Because of the excellent performance of ductile irons and the unique superiority of investment casting, thepreparation of complicated and thin-wall ductile iron castings by investment casting shows a good developmentprospect. In this present work, combined with the actual product experiments, the characteristics of shell making,spheroidization, inoculation and defect prevention are presented, and some suggestions are given for investmentcasting of ductile iron.
