With miniaturization of products with more complex functions integrated, micro-parts have played an ever-increasingly important role in our daily life. This paper presents new developments in micro-injection molding and hot embossing, the two most viable processes for the production of micro-parts. Hot embossing can be used to create the necessary micro-structures not only on polymeric parts, but also on an aluminum alloy mold with controlled quality. A new mechanism of micro-forming, namely the plastic deformation of the polycrystalline AA 6061 grains near the material solidus temperature was reported. It was thus demonstrated that grain size is not the limiting factor on the minimum feature size that could be produced for a polycrystalline material. In the micro-injection molding technique, two main factors, namely melt compressibility and mold surface roughness, were studied. Melt compressibility can be neglected for simplicity in the simulation of macro-injection molding but should be considered in micro-injection mold-filling. Mold surface roughness also has effects on the flow in micro-cavity during the filling stage.
