Hydroformed Bellows

MW Components is the nation's number one manufacturer of metal bellows for the vacuum electronics industry. Our bellows and expansion joints are designed to absorb and reduce vibration and relieve structural stress from working under pressure, extreme temperatures, and other variables. We specialize in thin-wall bellows and welcome prototyping, low-volume production runs, as well as large orders.

We manufacture hydroformed metal bellows from various materials with multiple options for sizes and wall thicknesses and our metal bellows are designed specifically for each application. We work with you to determine the precise tolerances required and identify the exact production method and necessary ranges to meet your goals.
