Effect of Thermal Debinding Conditions on the Sintered Density of Low-Pressure Powder Injection Molded Iron Parts

Low-pressure powder injection molding (LPIM) is a cost-effective technology for producing intricate small metal parts at high, medium, and low production volumes in applications which, to date, have involved ceramics or spherical powders. Since the use of irregular powders represents promising way reduce overall costs, this study aims investigate potential manufacturing molded from commercial iron using LPIM approach. To end, viscosity feedstock was injected into rectangular mold cavity, thermally wick-debound three different pre-sintering temperatures, finally sintered an identical sintering cycle. During debinding, increase temperature 600 850 °C decreased number fine particles. This density 6.2 5.1 g/cm3, increased average pore size 9 14 ?m, circularity 67 59%.
