Thermi-Bugey

THERMI-BUGEY makes its expertise available to plastic injection molders, toolmakers and precision mechanics.

THERMI-BUGEY, a partner for molding mechanics

Located near Oyonnax, in the heart of Plastics Valley, THERMI-BUGEY was created in 1987 to meet the industrial requirements of moldmakers, toolmakers and precision mechanics .

The quality, reliability and speed of our services are ensured by a competent, available and motivated technical team, and by high-tech equipment.

THERMI-BUGEY has all the technologies required for the mechanical engineering market: vacuum treatment, nitriding, PVD and DLC coatings. Bring together all heat treatment solutions from a single source, with vacuum treatment, low-pressure nitriding and vacuum deposition technologies (synergy with THERMI-PLATIN).

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

For local customers in the Oyonnax area, we have our own shuttle service to handle the transport ourselves and relieve our customers of the administrative burden.

Focus on press hardening and its advantages

Press-hardening serves a very specific purpose: to prevent part deformation during the rapid cooling phase induced by quenching. This method improves the performance of steels by giving them a martensitic structure, without the need for reworking. Designed for large production runs of parts with complex geometries, [...]

Focus on martensitic hardening and its advantages

The aim of martensitic hardening is to bring out a specific constituent in steels, called martensite, to make them harder and more resistant to wear and mechanical stress. It is one of the oldest known heat treatments of metals, and is still used today, thanks to its effectiveness and the [...].

Thermochemical treatments for austenitic stainless steels

Stainless steels are metals renowned for their anti-corrosion properties. Since its creation, THERMI-LYON has been offering its customers a range of thermochemical treatment solutions for austenitic stainless steels on a subcontracting basis. Over 60 years' experience in the treatment of stainless steels [...]

Steel bars of various sizes, illustrating annealing and tempering processes

Annealing and tempering: what are the differences and what are the different types of annealing?

Annealing and tempering are among the heat treatment techniques applied mainly to steels (copper alloys, aluminum and titanium too). Both methods involve heating parts to precise temperatures, which vary according to the process, but do not serve the same purpose. There are two main types of annealing [...].

A closer look at step quenching and its advantages

Staged quenching is based on cooling in stages. It includes a traditional initial heating phase, to reach a given temperature, but requires controlled cooling to be divided into several stages. This process offers a number of advantages, including a reduced risk of breakage or deformation, compared to quenching with [...].

Bonded varnish Complementary treatment to heat treatment

Why choose glide varnish as a complementary treatment?

Bonded coatings are an excellent way of improving the coefficient of friction of metal parts. Applied, possibly following a heat treatment operation, it ensures that the parts slide better together and reduces the risk of seizing. This technology is used particularly in the construction and screw industries, but also in the [...]
