Process Combination of Combined Deep Drawing and Cold Forging

Funding: German Research Foundation (DFG)
Project: TE 508/61-1
Contact: Oliver Napierala M. Sc.

The combination of different materials represents a possibility to adjust the local mechanical properties of a component and to reduce the weight by a suitable choice of materials.

Prevention of Longitudinal Weld Streak Defects on Anodized Aluminum Profiles

Funding: AiF/Stifterverband Metalle
Project: 18756 N
Contact: Johannes Gebhard M. Sc.

Anodized profiles are widely used as visual components. A common defect is the occurrence of longitudinal weld streaks on the surface, which depend on the whole process chain from casting of the billets to anodization of the extruded profiles.

Analysis and Extension of the Limits of Application in Metal Forming-Based Recycling of Aluminum Chips

Funding: German Research Foundation (DFG)
Project: TE 508/60-1
Contact: Felix Kolpak M. Sc.
Status: Completed

In collaboration with the WPT (TU Dortmund University) the direct hot extrusion of aluminium chips was investigated.

Production of Aluminum Profiles with Continuous Reinforcement

Funding: AiF/Stifterverband Metalle
Project: 18959 N/1
Contact: André Schulze M. Sc.
Status: Completed

In this project the composite extrusion process was investigated for industrial applications.

Composite Cold Forging of Cold Forged Semi-Finished Parts

Funding: German Research Foundation (DFG)
Project: TE 508/54-1
Contact: Christoph Dahnke M. Sc.
Status: Completed

For the manufacturing of composite shafts hybrid raw parts have been processed by forward rod extrusion at room temperature.

Influencing the Evolution of Damage in Cold Extrusion

Funding: German Research Foundation (DFG)
Project: CRC/TRR188 • Subproject A02
Contact: Oliver Hering M. Sc.

The properties of cold forged components are a consequence of residual stresses, strain hardening, and the resulting damage along the process chain.

Extended Technological Limits of Bulk Forming Processes in Different Temperature Ranges

Funding AiF/Fosta
Project 18229 N/P1058
Contact Oliver Napierala M.Sc.
Status Completed

The target of this subproject of the research initiative “Massiver Leichtbau” (massive lightweight construction) was the production of gear shafts with optimized surface properties by cold forging.

Prediction of Local Product Properties in FEM Forming Simulations

Funding AiF/Fosta
Project 18225 N/P1057
Contact Felix Kolpak M. Sc.
Status: Completed

The goal of this subproject of the research project “Massiver Leichtbau” (massive lightweight construction) was the exact prediction of an exemplary process chain regarding the resulting local product properties of the produced parts.

Manufacture by Forming and Characterization of Actuator Profiles Based on Shape-Memory-Alloys

Funding German Research Foundation (DFG)
Project TE 508/45-2
Contact Christoph Dahnke M. Sc.

Shape memory alloy wires can be continuously embedded in aluminum or magnesium profiles by means of composite extrusion. Due to the extraordinary properties of the NiTi wires, such as the shape memory effect and superelasticity, improvements of the mechanical properties of the composite can be achieved.
