Process Chain

WEFA stands for the highest quality. Customer satisfaction is our top priority. As a solution provider with customers all around the world, we provide the precision we promise. And we don’t stand still. Together with our cooperation partners, WEFA creates R&D solutions to always stay one step ahead of the competition. Our committed and highly-trained team of specialists goes out of their way to satisfy our customers’ needs. This is something we’re particularly proud of.

Development & Design

We aim for perfection, working closely together with research institutes and our customers

WEFA develops and designs top-of-the-line dies using 3D design technology and simulations based on the latest flow research findings. This arises from our research collaborations with top technical universities in three countries: the ETH Zurich, TU Berlin, Konstanz University of Applied Sciences, the TU Dortmund, University of Hannover, and Ohio University. We work closely together with our customers to continually refine our design expertise and produce dies that are immediately ready for operation.

Laboratories and Steels

Top quality for the highest standards

WEFA exclusively uses hot-work tool steels based on the DGM guidelines. We also use special steels with high thermal stability and toughness. These steels can handle critical loads and fulfil the highest requirements.

Steel and coating analyses are carried out in our on-site metallographic lab. This allows us to quickly determine any potential malfunctions that might occur during the extrusion and nitriding process.

Die Manufacturing

Committed employees, modern production facilities and computer-assisted metrology

At WEFA we manufacture dies using the most cutting-edge production facilities. Our committed and highly-trained specialists oversee a smooth-running production flow. We use HSC lathes and milling machines, 3/5 axis CNC technology, controlled jig grinding machines as well as wire and die sinking EDM with automatization to produce dies with the lowest tolerances and highest surface standards. These highly-precise dies are then tested on CMM measuring machines and delivered with the corresponding protocol.

Heat Treatment & CVD

Continuity thanks to our own coating facilities

WEFA ensures consistent quality by performing the heat treatment and coating process in house. The heat treatment is adjusted according to need and carried out on our vacuum heat treatment systems. We produce a range of layer systems on own chemical vapor deposition (CVD) coating facilities and continue to develop new layers – such as for difficult to extrude aluminum alloys and other challenging applications.

Quality Assurance & Sustainability

Binding and certified

WEFA’s quality management system for the production, purchasing, administration and sales of coated and uncoated extrusion dies and other die parts has been based on the DIN EN ISO 9001 for over 25 years. In addition, we have been using the EMAS and DIN EN ISO 14001 management system for our sustainability, energy management and work safety procedures.

Customer Service

Optimal support. Personal consultation. Comprehensive service.

Our committed and highly-trained specialists oversee a smooth-running production flow. They are able to quickly and precisely respond to our customers’ needs – because they understand the technology, can analyze the situation carefully, and have the necessary experience.
Our customers receive individualized and personal support. We regularly offer workshops on die technology either in our own or an external training center. Our customers benefit from our correction and extrusion experience. We offer long-term support for all questions and needs and always look forward to helping you!
