Extrusion across the process chain
Simulation
Modelling processes and profiles
Simulating the process, profile properties and applications more accurately.
The simulation of the extrusion process and of the properties and applications of extruded profiles is a central topic of the committee’s work.
Products and applications
Rods, wires, tubes and profiles
Discussing the properties and applications of extruded products.
Extrusion is used to manufacture rods, wires, tubes and profiles. Applications in lightweight construction are also part of the technical context.
Exchange between industry and research
In the Expert Committee, extrusion plants and supplier companies meet universities and research institutes. Industrial members represent production, quality assurance, product and process development, and mechanical, plant and tool engineering.
Some of the universities and research institutes can conduct research on their own extrusion lines. This brings practical industrial experience together with scientific questions relating to extrusion and new applications.
Benchmarks and research projects
Benchmarks
Energy and die service life
Comparing specific energy consumption and die service life.
Benchmarks compare, among other factors, specific energy consumption and die service life. They support extrusion plants in aligning with the current state of the art.
Research projects
Practice-relevant objectives
Discussing the objectives and results of research applications.
For research applications, the Expert Committee supports applicants in setting practice-relevant objectives and discussing the results.
Working groups
Connecting the exchange of experience
Bringing together Research, Light Metal and Heavy Metal.
The exchange of experience connects the Working Groups Research, Light Metal and Heavy Metal.
In extrusion, metals such as aluminium or copper and their alloys are pressed through a shaping die. This produces rods, wires, tubes and profiles. Extruded profiles are used in the automotive sector. In electrical and mechanical engineering, they are used, for example, as finned heat sinks or support profiles; in medical technology, they are also used in applications involving bioresorbable materials.
The interaction of materials development and tooling technology is decisive for implementing new applications. A further technical focus is the more accurate simulation of the extrusion process and the properties of the resulting products. Progress in describing actual friction conditions in the forming zone expands the possibilities for product development.
