Abstract
Metal Injection Molding (MIM) is known for high-volume production of small parts with fine tolerances. The final part geometry is the result of the process parameters of the entire production chain as well as a complex interplay of the feedstock binder system, the powder distribution within parts and the relative sizes and positions of design features.
The complexity creates a need for reworks during the tooling design phase, which can be both costly and time consuming. Freeform Injection Molding (FIM) allows a new approach, where 3D-printed, single-use molds can be used for easy, fast and inexpensive tooling design experimentation. This paper documents a generally applicable rapid tooling development methodology using FIM for MIM.
The method is validated by production of 17-4PH stainless steel MIM parts.
