Metallurgical innovation and manufacturing excellence requires specialized facilities equipped with the latest technology.  VPE offers over 150,000 square feet of manufacturing, laboratory, and QA space which utilizes high-tech equipment for design, assembly, joining, thermal processing, machining, welding and other metallurgical services to ensure the highest performance possible.

Vacuum Brazing Furnaces

Vacuum furnaces for vacuum, partial pressure, hydrogen, and argon atmospheres provide a clean environment where components will not react with oxygen, moisture, nitrogen, or other gaseous contaminants. The vacuum environment improves the wetting and flow of alloy and enables a completely fluxless process.

  • Operating temperatures up to 1,900°C (3,452°F)
  • Product size to 120 in. x 120 in. x 60 in.
  • Assembly weights in excess of 60,000 lbs.
  • Reactive materials brazing
  • Active metals brazing of ceramics

Aluminum Vacuum Brazing Furnaces

VPE’s extensive experience with aluminum vacuum brazing consistently results in high-integrity assemblies that meet the requirements of even the most demanding applications.  Through VPE’s aluminum vacuum brazing practices, fillet sizes can be minimized, joint voids can be virtually eliminated, alignment of critical features can be maintained, and hermetic joints can be routinely produced.

  • Aluminum-brazing furnaces of different sizes
  • Product size to 62 in. x 59 in. x 38.75 in.
  • Producing assemblies ranging from ceramic-to-metal terminations to large-format cold plates, radiators and microwave devices.

Hydrogen Furnaces

VPE’s hydrogen furnaces reduce oxides present on the surface of the materials and provide a clean environment for joining ceramics, copper, stainless steel, Kovar, and other non-reactive metals.

  • Operating temperatures up to 1,250°C (2,282°F)
  • Product size to 18 in. x 18 in. x 100 in.
  • Controlled dew point processing enables VPE to selectively oxidize and treat product for specialized applications.
  • Vertical and horizontal loading furnaces

Thin Film Coating Systems

VPE’s experience with a variety of thin film coating methods ensures that we use the most appropriate technique for each application.

  • Electron beam
  • Ion plating
  • Sputtering
  • Reactive sputtering

Induction & Infrared Braze Systems

VPE uses induction heating methods to process and braze components and staged assemblies in vacuum, hydrogen, and air environments.

  • Rapid precision single-piece production brazing
  • Fast ramp brazing and thermal processing
  • Vacuum, hydrogen inert gas, and air environments

Diffusion Bonding Furnaces

These furnaces allow for a dynamic force application to components being bonded.  Diffusion bonded assemblies can incorporate microchannel, thin foil members, heavy cross sections, and complex geometrical features without the liability of feature distortion or filling of microchannels by braze alloy.

  • Temperatures to 1,900°C (3,452°F)
  • Applied force to 2,400 tons (4,800,000 lbs.)
  • Product size to 120 in. x 120 in. x 60 in.
  • Assembly weights in excess of 60,000 lbs.
  • Long cycle, minimum strain

Hot Pressing Furnaces

VPE is well equipped with hot pressing furnaces for the densification and particle joining of ceramic and metal powders.  VPE is able to use any of its diffusion bonding furnaces as hot pressing furnaces, allowing for small, medium, and large sized batches.

  • Controlled atmosphere under vacuum to avoid contamination
  • Interface assisted
  • Long cycle and minimum strain
  • Partial Pressure Control for up to three gases
  • Vacuum-based
  • Applied dynamic load to 4,800,000 lbs.

The World’s Largest Hot Press

VPE currently owns the world’s largest vacuum hot press furnace, which is perfectly suited for brazing, bonding, and hot pressing.

  • The usable chamber area is 60 in. x 120 in. x 120 in.
  • Rated for temperatures in excess of 1900° Celsius in vacuum and partial pressure atmospheres.
  • Two independent 1200 ton rams allow for loads to 4.8 million pounds
  • Ten high accuracy load cells allow precision force and precision control on the production elements.
  • Assembly weights in excess of 60,000 lbs.

Machine Shop

VPE’s machine shop continues to increase its capabilities, providing complex and precision parts for many industries including aerospace, commercial, medical, and the Department of Defense.

  • Over ten main machining centers and growing, including  Vertical, Horizontal, 5-axis, Turning, and EDM
