High Temperature Thermal Processing
Industry's demand for high-performance materials has led to the development of sophisticated thermal processing furnaces that produce controlled-vacuum and pressure environments over a wide range of temperatures. Centorr Vacuum Industries has been in the forefront of this technology for over 40 years. Our furnaces make new materials with tailored properties possible, and provide existing materials with vastly improved performance characteristics. We use processes ranging from sintering, brazing, annealing and melting, to hot pressing, diffusion bonding, Chemical Vapor Deposition (CVD), degassing and other advanced materials treating methods. Remember the winning combination of Competence, Versatility and Innovation and rely on Centorr Vacuum Industries for all of your high temperature processing needs, from laboratory testing and pilot plant applications through to full batch semi-continuous and continuous production-scale furnaces.
