CVD-coated extrusion dies
WEFA
Precision extrusion dies for complex profiles, thin walls and tight tolerances—with advanced CVD coating for longer die life, consistent profile quality and reduced maintenance by eliminating the nitriding process altogether.
Overview
Precision that lasts beyond the first run.
WEFA’s CVD-coated extrusion dies protect critical bearing surfaces against wear, helping maintain dimensional stability and consistent profile quality throughout longer production campaigns.
Lower friction can support higher extrusion speeds and reduced profile exit temperatures, with no corrections or nitriding cycles.
Designed around your profile geometry, alloy, press capacity and container diameter, WEFA dies serve demanding applications across the automotive, aerospace, aviation, electronics and solar industries.
Key benefits
Engineered for demanding profiles.
The features below are the ones that change how the equipment behaves on the floor, not the ones that fill a brochure.
- Complex profile geometries
- Advanced die designs for multi-hollow, asymmetric and technically challenging aluminium profiles.
- Thin walls and tight tolerances
- High dimensional stability for profiles requiring thin sections, small features and precise tolerances.
- Longer die life
- CVD-coated bearing surfaces resist wear, helping extend productive die life and reduce maintenance interruptions.
- Consistent profile quality
- Stable die geometry supports repeatable dimensions and surface quality across extended production campaigns.
- Higher productivity potential
- Reduced friction and lower profile exit temperatures can enable higher extrusion speeds, depending on the alloy, profile geometry and press conditions.
- Reduced die maintenance
- Coated bearing channels require fewer corrections and eliminate routine nitriding and repolishing, reducing downtime between production runs.
