Design of manufacturing technology for motorcycle headlamp body
Nosek, Jan ; Urbanec, Antonín (referee) ; Kandus, Bohumil (advisor)
The thesis is a proposal technology of the main body of motorcycle polymer material from Bayer's APEC - high temperature polycarbonate 1703. Literary study summarizes findings from a thermoplastic injection molding technology and the possibilities of structural design of injection molds, plastic plating technology from a focus on the most important technology in the field of lighting technology vehicles. Given the anticipated production run of 50 thousand. pieces are assessed a total of 2 variants of the molding parts. The practical part was modeled and specified product designed mold. Construction was done by using SolidWorks 2007 software and normalities FCPK Bytów and HASCO. For the selected option is implemented technological calculations. For the proposed technology was chosen Allrounder injection molding machine 570 A the manufacturer Arburg designed and suitable technological process of production.

Production technology of plastic porter for ammunition
Hejl, Dušan ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
Dissertation deals with solution of production of set component „plastic porter for ammunition“. Component is made from high-density polyethylene with business marking LITEN ML 77, suggested series of 3 000 000 pieces. On the basis of literary study of plastics injection problems and necessary calculations, there was proposed injection form. This form is solved by means of normalised components from company Meusburger. There was chosen injection machine from company Arburg Allrounger 370 S 700 – 170.

Design of manufacturing technology for plastic hung
Popelka, Jan ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
The aim of my graduation theses is to work up the literature search of polymer processing. To give a short summary of their structure, characteristic and fabrication technique. Then to make a structural design of injection mold for producing the scheduled aim and motivate this design with requisite calculation for construction of the tool, a choice of injection machine and rundown of injection cycle. At the end of my work is this aim economically reviewed and compared with alternative form of structural design.

Development of multilayer polymer floor systems
Tesař, Filip ; Vyhnánek, Miroslav (referee) ; Petránek, Vít (advisor)
Multilayer polymer flooring systems belongs to widespread materials for industrial constructions and also for public constructions. These are mostly two-components polymeric materials based on epoxy. The main aim of my thesis is to make list of requirements for multilayer polymer flooring system and utilization of waste materials as fillers in polymer epoxy. Then use this knowledge for development of multilayer polymer flooring system and propose the new recipe and primary test´s for this material.

Heating Module for the Electrospinning Electrode
Lukesle, Václav ; Musil, Vladislav (referee) ; Pokorný,, Marek (advisor)
The thesis deals with the principal heating design of the electrospinning electrode. These electrodes are fed with high voltage (tens of kV), which is an essential part of the device for the nanofibres production. This thesis presents the research of possible solutions of the heating and also it analyzes some principles of the nanofibre production. Furthermore, the work presents electrical schematics and PCB of the heating module. The aim of this work is to propose such a solution of heating that makes spinning from melt realizable in the device for 4SPIN ® nanofibres production.

Optimization of electrochemical sensor for detection in microvolume
Gajdoš, Libor ; Pekárek, Jan (referee) ; Prášek, Jan (advisor)
This thesis describes optimization and modification of standard thick-film electrochemical sensor to be able to be used for detection in microvolumes. In the theoretical part, the thick film technology is described. The work is then focused on the wettability of surfaces followed by introduction to electrochemistry and electro-analytical methods. In the experimental part, screen-printing of various types of thick film pastes on ceramic substrates for determination of their wettability and the following modification of the sensors with thick-film paste and with Parylene vaporization can be found, as well as the basic electrochemical measurements in microvolume using the modified sensor. Finally the results are summarized in conclusion.
