Modern advanced production techniquesare fast moving into the realms of the fantastic, and micro metalpowder injection molding (micro-MIM) is one of them. With micro-MIM,it is possible to combine and shape different types of materialsuch as a biocompatible titanium stirrup, a replacementfor the small bone in the human ear.
Before injection-molding miniature parts, theresearchers mix the fine metal powder with an organic binding agent.The mixture can then be processed on an injection molding machine inthe same way as a plastic. Following this, the binding agent isexpelled from the component, which is then sintered to a high density.
