Graphite Materials provides quick and straightforward assistance and gets your vacuum, inert-gas and sintering furnace up and running again. Generally within eight days. As practical experts, we know what really matters to you: Reliable furnaces that work efficiently. So we only use high-quality, tested materials to line your heating chamber. For example, insulation with high thermal insulation, moisture-repellent for short pumping times. This increases the efficiency of your heating chamber, so ensuring a long service life. On request, our comprehensive service also includes collecting your heating chamber and returning it to you after servicing. Of course, we will also be happy to support you on site with commissioning.

Our maintenance services:

  • Collection/delivery of the heating chamber
  • Dismantling of the old insulation
  • Disposal of the old insulation and other defective parts
  • Cleaning of the heating chamber
  • Repairs to the cage and add-on parts (adjustment, welding, etc.)
  • Reconstruction of the heating chamber lining
  • Application of surface protection (CFC, graphite foil, graphite coating)
  • Installation of edge protection (U-profiles made of CFC)
  • Replacement of worn parts (ceramics, molybdenum, etc.)
  • Assembly of various add-on parts (current bridges, heating rods, connector pins, batch carriers, etc.)
  • Mounting of third-party components
  • Adjustment of door and cooling flaps
  • Partial disaster recovery

Optimization and engineering for excellent

With Graphite Materials, you increase the service life and energy efficiency of your industrial furnace. You cut operating costs in the long-term and reduce the risk of production losses and harmful emissions. Important influencing factors include the insulation of the heating chamber, as well as the design of the heating system.


Graphite Materials advises you on installing the insulation, as well as on the materials used and finds customized solutions for your applications. We test and document, for example, the resistance of the heating elements manufactured by us. On the basis of these results, we achieve constant temperatures and an optimum energy flow in your industrial furnace. To continue to optimize our engineering services, we work on scientific projects in close collaboration with universities and research institutes. Graphite Materials is your competent partner.

Our optimization and engineering services:

  • Technical consultation for carbon-fiber furnace insulation (focusing on: energy efficiency and service life)
  • Assessment of reactions in production processes between carbon/graphite and other materials
  • Design and production of graphite and CFC heating systems in accordance with mechanical and thermal requirements
  • FEM simulation and calculation for mechanical and thermal load cases
