摘要

Metal Injection Molding (MIM) is a net-shape process for producing metal parts that combines the design freedom of plastic injection molding with material strength near that of wrought metal. IHI has been developing the MIM process for low-cost manufacture of high pressure compressor vanes which are used in aircraft gasturbine engines. Material tests have been carried out on the vanes and the test results show good performance. Measurement of the dimensional precision of the prototype compressor vane has shown promising results. This paper describes the status of MIM process development at IHI.
