Material - CosTherm

The diverse cosTherm product spectrum, consisting of thermosetting, mica and calcium silicate materials offers custom solutions that cater for:

  • High temperature stability

  • Very low thermal conductivity

  • High load changes

For additional applications, there are special solutions such as moulded mechanical engineering parts or coatings to reduce the chemical exposure of the components.

Sample Solutions


We produce a range of components and parts for glass manufacturing machines and glass blowing machines, such as bucks, cooling boards, stackers, transverse belts, grippers and levers.

Gripper fingers

Gripper fingers have component-specific contours at their ends that enable them to pick up, grip, transport or guide components. They are used primarily in electronics manufacturing.

Complex 3D components for thermal insulation

The manner in which these insulation materials are implemented can be as varied as the requirements placed on them: from a simple intermediate layer all the way to complex 3D components with various material combinations that are produced on a 5-axis…

Blank holders

Blank holders serve to hold components securely in position in the application. They are typically held against a surface/contour.

Heat insulation board

DOTHERM and ISOCOS offer heat protection plates that are precisely adapted to the respective process requirements in terms of material, compression strength, temperature resistance and dimensional stability.

Non-material-specific insulation solutions

In many industrial applications, it makes sense to use multi-layered materials or material combinations.
