Technical Ceramics
Zurück
Wherever textile threads, wires, fibers or ropes are being drawn, guided or directed during industrial processes, wear parts made from technical ceramics have proven their superiority. Extreme wear resistance coupled with high resistance against most acids and temperatures as well as light weight and ease of shaping the material in its compacted state have made metal oxide ceramics an ideal material for these components. Even so these properties are shared by almost all technical ceramics, some materials are better suited for specific applications.
As a result, aluminum oxide ceramics are most common for thread and wire guides as well as guide pulleys and sheaves whereas for wet wire drawing purposes mostly zirconium oxide ceramics are used as capstans or drawing cones.
The manufacturing process can create more differences between components as the final quality of a part is widely influenced by the purity of ceramic materials and the pressure that is applied during the compacting process. In many cases diamond polishing of working surfaces is necessary to further improve the quality and longevity of a ceramic part.
The sheer number of alternatives makes it difficult for end users and purchasing agents to pick the most economic solution from available offers. As specialist for wear parts WireTrex can provide a wide selection of qualities and attractive pricing. The company also offers customers assistance to find the right solution for their application.
In addition to new parts sales WireTrex specialises in reconditioning of ceramic drawing tools. After grooves have been removed and the parts have been diamond polished to a high shine, these “almost” new parts are ready for years of quality service.
