Over the decades we have refined the manufacture of ceramic insulators to perfection. Highly sophisticated monitored processes form the basis of a production system in which small customized product runs are implemented with the same precision and reliability as standard volume parts. Our improvement management system ensures an ongoing refinement of all processes and continuous advancement in cost efficiency.

Selected ingredients of high purity and homogeneous properties are weighed, mixed to formula specifications, and subjected to a grinding process. Vacuum extrusion presses form the plastic filter cake into cylindrical blanks ("body") which are subjected to a closely controlled drying process to condition them for the following shaping steps.

Vertical lathes are used to machine the blank to its desired contour. After a further precision drying stage the unfinished insulator already possesses a high strength due to the clay bond and is ready for the application of the glazing by an immersion process. The subsequent firing stage creates the very hard ceramic structure.

The insulating body is now equipped with its metal hardware to complete the production process. It is then tested to international standards or customer specifications.
