Vacuum Process Engineering

What Vacuum Process Engineering does

Vacuum Process Engineering, Inc. (VPE) is a privately held thermal engineering and contract manufacturing firm founded in 1976 and headquartered in Sacramento, California. The company specializes in science-based metallurgical and materials-joining services for mission-critical applications, with operations spanning over 150,000 square feet of design, laboratory, production, and quality assurance space (including a 20,000 sq ft clean environment laboratory). VPE employs 51-100 people and runs a fleet of vacuum, hydrogen, induction, and infrared brazing systems alongside the world's largest vacuum hot press furnace (chamber 60x120x120 in., temperatures to 1900°C, two 1200-ton rams producing loads to 4.8 million pounds).

The company's core service portfolio covers precision brazing (vacuum, aluminum, hydrogen furnace, induction, infrared), diffusion bonding, hot pressing, heat treating, thin film coating, complex assemblies, specialty cleaning, and materials testing/analysis (helium leak detection to 6E-11 atm cc/sec). Products are sold directly via wholly-owned subsidiary VPE Thermal LLC and branded VPE THERMAL: diffusion-bonded microchannel heat exchangers (MCHEs/PCHEs), the H2PC hydrogen pre-cooling heat exchanger family (pressures up to 1275 barg, SAE J2601 compliant), compact/miniature Series A and B heat exchangers, liquid cold plates, pinch-off and pump-out tubes, laminated and clad metal sheets, and Retrolite high-temperature retro-reflectors. In-house CNC machine shop capability (Haas VF and UMC platforms, Matsuura MX-520) provides turnkey design-to-production control.

VPE operates an engineer-to-engineer direct sales model with custom quote-based pricing, multi-year contracts, and an RFQ entry point on its website. The customer base is concentrated in aerospace and defense (NASA, Aerojet Rocketdyne, Raytheon, Lockheed Martin, Northrop Grumman, Boeing, L3Harris, Blue Origin, Lawrence Livermore NIF), semiconductor capital equipment (Applied Materials, Agilent), medical devices (Medtronic, named undisclosed majors), energy and hydrogen infrastructure (Sandia National Laboratories, Google), and industrial gas turbines (General Electric, Teledyne). The company holds AS9100:2016, ISO 9001:2015, ITAR registration, and ASME U/R/NB stamps with PED/CE marking on hydrogen products, and reports that approximately 90% of its work comes from existing or returning clients. It is founder-owned or independently held with no disclosed external investors.
