Complex extruded profiles developed using metal injection moulding feedstock

October 9, 2007

The Fraunhofer IFAM Institute in Bremen, Germany, has developed a process for the manufacture of complex-shaped profiles by extruding metal injection moulding feedstock.

000416Research activities have been directed towards expanding the scope of applications for extruded products made from the wide range of feedstock materials currently available for the manufacturing of MIM components. Specific feedstock compositions have been developed along with extrusion process parameters and the appropriate control of the debinding and sintering stages.

The extrusion of MIM based feedstock is seen as a logical step in further developing this powder-based primary shaping technique. A major focus of IFAM’s research work has been on the cost-effective mass production of theoretically endless products.

Areas of application for extrusion of feedstock range from heat pipes manufactured from copper-based materials for heat transport and heat exchange to pipes with a controlled porosity for mass transfer applications. Geometries processed to-date include:

  • rods – including rods with circular inner holes
  • tubes
  • comb-like structures

Additionally IFAM is looking to expand the functionality of an extruded part by locally combining materials with different physical properties, for example dense and porous materials.
