Coated Extrusion Dies (CED®)
Better Dimensional Stability. Less Maintenance. High Productivity.
WEFA’s coated extrusion dies have superior durability because the bearing channel is protected from wear and tear. With our own patented coating technology, we have achieved high-level form and dimensional stability for the pressed profiles. The dies are nearly maintenance-free due to the fact that no nitriding and repolishing is required. Without the need for nitriding cycles in coated dies, the extrusion process can be carried out with fewer interruptions. In addition, it is possible to work at higher press speeds because of minimal friction and reduced exit temperatures. Thanks to these qualities, the productivity of the extrusion factory can be increased.
