Extrusion Die
CED® Cartridge® Dies
Greater dimensional stability. High Productivity. Low Maintenance.
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 increase the extrusion speed due to lower friction and reduced exit temperatures. These features allow you to increase the productivity of the extrusion factory.

Extrusion Dies
Maximum processing speeds. Minimal test pressings with high reproducibility.
If you’re looking for ambitious aluminum profiles, you’ve come to the right place. This is where WEFA’s specialists really shine. Together with our international extrusion plant partners, we implement innovative die concepts - always taking the latest research in flow technology into consideration. The goals are clearly defined: achieving maximum extrusion speed, reducing the number of test pressings – and all at the highest levels of reproducibility. WEFA’s flat, porthole and tube dies are used for profile applications in mechanical engineering, construction and electrical engineering as well as in the automotive industry.
We achieve outstanding results using high-quality steels in combination with our excellent design know-how and modern precision manufacturing facilities.
Whether producing large flat dies with a diameter of up to 600 mm or tackling requests for the smallest tolerances and high-quality profile surfaces – WEFA provides technically and economically-convincing solutions in premium quality.
