The production method for metal parts with micro sized porous structure has been developed by applying "powder space-holder method" in metal powder injection molding process. In addition to metal powder and thermoplastic binders, coarse spherical material made of thermoplastic was used as lost material for formation of fine porous structures. The specimens were made by extrusion and injection moldings. The difference in these molding methods on the porous structure and those mechanical properties were investigated. It was shown that the porosity and strengths were controllable by changing the volume fraction of space holding particles. If was also demonstrated that the complicated shaped metal parts with micro porous structures can be produced using various kinds of metal powders by using metal injection or extrusion molding methods.
