Proposition of casting technology of aluminium manifolds cast by tilt method
Spáčil, Ivo ; Kaňa, Václav (referee) ; Roučka, Jaromír (advisor)
Description of the theoretical factors for casting into metal molds. For thin-walled castings it has turned out that the most advantageous method is tilt casting. Tilt casting reduces the turbulence of the melt and reaches a directed solidification. Two molds were tested and measured for the experiment. During measuring the temperature regime was established lower temperature of the pouring basin than the other parts of the mold, which could cause a many of defects. The verification of mold technology has been performed. To achieve the accuracy of the casting, it is necessary to respect the different shrinkage according to the shape of the casting.

Production of the mold plunger
Rosa, Jakub ; Chladil, Josef (referee) ; Osička, Karel (advisor)
The meaning of the diploma thesis is to create a new mold plunger for injection mold using a suitable method according to the original mold plunger. The final mold part should meet the required surface parameters. The work is focused on the analysis of the original mold plunger and the experimental verification of suitable methods of production of the equivalent mold plunger.

Production technology for plastic socket outlet
Pokorný, Martin ; Orel, Daniel (referee) ; Kandus, Bohumil (advisor)
This project concentrates on the technology of manufacturing of the plastic socket outlet. It consists of two parts, where the first part is a literature study. Here are described the characteristics of the materials and their specifications. Further on is described basic knowledges technical methods of injection and some other technologies. The second section consists of the right proposal of the material. Further on in this section is described technological treatment. Mechanical function and its design and technical drawing are a part of this second section. As a final result is a brief comparison of the technology between the injection or pressing into molds. Herewith is also included a simplified financial budget calculation.

The design and technology of a mold production for the precision casting
Kopcík, Daniel ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
The theoretical part of this bachelor´s thesis describes basic attributes of the lost wax casting method. The aforementioned section describes casting stages from component assignment to model casting, with the main concern of making wax model moulds, materials employed for moulding mixtures and casting accuracy achieved by precise casting. The experimental part begins with mould design for two components set by a customer, continues with focusing on design of casting and wax model mould. This is followed with creation of the CNC machine control program as well as choice of the moulding mixture and finally description of such casting. The experimental section is concluded by brief description of casting test and evaluation of the quality and accuracy of cast parts.

The issue of biotic attack of ETICS
Těžká, Adéla ; Žák,, Antonín (referee) ; Žižková, Nikol (advisor)
This bachelor thesis deals with the issue of biotic attack of ETICS contact insulation systems. The theoretical part is focused on the individual components of ETICS, both from the point of view of materials and from the point of view of individual steps. In addition, there are organisms that cause biotic attack on facades. The practical part deals with the possibilities of testing the resistance of the surface treatment of ETICS against biotic attack, both in laboratory conditions and in the exterior.

A proposal and production of vacuum mold for serial production of plastic forming
Tišnovský, Jakub ; Chladil, Josef (referee) ; Sedlák, Josef (advisor)
This diploma thesis deals with the proposal and production of a mold for series production of plastic parts by vacuum forming. The thesis is divided into 2 main chapters. The theoretical part includes analysis of chip machining technology. The experimental part focuses on solving the design of the mold in PowerShape software, a detailed analysis of making of the model for casting and about making of the mold themselves. In the last part the manual completion and verification of the mold is discussed. Thesis is terminated by technical-economic evaluation, in which is discussed about production costs.
