Hydroforming is a fabrication process which uses high-pressure hydraulic fluid to compress unheated metal material into the die. Several materials and secondary procedures and finishes can be used with this process to achieve your desired end-result.
- This process easily forms complex shapes with intricate geometries.
- Hydroforming produces lightweight parts with greater stiffness to weight ratio.
- Per unit, costs are lower than other forming alternatives.
- Various pressure, temperature, stroke, and dimensions available depending on the material used.
- Extremely high life cycle rate (Up to 1,000,000,000 cycles (Theoretical “Infinite” Life)).
- Achievable leak rate (up to 1 x 10-9 cc He/sec @ 1 atm).
Formed bellows are produced in two ways; hydroforming & mechanical forming. Both are produced by reworking tubes into convoluted bellows. Hydro-formed bellows will use a die and high-pressure fluid to form the convolutions. Mechanically formed bellows will use a die and a roller to cold work the convolute shape. Formed Bellows have lower performance characteristics with thicker walls but cost less to manufacture.
MW produces a full line of bellows assemblies to complement our metal bellows. We manufacture bolt-style and clamp-style bellows assemblies, flanges, valve assemblies, and expansion joints. Every bellows assembly we make is ultrasonically cleaned prior to welding and helium leak tested after to ensure weld integrity and defect-free construction. Bellows assemblies are ready for immediate installation, saving you time and money in the production process.
Our high-quality braided hose is designed for high-pressure applications. It provides the protection needed for the convoluted inner hose to withstand high pressures and for vacuum or partial pressure applications requiring protection from hazards. Our stainless steel braided hose is found on NASA’s Curiosity Mars Rover, on commercial spacecraft still in development, and countless other applications.
We take pride in manufacturing top-quality, metal flanges for all types of assemblies. Flanges help strengthen other vacuum components while holding them in place. They provide leak-proof connections for braided hoses, bellows assemblies, and other components. Our metal flanges are designed for years of non-stop service in severe working conditions.
