Waste horizon
Ochotná, Barbora ; Rypl Žabčíková, Ada (referee) ; Kristek, Jan (advisor)
The city is a place of accumulation, production and reproduction of production resources and consumption of goods, but waste typically accumulates outside it. It falls out of our horizon physically and mentally. The waste we produce changes the landscape and transforms the processes on earth without most of us visiting the "places of transformation". The project works with the idea of redirecting the final phase of the production chain back to the place of consumption by producing elements of public space from municipal waste. The presentation of waste leads to an awareness of its amount and degree of consumption. At the same time, waste becomes something much more ambivalent, possibly useful or even beautiful.

Design of manufacturing technology for plastic cogwheel
Vyhnanovský, Jaroslav ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This project has been developed within the master study of Engineering Technology and Industrial Management a design of manufacturing technology for plastic cogwheel is introduced. The cogwheel will be produced by plastic injection moulding. POM material with a trade name Delrin 100 NC010 from DuPont Company will be used. An injection mould is a tool for producing a plastic cogwheel using injection moulding technology. Production will take place on the machine Allrounder 420 C Golden Edition 1000-290 from Arburg German Company headquartered in Loßburg, where the seat of parent company is situated.

Robust wheeled robotic chassis
Jirges, Radek ; Chalupa, Jan (referee) ; Bastl, Michal (advisor)
This thesis deals with the issue of the proposal of mobile wheeled robotic chassis. In the introductory theoretical part gives an overview of the division of mobile chassis inclu-ding representatives of each group. In the begining of the practical part describes se-lection of suitable components for the chassis from drivetrain to controlling electronics. Constructional part of this thesis at first deal with selection of suitable material for each part of chassis and than follows construction of these components including decsription of used constructional solutions for each issue. Result of this thesis is robust wheeled chassis fitted with drivetrain and basic electronics.

Technical viscous curve for injection molding
Hejkalová, Anna ; Svoboda, Jan (referee) ; Kandus, Bohumil (advisor)
Injection molding is highly dependent on flow qualities of plastics. The bachelor thesis compares the conventional measurement of their rheological attributes with the method of injection molding to the technical viscous curve. This method enables to determine the optimum injection rate at which injection resistance does not allow significant improvement of the melt’s flow attributes, on the contrary increases the energy consumption of the process. At the same time, the thesis tries to prove the advantage of this method.

Use of thermally conductive non-metallic materials for cooling systems in automotive lighting technology
Zachar, Martin ; Makki, Zbyněk (referee) ; Vitkovič, Pavol (referee) ; Kotrbáček, Petr (advisor)
This thesis deals with the use of non-metallic highly thermally conductive materials, more concrete-ly special plastic materials, enriched with highly thermally conductive additives, for the purpose of passive cooling of a given heat source. The thesis compares the effectivity of these heat sinks with the classically used materials, specifically aluminium. The thesis is divided into two main sections, theoretical and practical. The theoretical part deals with a constantly growing need of LED (Light Emitting Diode) chips cooling in automotive head-lamps, where the new materials could be put into effect, analyses possible replacement of classic aluminium heat sinks with different materials with a significantly lower thermal conductivity and introduces problems of such materials. The practical part applies the problematic described in the theoretical one on the actually produced heat sinks, which are compared among themselves, with regard to their method of production, as well as with aluminium counterpart in different conditions. Furthermore, the problematic of de-signing a heat sink made from material which is characteristic for its highly anisotropic thermal con-ductivity is dealt with. The end of the thesis shows the importance of heat dissipation via radiation, which can have a great significance in case of plastic heat sinks and in a specific applications.

Design of manufacturing technology for plastic plug
Kočí, Ivan ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
This graduation theses analyse a concept of plastic plug production using the technology of injecting plastic into the form. There is performed a design of the technologic process with necessary calculations included here. Besides that the analysis is also focused on construction of the injection form. For the solution the 3D CAD system by SolidWorks and Hasco, Meusburger, Synventive normals were used. The graduation theses is finally valorized by technological-economic summary.

Production technology of plastic base device with terminal
Horník, Tomáš ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
Master’s thesis deals with selection of a proper technology for manufacturing of chosen plastic part. The beginning of thesis contains part survey. Plastic injection was chosen as the most suitable manufacturing technology. Required theoretical knowledge for plastic injection mould designing were extracted in the recherche. Individual chapters deals with plastics, their manufacturing and plastic injection technology with all required knowledge about this technology, machines and moulds. Designing chapter contains every required calculation for mould design and all individual sections of mould design and injection machine selection. Injection simulations and their evaluations are part of this thesis aswell. Assembly and forms drawings as well as other documents used during thesis processing are included in the attachments.

Production single parts from thermoplastic
Michalčák, Jan ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The project elaborated in the frame of engineering studies branch N2307-00 is submitting design of a product from plastic from material PP GF30. In the frame of literal study there are summarized technical knowledge from the area of plastic processing. On its base there is selected and specified technology of plastic injection and costruction of injection mold. Thesis is further dealing with the construction of injection mold, which is solved as a 1+1 multiple with the use of side sliding flank cores. During the course of the tool construction there were used standardized elements of Hasco company. The tool will be fixed by the use of Arburg ALLROUNDER 320C injection press. In the conclusion of the thesis there are verified necessary strenght of the mold and basic production cost analyses.
