ThermoLine-VAC
Retort furnace

The ThermoLine-VAC series includes industrial furnaces and high-temperature furnaces, suitable for vacuum and process gas. Retort furnaces as so-called hot-wall furnaces offers a cost-effective alternative to large-capacity chamber furnaces. Depending on customer requirements, retort furnaces are designed for high vacuum (1*10-6 mbar) as well as for all process gas atmospheres (in particular argon (Ar), nitrogen (N2), hydrogen (H2) and mixtures thereof).

Custom-made retort furnace

Depending on the retort material, systems for temperatures up to approx. 1200 °C can be realized. The retort is heated from the outside with a conventional furnace. We also manufacture these high-temperature furnaces according to the customer's special requirements. This enables to achieve the best possible results for stress-relief annealing of components, sintering and debinding of ceramics as well as sintering and debinding of metals or other materials. We manufacture our vacuum furnaces or inert gas furnaces as industrial furnaces or laboratory plants.

Applications Plant data Contact

Applications

Debinding ceramics & metals

Debinding removes the binders with their organic components from the green compact.

Ceramics & Metals Sintering

Sintering of ceramics and metals after debinding or shaping by means of additive manufacturing, pressing or casting.

Vacuum and process gas brazing

Brazing processes place high demands on the furnace technology in order to guarantee the surface quality of the components to be joined.

Heat treatment

Heat treatment can be used to set the final properties of the component and surface, such as hardness, strength or conductivity.

Hardening / Annealing

Hardening can be used to improve the mechanical resistance of metallic materials by selectively changing and transforming their microstructures.

Ageing

Both materials and components are subject to accelerated ageing at the beginning of their life cycle. This initial ageing can be simulated in retort furnaces..
