ALD ModulTherm® heat treatment technology has been used successfully worldwide for many years and is the preferred method for the heat treatment of new transmissions and diesel injection systems in the automobile industry.
The ModulTherm® technology is especially suited for
- case hardening
in a temperature range up to 1250 °C.
Technology at a glance
Thermal and thermochemical heat treatment processes take place in individual treatment chambers which operate separately. Therefore, various processes can be performed simultaneously. A shuttle module, running on rails, serves the treatment chambers. The shuttle module contains a transport chamber and a high pressure gas quench chamber, combined in one unit.
The parts are hardened homogeneously and safely in this specially developed quench chamber, using gases such as nitrogen or helium under high pressure, of up to 20 bar, and a high velocity.
Hardness which pays off
The heat treatment system ALD ModulTherm® can be integrated into the mechanical production environment. There is no exposure of heat, exhaust gas or other harmful effects to the surrounding area of the plant. It is evident that the integration of heat treatment into production increases productivity. And the modular design of the ALD ModulTherm® heat treatment system allows tailoring the plants individually to meet the customer`s specific requirements exactly.
