Thermal Processing for Aerospace, Aviation, Space, and Defense

Paulo has earned a reputation as a renowned provider of commercial and defense aerospace heat treating services.

We Help Aerospace Suppliers Fly Higher, Farther, and Faster

We have a long history of serving the world’s leading aerospace & defense primes and tiered suppliers. We understand the support you need to bring innovations to life. Here’s how we help.

Specialty Projects

Paulo has a long tradition of modifying and customizing processing equipment to meet customers’ unique specs. If no one makes the equipment we need, we’ll build it ourselves. And, thanks to our advanced process control automation, we often complete obscure, one-off or technically complex aerospace heat treatment jobs that other processors won’t touch. We also work hand-in-hand with engineers and metallurgists at our customer’s organizations to help with their research and development efforts.

Precision & Repeatability

We’re committed to doing the job right the first time. The aerospace and defense components we process cannot fail. It’s as simple as that. We see to it that they won’t with our precision furnace controls, automated processes, robust quality control and testing practices, and more. Dozens of sensors monitor around 1,000 different variables in real time and trigger alarms if out-of-spec conditions are observed.

Approvals & Certifications

Paulo was the first National Aerospace and Defense Contractors Accreditation Program (Nadcap)-certified thermal processor east of the Mississippi River and quickly achieved the Program’s merit status in both Cleveland and Kansas City. That means that Nadcap auditors were impressed enough by our sites, equipment, and process controls that they audit us every two years instead of annually.

Handling

Many of the aerospace heat treating projects we complete feature expensive, sensitive parts that must be handled with extreme care. In addition to using advanced equipment capable of fine-tuned treatment to exact specifications, we also carefully monitor how your components are handled and tracked through our processes.

Thermal Processing Capabilities for Aerospace

With vacuum, batch and continuous batch equipment running nonstop in our Cleveland and Kansas City divisions, Paulo has the solution treating and vacuum brazing capacity necessary to complete aerospace heat treating orders on short deadlines and turn them around quickly.

Hot Isostatic Pressing

HIP is opening a new world of possibilities for aerospace & defense OEMs, making new, lighter, and more sustainable materials and methods of manufacturing such as additive manufacturing viable for aircraft and space exploration for the first time. Additive manufacturing in particular has opened a new world of possibilities since it can achieve more complex part geometries than traditional machining. We offer hot isostatic pressing (HIP) in our Cleveland division with our Quintus QIH-122 furnace.

Solution Treating

We can create treatments that feature very slow ramp rates (down to around 1 degree per minute) and precision controlled cooling. This ensures that parts reach the required treatment temperature slowly and evenly, which promotes proper solutionizing.

Annealing

Annealing is often applied to aerospace and defense components as part of the manufacturing process to enhance the machinability of different materials. Depending on your material, we can provide full annealing, intercritical annealing, and sub-critical annealing.

Precipitation Hardening

While the annealing process is meant to dissolve a material’s constituent phases into a solution for ease of machinability, precipitation creates new phases in a material that help to increase strength.

Through Hardening

Through hardening is ideal for strength applications where parts need to sustain heavy loads during service life such as fasteners, nuts, bolts, brackets, and more.

Vacuum Brazing

Vacuum brazing is a specialized metal joining process that is well suited for aerospace components where tight tolerances are required. Brazing in a vacuum atmosphere yields bright, clean parts and high-integrity joints for hot section engine components.

Aerospace & Defense Parts We Process

If you’ve ever flown commercial, your plane probably included parts treated by Paulo. We’ve processed numerous components (including hot section engine parts) for Boeing 737, 757 and 787 Dreamliner aircraft in addition to many other commercial aircraft platforms.

Our military résumé is also exceptionally strong, having treated components in combat aircraft like Lockheed Martin’s F-35, Boeing’s F/A-18 and Fairchild-Republic’s famed A-10 Thunderbolt (better known by its nickname “Warthog”). In addition, we’ve completed specialty treatments of parts found in the turbine engines that power helicopters and tanks. We’ve treated submarine parts, too.

We even treated rocket booster fuel pump parts during NASA’s space shuttle program and have treated parts currently in orbit on the International Space Station.

  • Critical sensors
  • Radar and electronic systems components
  • Hot section turbine engine parts
  • Door locking hinges
  • Wing attachment bolts
  • Rocket booster fuel pump parts

Common Materials for Aerospace & Defense

  • Nickel-based superalloys
