Abstract
This paper presents an innovative ceramic mould manufacturing technology aimed at improving the driftability of particularly difficult castings, which are characterised by complex geometry and a high tendency to bake/clog the mass in critical areas of the mould (holes, closed casting spaces, corners, sharp edges, variable cross-sections). Traditional ceramic moulds, despite their strength, often create problems during the casting knockout process, leading to casting damage and increased cleaning costs. The new technology is based on the use of a hybrid mould structure, the essence of which is the production of layers in the ceramic mould, in the central zone of the mould, characterised by a significantly reduced final strength, achieved after firing. These layers are made on the basis of an organic binder. As a result, excellent driftability of the castings and effective separation of ceramic residues from the surface of the castings is achieved due to the embedded layer. The special layers can be incorporated over the entire surface or only in the areas where fusion of the casting surface with the ceramic mass occurs. Tests conducted have shown that the developed technology significantly improves the driftability of ceramic moulds, especially for castings with complex geometries, where traditional methods fail. The introduction of this innovation has the potential to be widely applied in various industries where the requirements for precision and quality of castings are very high, such as the aerospace, energy and automotive industries.
