For over 70 years, BMI has been designing and manufacturing premium vacuum furnaces for the heat treatment of steels. Our range of standard furnaces cover the following applications: oil/gas quenching, tempering, annealing, stress relieving, ageing, cryogenic treatment, etc... Our specific furnaces allow you to make high temperature brazing treatments, aluminium brazing, sintering, degassing as well as other specific processes such as IVD and APV. Our vacuum furnaces are available in a wide range of sizes and may be coupled with thermochemical treatment furnaces like low pressure carburizing, low pressure nitriding and plasma nitriding. Moreover, our heat treatment solutions comply with the requirements of the most demanding sectors (aerospace, medical, energy…) in terms of technical specifications and regulatory standards (AMS, BAC…).
