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.

Dielectric Properties of Thermoplastic Materials with Ground Mica
Fiala, Ivo ; Havlíček, Svatopluk (referee) ; Polsterová, Helena (advisor)
The subject of this thesis are composite materials, measuring of their dielectric qualities, particularly of the polyamide and the polyamide filled with various weight percentage of the ground mica. The essential intent of the thesis is to determine the measuring methodology and respective measurement of the basic dielectrical quantities of materials, as are loss factor and the complex permitivity components. The measuring should be done for various temperature and humidity combinations. The thesic contains the physical explanation of measured dependences.

Optimization of wall thickness for headlamp body
Prokeš, Radim ; Tomaj, Martin (referee) ; Kandus, Bohumil (advisor)
This project is concerned with the issue of the thickness optimalization of the wall thickness of the plascics headlamp housing by the simulation Moldflow analyse. There are mentioned the basic information about the plastic materials and their dividing over there. Furthermore the description of the injection process, the injection machines and the tools is included. The principles of the proposal and the construction of the plastics part is also mentioned here. In the application of the Moldflow Plastics Insight 6.0 there is provided the simulation of the melt moldflow for the proposed headlamp housing. Based on this analyse the proposal of the thickness reduction of the wall thickness of the headlamp housing is worked out with the aspect on the required qualities. It also contains the technoeconomic estimation of the benefit optimalization.
