Today, microinjection moulding represents an established special variant among the different replication techniques strongly promoted by the growing market demand for microcomponents. Spearheading progress towards more sophisticated technologies, micro powder injection moulding offers a large scale fabrication process for metal/ceramic microparts. Minimal details in the range of 10 μm and replication accuracy down to ±0·3% (in special cases, ±0·1%) can be reached. With a twofold aim of reducing mounting costs and enabling the production of highly integrated devices two-component microinjection moulding is under development. Interesting examples are immovable or movable ceramic shaft wheel components.
