Technical micro parts are negatively affected by the flow and cooling conditions experienced during injection molding in comparison to macro parts. With the cooling dependent low degree of crystallization in the core and the high flow dependent component in the boundary layers combined with the high levels of orientation there is a high degree of inhomogeneity across the part and thus sub-optimal conditions for the in-service properties in general. An option for optimizing micro parts is processing using low thermal conductive mold inserts, which also leads to a reduced cooling rate. By manufacturing with inserts made from zirconium oxide with a thermal conductivity of 2 W/mK similar property values to variothermal process control can be achieved. The results show that materials with high rates of crystallization and high crystallization potential have beneficial effects on the properties of micro parts. However, possible flow dependent property anisotropy also has to be considered.
