Influence of raw materials to the final quality of aluminium investment castings
Macko, Martin ; Vašťák, Patrik (referee) ; Horáček, Milan (advisor)
The purpose of this thesis is to assess the current state of production of ceramic shells in MESIT Foundry, a.s. and optimize it. The shells are evaluated in terms of their bending strength, gas permeability and microstructure. Subsequently, castings produced using the shells are evaluated with regard to number of non-conforming products and presence of defects. The final part seeks to compare different shells and outlines a possible new approach to the development of ceramic shells.
