Metal Injection Molding (MIM) technique allows for the production of highly porous metallic foams with porosity levels up to 90%. It makes use of the pressure built up by the decomposition of a foaming agent which is incorporated in a foamable precursor copper material obtained by powder compaction. Rheological is one of the key factors to ensure the successful of MIM technique and to predict failure,...
Copper foam has recently being applied to replace aluminium as heat sink. In this study, copper foam was manufactured via metal injection molding technique. Copper feedstock were prepared comprising 0wt.%, 30wt.% and 40wt.% of potassium carbonate into copper powder to produce open pore cell structure, which also mixed together with a binder system consisting palm stearin (PS), polyethylene (PE) and...
