ductility. Technetics Group's experience in optimizing bellows configurations for demanding applications gives you the edge you need to make your equipment perform better and satisfy your own product requirements. Our engineers will design a robust product that achieves the highest life-cycle possible while addressing all of your operating parameters, including stroke (lateral, angular and/or axial movement,) pressure (internal and external,) temperature and environment. Linear and thermal movements, vibration isolation and assembly offsets can all be accommodated with BELFAB®-designed bellows devices. Technetics Group has developed the rapid design/prototyping and production-ramp capabilities required for our demanding industry.
