Metal injection moulding (MIM) process consists of injection moulding, debinding, and sintering process using feedstock containing thermoplastic binder and metal powder. Precision casting and machining are very difficult to apply to make turbocharger vanes because of complex shape and small size of the vane. Recently, a manufacturing method using the latest MIM process has attracted considerable attention. Turbocharger vane is made using stainless steel HK-30 because of its high corrosion resistance at high temperature. MIM process is effective for making precision metal parts. Further, a filling analysis using computer simulation reveals that an injection moulding process (MIM process) directly influences the material property, filling time, filling pressure and shear rate, etc. In this study, we analyze the metal injection moulding process for turbocharger vanes using commercial CAE program Moldflow to obtain baseline data about mold design and determine the optimum conditions of injection moulding, such as pressure and injection time.
