Optimizing the ceramic tree mould taking into account the robotic shelling system
Petřík, Michal ; Šmatelka, František (referee) ; Horáček, Milan (advisor)
This diploma thesis deals with the optimization of the design pattern assembly for robot shell making system. Six types of castings were selected for optimization in regard to increase the utilization of liquid metal. The individual castings are described in the chapters and in the subchapters are described the original design pattern assembly intended for manual shell making, the designed pattern assembly shell making system with subsequent evaluation for the use of molten metal yield. The following chapters described the benefits of changing the pattern assembly design, the defects caused by this change and recommendations that should rule out the possible occurrence of these defects. The last chapter deals with a modified plate weight test, which was created directly for the conditions of the company Alucast s.r.o., where the practical part was solved.

Optimization of gating systems (their yield) in Al castings made by investment casting technology
Žižka, Jiří ; Šmatelka, František (referee) ; Horáček, Milan (advisor)
This diploma thesis deals with the optimization of gating systems of shape-complex aluminum castings produced by investment casting process. Two castings whose massive gating systems make problem with the use of liquid metal (so called yield) were chosen for optimization. Each casting is described in its own chapter. The individual subchapters deal with description of the original and newly designed gating system. Simulation, test castings, X-ray inspection and metallographic examination were performed for each variant. At the end of each chapter there is an evaluation of the results of the optimization of gating system.
