"Net Shape" technologies suitable for castings
Bartoš, Filip ; Zemčík, Ladislav (referee) ; Horáček, Milan (advisor)
This thesis has the task to gather basic information about the technologies used in the manufacture of finished castings, i.e. without further processing, the so-called "Net-Shape". It is focused on technology investment pattern, the combustible model shell casting "Croning“, die casting pressure, die casting to ingot and centrifugal casting. All these technologies are compared in terms of specific features, range use, production economy, the advantages, disadvantages, the resulting quality of castings and other important factors.

Optimation of manufacturing technology of high value castings
Šmíd, Dušan ; Vašťák, Patrik (referee) ; Horáček, Milan (advisor)
The main target of this thesis is to choose the suitable hard filled wax for the invest-ment casting foundry Fimes a.s. There are several suppliers of these waxes in the World and in this work waxes of the most reputable suppliers from Europe have been investigated. During these tests there were mainly technological properties of the waxes and also dimensions of both wax patterns and also the final castings measu-red. Suitability of the tested waxes, their technological characteristics, analysis of di-mensions and finally basic economical calculations have been then used in this the-sis as a tool for the recommendation for the most suitable wax for the Fimes foundry.

Using "reverse engineering" approach when making replica of Al casting by lost wax technology
Bezděk, Adam ; Cileček, Jarmil (referee) ; Horáček, Milan (advisor)
The aim of this thesis was to produce a prototype casting of aluminum alloy with usage of reverse engineering technology. In a production process surface quality and dimensional accuracy was optimized. 3D scanning, FDM technology, ABSplus surface finishing possibilities and investment casting technology is introduced in theoretical part of this thesis. Practical part of the thesis includes description of original parts, their 3D scanning, usage of RE and RP, production of new castings and evaluation of their dimensional accuracy and surface roughness.

Present state of investment casting technology
Bártů, Zbyněk ; Horenský, Jiří (referee) ; Horáček, Milan (advisor)
.The bachelor’s thesis is focused on the most modern and latest trends used in investment casting technology. The aim of this bachelor thesis is literary research on the most modern equipment that used wax pattern manufacture, ceramic shell manufacture, de-waxing, metal pouring and finishing operation. The first part describes the history and development of the investment casting technology. The following chapters disclose a general procedure for the production of the investment casting technology and equipment suitable for its manufacture.

Present state of investment casting technology
Soukupová, Lucie ; Šmíd, Dušan (referee) ; Horáček, Milan (advisor)
The Bachelor’s thesis deals with the latest trends in investment casting technology, from wax pattern manufacture, ceramic shell manufacture, de-waxing, shell heat treatment up to metal pouring and finishing operation. In the first part, the outline of the world production and the usage of investment castings nowadays are introduced. The other parts of the project include the basic technique of using new technologies. The aim of this work is developing a literature search focused on the most modern equipment and raw materials that are used in investment casting technology and testing of wax mixtures and ceramic slurries.

Rapid prototyping methods (RP) suitable for foundry technology
Slovák, Vojtěch ; Helán, Jiří (referee) ; Horáček, Milan (advisor)
The aim of this thesis is to make an integrated view of the most considerable current Rapid prototyping methods and the most frequent applications in the foundry industry. The work does not propose to find all existing Rapid prototyping methods and their use in the foundry technology either. But it wants to take down the most important aplications of Rapid prototyping methods especially direct casting methods.
