Metal Injection Molding - A Review
Subscribe/Renew Journal
Metal Injection Molding (MIM) is relatively a new technology for producing metal components of complex geometry. MIM is an extension of powder metallurgy process. Various products of metals and its alloys including difficult-to-machine materials such as titanium, tungsten etc., can be effectively manufactured by MIM process. MIM process comprises of four steps; mixing of metal powders with binders, injection molding of coated-metal powders to produce green parts, de-binding to separate binders from green part and the final stage is sintering. The process parameters in mixing, injection molding, de-binding and sintering play a vital role in the quality of final product.
This paper is aimed at reviewing the MIM process parameters and materials.
