THERMI-LYON, a true technological showcase

Historically the group's first site, THERMI-LYON was created in 1960 to meet the needs of the Rhône-Alpine mechanical engineering industry.

Its high level of investment in human resources and technology has enabled it to extend its reach nationwide and internationally.

THERMI-LYON has played a major role in the development and industrialization of new heat treatment processes, and has won several MIDEST and A3TS innovation awards.

New processes have been deployed to improve the wear and galling resistance of stainless steels without compromising corrosion resistance: THERMI-SP®.

This powerful multi-treatment unit meets a wide range of customer requirements.

All equipment is linked by a supervision network, enabling continuous data acquisition and remote interrogation.

Vacuum deposition specialist

THERMI-LYON has invested heavily in the development and mastery of DLC coating using PACVD technology.

An adapted environment (clean room) has made it possible to create a dedicated workshop for coating tribological layers.

Recently, THERMI-LYON developed a new range of DLC deposits based on PVD technology. This new development makes it possible to produce dehydrogenated carbon-based coatings for specific applications, depending on the working environment.

Since its creation, THERMI-LYON has adapted to different contexts and set up an organization to meet the requirements of the automotive, aerospace and medical markets, as well as the special machinery sector.
