Ceramic moulded parts are increasingly being used in advanced components and devices due to their unprecedented material and performance attributes. The surface finish, replication quality and material shrinkage are of immense importance for moulded ceramic parts intended for precision applications. The current paper presents a thorough investigation on the process of ceramic moulding where it systematically characterizes the surface replication and shrinkage behaviours of precision moulded ceramic components. The test parts are moulded from Catamold TZP-A which is Y2O3-stabilised ZrO2 having widespread uses in the advanced industrial applications. The influence of the sintering process on the achievable roughness and replication differences between the mould surface and the final parts are discussed based on the experimental findings. Moreover, an investigation on the morphology and porosity distribution for the moulded ceramic parts is presented.
