Press hardening

Objective: limit part deformation.

Press-hardening is a technology for limiting deformations caused by hardening. During the quenching and cooling phase, the part is held in a tool to contain its geometry and deformations.

This type of hardening is particularly suitable for finished, thin and/or complex-shaped parts. There is no need for re-machining.

This process is carried out at the Thermi-Loire site.

Our process

Part type

The main families of parts processed include bushes, crown gears and bevel gears.

The size of the press accepts parts up to 16 inches in diameter (approx. 400 mm).

Heating

For reasons of flexibility, we have developed an electromagnetic induction heating system, enabling us to switch the system on and off as required. An optical camera measures room temperature.

Oil tempering

During oil quenching, the part is held in a punch-die tool. A robot handles loading and transfer under the press, for maximum productivity.

    Features and benefits

    limited deformations

    Press-hardening offers the possibility of hardening finished parts without deformation, or rather with a level of deformation compatible with the part's dimensional tolerance.

    Productivity

    Parts are hardened individually by robot, ensuring high reproducibility and productivity. Press-hardening technology is particularly well-suited to mass production.

    Complex shapes and finished parts

    This type of treatment is particularly suitable for thin-walled parts where machining techniques sometimes do not allow the parts to be reworked.

    Our FAQs

    What is vacuum deposition?

    Vacuum deposition is a surface treatment used to deposit a material or alloy on a mechanical part.

    The use of vacuum technology ensures a perfectly clean, non-polluting process.

    It is not subject to REACH legislation.

    What are the advantages of PVD technology?

    This process greatly increases resistance to wear, abrasion, friction and corrosion. As a result, component life is greatly extended.

    Standard thicknesses are of the order of 3µm and deposition is carried out on finished parts.

    What's the difference between PVD and PACVD?

    PVD is physical vapor deposition. The element to be deposited is obtained by evaporation or sputtering via a physical process. PACVD is plasma-assisted chemical vapor deposition. The element to be deposited is obtained from chemical reactions. Plasma enables this chemical reaction to take place at lower temperatures.

    What are the industrial applications of vacuum deposition?

    Vacuum deposits are classified into several categories: anti-wear, friction, decorative and biocompatibility. The applications are therefore very varied: automotive components, aerospace, tooling, cutting tools, medical devices, decorative parts...

    How do I choose the right deposit method?

    The deposition method depends above all on the nature of the coating to be deposited and the substrate.

    If the substrate cannot be heated to high temperature, the deposition must be carried out using low-temperature technology.

    If the coating to be deposited consists of a solid element (metal or graphite target), a physical process such as PVD is used. If the coating consists of a gas or liquid, a chemical process such as CVD or PACVD is used.

    What is the purpose of case-hardening? 

    Incorporate carbon below the surface of the steel part to improve fatigue and wear resistance on the surface, while maintaining good core mechanical properties.
