Dewaxing and Pre-Sintering Furnaces

Our hot wall retort furnaces with multi-zone heating up to 1100°C are ideal heat treatment systems for a wide range of processes that require an inert gas or reactive atmosphere.

Because of the gas-tight working space, processes in slight overpressure, but also in vacuum up to a maximum of 650°C, are possible. Special safety technology also allows the furnace system to be operated under reactive gases such as hydrogen.

Our systems are particularly suitable for dewaxing and pre-sintering of powder metal parts, for soldering , joining processes and other heat treatments of a wide range of materials. All basic systems can be equipped with a wide variety of options to suit perfectcly to your application.

Vacuum- & Sintering Furnaces

Our cold wall furnaces / cold wall retort furnaces with multi-zone heating - up to 2400°C enable you to realize technically demanding heat treatment processes.

The furnace retort enables processes under inert gas and reactive gas atmospheres or in a vacuum of up to 10-5 mbar - depending on the type of furnace. Systems with residual debinding device also possible.

Choose from various system options and configure your furnace to exactly suit to your process. We would be there to help you with the design and features.

Our vacuum/sintering furnaces are available in the following versions:

Retort – Heating– Insulation made of graphite

• For processes under a inert gas / reactive gas atmosphere or in a vacuum
• Max. temperature up to  2200°C  (special version up to 2400°C ) possible
• Vacuum up to max. 10^-4 mbar

Retort-Heating - Insulation made of molybdenum

• For processes under a inert gas / reactive gas atmosphere or in a (high) vacuum
• Low-carbon atmospheres
• Max. temperature up to 1600°C  (special versions up to 2400°C ) possible
• Vacuum up to max. 10^-5 mbar

Pressure Sintering Furnaces up to 100 bar

For the highest demands and quality of your parts.

Combine two processes in one furnace system: vacuum sintering and isostatic compaction.

Our pressure sintering furnaces are available in 2 different standard pressure levels – 60 bar and 100 bar.

Optionally, the high-pressure furnace can also be equipped with a dewaxing system to create an all-in-one system. The expelled pressing aids / binders are condensed and collected in a binder trap. A multi-zone graphite heater, a retort and a special insulation design ensure very good temperature homogeneity and reduce operating costs.

An effective rapid cooling device reduces production times to a minimum.

When dealing with high pressure and reactive gases, we rely on the latest control and safety technology. Our pressure sintering systems are certified according to the pressure equipment guidelines. All safety-relevant functions are tested and approved by TÜV /specialized authority .

MIM-Sintering Furnace

TISOMA MIM sintering furnaces stand for the highest quality durability. Our compact systems come on a machine platform for quick commissioning on site.

A multi-zone molybdenum heater ensures the best temperature uniformity up to a maximum of 1600°C for demanding processes in various gas atmospheres and in vacuum up to 10^-2 mbar.

The integrated residual debinding system with binder trap and flaring off system prepares your parts for the sintering process in the best possible way.

Our systems can be individually configured to suit to your needs, including a high vacuum option up to 10^-5 mbar. State-of-the-art control technology and our in-house system visualization smoothly integrate the MIM sintering furnaces into your production landscape.

The furnace usable space is available as a slide-in system for sintering trays / plates or as a retort box for your individual, free loading.

our standard sizes:

(individual sizes, grid dimensions according to existing sinter plates on request, up to a maximum length of 1500 mm)

Continuous Furnace Systems

Continuous furnace systems are used for continuous processes with fixed process times and large throughputs.

This type of oven system is very individually adapted to the customer process.
YOUR individual furnace system is planned and designed based on the required throughput, the desired cycle times and other process technology requirements.

Our continuous furnaces meet the highest technical requirements:

Temperatures up to 2200°C

• Debinding, sintering and other heat treatments
• Different gas atmospheres, change between debinding and sintering furnace part possible
• Flaring off system as a gas fired ring burner or thermal combustion system
• Drive systems, depending on the version: push-through technology, roller, chain feed
• Available as an automated system with a magazine or as a circulation system upon request
