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.

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.

Materials for Passenger Car Bodies
Vondrák, Zdeněk ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This work is devoted to description of modern personal car body construction, materials of car bodies, surface finishing and methods of body parts joining. The work presents a list of materials that are used during manufacture of individual parts of body. Further, the work is concerned with surface finishing methods, especially those focused on anti-corrosion protection. The final part deals with various options of joining, that we may encounter in the automobile industry.

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.

Injection moulding
Heralt, Aleš ; Balej, Zdeněk (referee) ; Žák, Ladislav (advisor)
This Bachelor´s thesis is focused on construction forms for injection of thermoplastic matters. The technology for plastic products production is technology that participate more and more in production of all sorts of products - from technical components over kitchenware after as much as toys. Main part of this thesis is focused on description of the injection valve, ejector, annealing and ventilation system forms for injection with the main structural principles.

Processing art sculptures relative to the issue of eating disorders
KONEČNÁ, Monika
This thesis deals with the problems of eating disorders. Objective of the thesis is definition of eating disorder, a description of the individual faults an as a practical part there is an artistic creation of specific disorders. Theoretical part includes characteristics, division and insight into history. There are described four forms of eating disorders: anorexia, bulimia, obesity and bigorexia. In the practical part is the visual processing of transformation of two excessive eating disorders- anorexia and bigorexia. It is treated as a sculpture ceramic including drawing.

Historical development and conditions in processes with separated municipal waste in Czech republic
MOJŽIŠ, Lukáš
The aim was to map the first and second link in the chain municipal waste management, particularly with municipal sorted waste. I focused on the core components of municipal waste - paper, plastic and glass. The thesis examined public awareness about waste, how well informed they are and whether people are interested in products made from recycled materials. The second part was to describe the situation in a company dealing with waste, described problems are encountered and to find the steps that would lead to improve this situation

Influence of release frequency of containers for separated household refuse to separation intensity of the waste.
JANEŠÍKOVÁ, Michaela
The thesis is evaluating the influence of frequency balance of containers for sorted for sorted waste for the intensity of sorting in two locations in České Budějovice. The influence was examined using three independent methods (monitoring the filling of containers ? by a balancing caluclation ? by a questionnaire) At the assessment of the impact of collection frequency to the selection account was taken of the following criteria: full containers at the time of collection, walking distance of population to the containers for sorted waste, type of buildings in the monitored area, sorted waste containers capacity, the amount of sorted waste, population per one collection point, etc. The results showed that the level of sorting of mixed waste in České Budějovice is not at good level. Collection frequency of sorted waste is sufficient and is not limiting to the intensity of sorting. For the efficiency of collection there is proposed tu optimize the placement od containers for sorted waste, to consider a different system off collection for residential areas, to introdukce a special containers for sorting of PET bottles and to raise form filling of paper containers by englightenment.
