BELLOWS— flexible, spring-like, precision-engineered components—are used in pressure or volume compensation applications. They are also used as actuators, seals, feedthroughs, and more in industries including aerospace, semiconductor, medical, and industrial. The term “bellows” encompasses several unique technologies, each with its own performance characteristics, materials, and manufacturing techniques. Read on to learn the differences between electrodeposited, edge-welded, and hydroformed bellows.
