Investment casting – progressive foundry technology
Blažík, Petr ; Macků, Martin (referee) ; Mikulka, Vít (advisor)
The goal of this bachelor thesis is to bring special retrieval about possibilities of investment casting technology used for casting dimensional accurate products from aluminum alloys together with lost-wax process. The thesis deals with problems of the dimensional accuracy and the surface quality of casts produced by this technology. Further a thesis is focused on possibilities of increasing mechanical properties by the modification of casting procedure. At the end a thesis describes special technologies used for casting dimensional accurate aluminum alloys products used in aerospace industry, their principle and reachable mechanical properties.

Research plasticity of foundry sands
Macků, Martin ; Křístek, Jiří (referee) ; Rusín, Karel (advisor)
The subject of this thesis was to develop a comprehensive methodology for evaluating the plasticity of molding sand. This study was focused on four types of mixtures that are used in the foundry industry. For the evaluation of plasticity was important to provide an indicator of the deformation ability, calculation of deformation and logarithmic transformation for compression. Plasticity methodology was applied in this work only on the pressure effect. Studies of this issue can have a great influence on the production of correct forms due to the ability to withstand tension without breaking form.

An overview of advanced rapid prototyping techniques and their use in foundry industry
Drda, Jan ; Stachovec, Ivo (referee) ; Macků, Martin (advisor)
This bachelor thesis deals with overview of Rapid Prototyping techniques and their application at foundry industry. It’s split into three parts. In the first part is shown whole process that leads to prototype creation with rapid prototyping techniques. Second part shows overview of techniques which are used around the world. It’s split into three smaller parts that shows basic allocation between techniques and there are main specifications, advantages, disadvantages and application. The last part is summary of current situation in Czech Republic and there is practical example of application Rapid Prototyping techniques at manufacturing.
