Abstract
A novel production method for porous metal components has been developed by
applying powder space holder (PSH) method to metal powder injection molding (MIM) process.
The PSH-MIM method has an industrial competitive advantage that is capable of net-shape
manufacturing the micro-sized porous metal products with complicated shapes and controlled
porosity and pore size. In this study, the small impeller with homogeneous micro-porous structure
was manufactured by the PSH-MIM method using porous compounds composed of fine stainless
steel 316L powder and polymethylmethacrylate (PMMA) particle. The effects of combinations in
size and fraction of PMMA particle on dimensional tolerance and variation of sintered porous
specimens were investigated. It was concluded that the PSH-MIM method could manufacture
commercially micro-porous metal components with high dimensional accuracy.
