Metal powder injection molding is a new near-net-shape powder metallurgy technology derived from plastic injection molding. The core and key of this technology is the binder. The roles and characteristics of the binders and the advantages and disadvantages of various binder systems are discussed. The research progress of binders and degreasing are reviewed. Some problems in the research and development of the binders are pointed out.
