About us

For over 70 years, BMI has been designing and manufacturing premium vacuum furnaces for the heat treatment of metal parts.
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, aluminum 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…).

Vacuum tempering furnace type B5_R

The BMI vacuum furnaces of the B5_R family are designed for main low-temperature heat treatments and are often the perfect supplement to B8_T or VSE8_T hardening furnaces. These furnaces are particularly well suited to inert gas convection treatments after vacuum purge such as: tempering, annealing, ageing, stress relieving…

Oil quenching vacuum furnace type B5_TH

The BMI vacuum furnaces of the B5_TH family are designed for vacuum oil quenching applications. The heating chamber of this single-chamber furnace is directly integrated in the quenching chamber of the equipment. The installation is fully automatic and allows perfect reproducibility of the results and offers an economical alternative to the conventional transfer furnace solutions, with a controlled atmosphere.

News & Innovations

Retractable load thermocouples

The AMS2750E standard requires a perfect control of the heat treatment process and its implementation is strictly regulated. In the heat treatment sector, everybody is familiar with the use of thermocouples. In order to offer a better user experience, BMI developed an automated system of retractable TCs for its range of vacuum furnaces.

It all started with this project of collaborative engineering at the request of BMI's customer SAFRAN. The B54T furnace was recently commissioned in a brand new workshop in France for the repair of airplane engine components. This new workshop is the result of a joint-venture between SAFRAN and Air France-KLM.

This new system of retractable TCs makes it easier for the customer to comply with the AMS2750E. There is no doubt this innovation can benefit to other BMI customers, who are also submitted to the same requirements.
