Possibilities of using modern methods in manufacturing of prototype castings focused to combination of RP and investment casting
Sysel, Karel ; Kosour, Vojtěch (referee) ; Horáček, Milan (advisor)
The objective of this thesis is to close the possibilities of modern foundry industry and demonstrate that nowadays it isn’t only about production of inaccurate casts, which were products of a lengthy industrial processes and testing of the new casting moulds. So that the thesis is concentrate on possibilities of the Rapid Prototyping Technologies and investment casting, because especially combination of them gets a new possibilities and direction to the modern foundry industry.
Additive technologies and their using when making prototype castings
Čagánek, Radim ; Horenský, Jiří (referee) ; Horáček, Milan (advisor)
This bachelor´s thesis deals with Rapid Prototyping systems and their uses in foundry. This thesis describes three most significant RP systems, on which is explained principle and distribution of them. The another part of the thesis describes how is RP systems useful in production of sand molds, ceramic shells and permanent mold.
Possibilities of using modern methods in manufacturing of prototype castings
Novák, Luboš ; Cupák, Petr (referee) ; Horáček, Milan (advisor)
Rapid prototyping is a set of technologies applicable to the production and development of prototype castings. It is a means for accelerating and cheaper prototyping, or for the preparation of small series production of castings. The thesis is focused on some of these production processes and technologies.
Optimation of wax pattern manufacture - wax mixtures and its testing
Koběrský, František ; Kosour, Vojtěch (referee) ; Horáček, Milan (advisor)
The bachelor’s thesis deals with a general description and distribution of waxes and wax mixtures for investment casting in the first part. The second part is devoted to descriptions of various mechanical and physical properties of waxes and their testing.
Application of rapid prototyping in foundry industry
Krejčí, Zbyněk ; Macků, Martin (referee) ; Kosour, Vojtěch (advisor)
These bachelor thesis deals with the practical aplication of rapid prototyping at foundry industry. In the first part of the thesis is given list of the most important methods of rapid prototyping, those principles, advantages and disadvantages. And the second part is dealing with aplication of these methods at foundry industry, and its evaluation.
Production of real component by lost wax casting technology
Remeš, David ; Kolář, Ladislav (referee) ; Jaroš, Aleš (advisor)
This thesis deals with the real production of component by using investment casting technology. The thesis describes characteristics of investment casting technology, subsequently construction of 3D component, production of silicone mould, production of wax (plastic) of the model component. At the end of the work is provided technical and economic evaluation.
Trends in manufacturing of non-permanent wax patterns in investment casting technology
Halaška, Jan ; Šmatelka, Jakub (referee) ; Horáček, Milan (advisor)
Bachelor’s thesis describes the most used wax blends and equipment for manufactory of sophisticated castings. The thesis includes two major sections and these are wax blends and wax patterns. The aim of this thesis is to develop a literary review focused on the most advanced equipment and raw materials used in the investment casting technology with a focus on the manufactory of wax pattern.
"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.
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.
