Engineering, R&D Support
To provide engineering, R&D solutions quickly and cost-effectively, VPE’s team of materials scientists work closely with staff mechanical and electrical engineers. In addition, VPE has over 45 years of experience in developing new approaches to materials-joining challenges. Moreover, we provide materials science and fabrication technology expertise, contract research, and consulting for customers located in over four continents.
VPE’s Metallurgical Services include engineering, R&D support which have roots in:
VPE’s metallurgical services include the following precision brazing processes.
VPE’s metallurgical services include diffusion bonding which is used instead of precision brazing for end-use applications in which the use of a filler alloy might compromise intricate features and hermeticity. In addition, it is the preferred joining method for a number of microchannel devices, photo-etched laminates, gigahertz waveguides and antennas, corrosion-resistant manifolds, and microchannel heat exchangers. Furthermore, our history of developing new diffusion bonding process variations and improving current techniques ensures that we employ the best method for each application.
- Heat exchanger in addition to cold plate diffusion bonding
- Low-temperature diffusion bonding
- Additionally, low-force diffusion bonding
- Solid-state welding — in vacuum or controlled atmosphere and simultaneously applied force
- Trans-liquid phase (TLP) bonding
- Induction based
VPE’s metallurgical services include hot pressing, which has the following capabilities.
