Abstract:A new wax-oil-polyethylene binder was developed for Fe-2Ni powder injection molding. The advantages of both wax-based and oil-based binders were acquired. Moreover, the debinding solvent could be recycled. The miscibility of the binder ingredients and the characteristics were evaluated. The results show that the maximum powder loading can reach 60%(volume fraction), and the two-direction debinding rate is over 2 mm/h. The drying time for 6.37 mm thick samples is less than 20 min. The recycle ratio of the debinding solvent is over 95%.
Key words: metal injection molding; binders; solvents
