Design Innovations

Aerospace manufacturers—pursuing ever greater performance and fuel efficiency—now need to accommodate much higher engine operating temperatures and deliver new levels of capability and reliability. These manufacturers are under constant pressure to extend cycle life, reduce maintenance, and lower overall costs of critical parts and assemblies. For innovative customers in aerospace, we welcome the chance to design and build all-metal components that meet or exceed the most extreme specifications, without the reliability and maintenance risks associated with carbon and elastomers. If it hasn’t been done yet—or hasn’t yet been done right—we’re here to help you tackle the challenge. 

• Hydro-mechanical Fuel Controls
• ECS Bellows
• Volume Compensators
• Fuel Drain Couplings
• Kiss Seals for Bleed Air Valves
• Accumulators for EHA Flight Control Systems
• Accumulator for Landing Gear Systems & Thrust Reversers
• Hydraulic Systems
• Braking Systems
• Anti-Ice

Engineering

We develop new products (and reimagine conventional ones) for aerospace components such as thermal valves, accumulators, high temperature seals, feedthroughs, and more. We design for extremes of temperature, pressure, and corrosive environments—especially when high lifecycle, zero leakage, maintenance-free and high performance is essential. Our process is fast and efficient, with full in-house resources, including: 3D solid modeling (rapid proof-of-concept), finite-element structural analysis, flow simulation and sizing—along with all required qualification and documentation. We hold FAA, PMA, EASA, and other global certifications.

A tier-1 flight controls company was designing an innovative system for a new large commercial aircraft and required a hydraulic reservoir. EHA guidelines require that these reservoirs be 100% maintenance free. 

Our customer, a large commercial airframer, challenged themselves to produce a next-generation aircraft concept that would deliver significantly lower total life cycle costs—including dramatically reduced-maintenance requirements.

Our Company

Performance-driven organizations turn to the Senior Metal Bellows team of engineers, designers and fabricators—as passionate and committed colleagues—in order to push the boundaries of their disciplines. We have helped them accomplish their objectives from the deepest parts of the ocean floor to the far reaches of outer space. 

Confidence & Reliability

As part of the Senior family of companies, we offer you the confidence and reliability of a global organization with significant resources and demonstrated stability.

We are proud to have played a part in some of the historic scientific, medical, and military breakthroughs of the 20th Century, and look forward to serving you, as you pursue tomorrow’s “impossible” goals. We hope you will consider us a ready and proven resource.

Fabrication & Testing

We bring our innovative designs to life in an advanced manufacturing facility where state-of-the-industry processes are executed under the highest standards. Seasoned technicians supervise advanced fabrication in:

• Metal joining & forming with vacuum furnaces, and hydraulic presses to 1200-ton strength
• Precision welding including methods such as TIG, laser, and electron-beam
• Metal finish & metallurgy, with two automated cleaning lines featuring advanced cleaning, passivation and etching capabilities
• Functional testing, including extreme environmental chambers, spring rate, tensile, and acceptance testing. Performance validation for all parameters.

Our customer—a large gas turbine manufacturer—required an automatic thermal valve that would actuate at temperatures exceeding 650°F. At the time, no existing thermal actuator technology could meet this specification.
