Production of components 'COVER'
Václavek, Jiří ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The theory of plastic injection molding technology together with procedure of designing injection molds is elaborated in this master thesis. Also, the technology of production is designed, derived from assigned component „cover“ analysis affirmed by necessary calculations. On the bases of these calculations, injection machine fitting requirements is chosen. Then injection mold is designed for the assigned component. Simulation of injection is performed for this mold using Autodesk Inventor 2011 and its module Moldflow and then results are thoroughly analyzed. Economical evaluation for this component is then executed towards the end of the thesis.

Design of manufacturing technology for plastic program disc
Gráf, Radomír ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This thesis is concerned with the appropriate design of manufacturing technology for plastic program disc including the design of plastic printing technology. At the beginning of this thesis was made an analysis of requirements for manufactured device including selection of the most appropriate technology for its manufacturing – plastic injection. In the theoretical part are described all skills needed for designing and construction of the injection mould. Partial theoretical parts are concerned with the issue of plastic materials, tools and engines for injection, and of plastic printing technology. Practical part is concerned with description of design of each single system inside the injection mould including calculation. On the basis of these calculations was selected the appropriate injection engine. The end of the practical part is concerned with the selection of the appropriate engine for printing on the plastic device which is manufactured by the technology of plastic injection. For construction of the injection mould were applied normalities of the Hasco Company and the 3D CAD system Solidworks. The conclusion of this thesis achieves the technical- economical evaluation for manufacturing of designed plastic device.

Surface treatment of car body
Talafa, Michal ; Kandus, Bohumil (referee) ; Kubíček, Jaroslav (advisor)
In this work, the theory describes modifications to the car bodies, especially their finishes. Thus pretreatment before the coating lacquer layers. There are described the types of pre-treatment such as degreasing and corrosion protection. Also deals with the coating, and their functions and applications to the car body. Since the body does not consist only of metal, there is another part of the work focused on the plastics that are used and their painting.

The effect of manufacturing inaccuracies on the final light intensity distribution of an automotive headlamp
Březnová, Tereza ; Lysa, Bohuslav (referee) ; Novotný, Jan (advisor)
The thesis deals with the issue of headlamp defects arising during production and their impact on the resulting light trail. The thesis describes and analyses defects arising during individual correction loops. Their analysis was carried out in order to provide measures for other projects. The main defects that have been assessed include the position of the light source, the quality of the optical surfaces and the associated quality of the plating, inaccuracies of the optical surfaces, dimensional variations due to installation technology and defects on the cover glass. The proposed measures concern the pressing tool, accuracy of machining and surface polishing. The thesis also includes designing solutions for quick identification of the surface quality of the cover glass by remote projection. Individual defects were described by their originators, their seriousness and their reparability. Based on this information, recommendations for production are proposed.

Comparison of options in production of injection molds
Marko, Tibor ; Sliwková, Petra (referee) ; Kandus, Bohumil (advisor)
The project elaborated in frame of engineering studies branch engineering technology (2303R002) by comparing different methods of injection molding tool manufacturing. Set manufacturing method for each one of three selected plastic parts, particularly focused on cavity and core manufacturing. Various technological methods of manufacturing, material removal and forming plastic parts will be used for each cavity and core. Production research and economical evaluation will be developed based on given production processes and technology, which will determined which technology to use to pay off in economic terms, depending on the complexity of the plastic part.

Do you know what a fish will do when it runs up a hill?
Elznic, Zita ; Štroblová, Kateřina (referee) ; Rathouský, Luděk (advisor)
Diploma thesis entitled Do you know what a fish will do when it runs up a hill? concerns the topic of industrial fishing. Formally, it is an installation that contains two parts. The first part is an oval object on which are attached mechanical fish, which form a moving flock. Using engines, they interact with each other and the viewer accompanied by the song. The second part includes three separate mechanical fish, which create a direct dialogue with the viewer. The installation is located in a white cube. The result is to give the impression that the fish are alive and, with the help of a human voice, get closer to the viewer. Title Do you know what a fish does when it runs up a hill? based on a child's joke. This sentence is characteristic of the topic, in that it is all nonsense. The fish do not run, do not move on land and do not even talk. An attempt at this joke to humanize fish is quickly over when you know the answer. Just clapping tells us how foreign this different world is.

Development of materials used for downhill skis production
Václavík, Martin ; Jech, David (referee) ; Pavloušková, Zina (advisor)
The submitted thesis is a retrieval type and is concerned with the technologies and materials used in the manufacture of downhill skis with a deeper focus on the last ten years. Examined are materials for the manufacture of ski cores as well as other parts of the ski, and that in terms of comparison of the construction materials and technologies. Listed are basic elements and characteristics of skis, methods of manufacture, materials for the manufacture of individual parts of the skis and, last but not least, the types of skis. The work is eked out with the analysis of several samples of skis, on which were made cuts, they were observed and structures were compared. The aim of this observation was to determine whether the materials found in the practical section corresponds to the information contained in the theoretical part.
