Achieving perfection through close cooperation with research institutes and customers
WEFA develops and constructs extrusion dies with the help of 2D and 3D construction (design) technology taking the latest know-how in flow technology (viscosity) into account. This is a result of the company’s collaboration with renowned technical universities such as the ETH in Zurich and the TU Berlin. The research focus and main objective is, above all, flow simulation on the computer. In close cooperation with its customers, WEFA is continually improving its construction knowledge to produce tools that can be immediately implemented.
Best quality to meet strictest requirements
WEFA utilizes exclusively hot-forming steels according to DGM regulations. Special steels with high heat resistance and toughness are also used. Thus, even with critical tongue ratio, best results can be achieved.
Steel and coating analysis are carried out in our own metallographic labs. We can in this way quickly determine any potential causes of failure that could arise during the extrusion or nitriding process.
Dedicated employees, state of the art production facilities and computer-aided measurement systems
We use the most up-to-date production facilities for the production of our dies. Our highly-qualified and dedicated staff ensures a smooth production process. We create reproducible dies with tight tolerances and highest surface requirements using HSC lathes and mills, 3D CNC technology, controlled jig grinding machines as well as horizontal and vertical eroding machines with pallet changers. These high-precision dies are then inspected on measuring machines and delivered with the appropriate documentation.
Reliability through on-site coating plant
Consistent quality can only be ensured when the heat treatment, nitriding and coating are all done in-house. The heat treatment is adapted according to need and is carried out using vacuum furnaces. We utilize our own Chemical Vapor Deposition (CVD) coating plant to produce not only various coating chemistries, but also to develop new coatings – for example for alloys that are difficult to push.
Reliable and Certified
In 1995, WEFA instituted a quality management system for the development, production and distribution of coated and uncoated extrusion dies. This was applied in all areas of the company and is in compliance with EN ISO 9001:2008. It is binding for all employees and has been certified by TÜV. WEFA additionally instituted an environmental management system in 2006 and was certified by EMAS.
