Abstract

The micropowder injection molding process (microPIM) offers a large-scale fabrication technology for metal/ceramic microstructures. Current R + D efforts focus on increasing the degree of complexity of the 3D microparts molded rendering it necessary to implement novel tools and demolding methods. The increase in the degree of complexity was demonstrated by a dispenser screw. Progress included the adaptation of the untwisting technique known from plastic injection molding to PIM green compacts. This allowed for a burr-free demolding in spite of the backcuts of the screw design.
