About Vacuum Process Engineering

Vacuum Process Engineering develops and manufactures joined assemblies using diffusion bonding and precision brazing. Its Sacramento operation works with metals and ceramics for applications including microchannel devices, manifolds, sensors and thermal-management assemblies. Diffusion bonding joins layered parent materials without a conventional braze filler; vacuum brazing provides a separate route for assemblies requiring filler alloys and controlled furnace processing. Engineers can discuss material combinations, joint design, fixturing and thermal profiles with the company before production. VPE also advertises heat treatment, specialty cleaning, materials testing and machine-shop services. Its contact page identifies separate headquarters and shipping addresses in Sacramento.
