Metal injection molding technology is commonly used in production of small and very complex parts. Residual porosity isunavoidable characteristic of P/M parts, affecting their final properties. During injection molding phase powder-binderseparation can occur, causing green density variation through cross section of the part. This behaviour is particularlypronounced as complexity of the parts increases. As a consequence, zones with different density and residual porosity canbe seen after sintering. In this regard, porosity and hardness distribution of the sintered ring-shaped part is analysed andpresented in the paper.
