| Abstract: | The influence of some important injection processing parameters,including temperature,pressure and mold temperature,on the injection defects in compacts has been studied using metal injection molding (MIM) standard tensile specimens.Some optimum injection parameters have been obtained. The forming mechanism of the defects such as short shots,fracture,and central through-hollow is discussed. |
