In industrial heat treatment, precision, reliability and durability are key factors for efficient processes. The stability of the electrical connections plays a decisive role, particularly in high-temperature systems in which hard metal tools, gear wheels, shafts, high-performance ceramics or semiconductors are treated.
Share case study:
In heat treatment plants, components are treated under extreme conditions, often at temperatures of over 1000 °C. The use of electrical energy as a heat source enables precise control of the process parameters, but at the same time requires components that can withstand long-term thermal and mechanical loads.
In addition to high energy consumption and costs for raw materials, the longevity of the system components is a key challenge. Connections and connecting elements must function reliably in order to avoid expensive downtimes and maintenance work.

Result:
The client from the maintenance sector was faced with recurring problems in the operation of its high-temperature systems:
The connection solutions used to date did not optimally meet the requirements for current carrying capacity and heat distribution.
The aim was to develop connections that could withstand the thermal and electrical loads and at the same time guarantee a long service life. Graphite Materials took over the engineering and developed a customized connection solution based on detailed process analyses:
A stable thermal balance was achieved thanks to the adapted design of the connections. Overheating in the connection area no longer occurs and adjacent components remain thermally relieved. The new design thus ensures a significantly longer service life.
