Technology design manufacturing plastic worm gear
Petrucha, Roman ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
The master thesis deals with the design of the injection mold for the production of a plastic two-part worm which is part of the worm gear set in the sleeve. From the beginning, an analysis of the assigned component was performed, specifying its function and specifying the criteria that must be met by the component. In addition, design of the production technology (injection molding) was carried out, followed by theoretical analysis of plastic materials, injection molding technology and mold design. Subsequently, in the practical part, a complete design of the injection mold was made on the basis of simulations and technological calculations. On the basis of the parameters of the injection mold, a machine was chosen, on which production should be carried out according to the proposed technological procedure. The conclusion of the thesis contains a technical and economic evaluation of the proposed technology for the production of Plastics splatter component.

Machining of polymericMaterials
Ondráček, Ivo ; Němec, Karel (referee) ; Molliková, Eva (advisor)
This bachelor’s thesis deals with the machining of polymeric materials and the major differences between the machining of metals and polymers or plastics. Introduction describes the basic elements in the history of the discovery and use of plastics. The thesis focuses on the basic division, further definitions and internal structure of the polymers. There are also discussed the most widely used machining technology and requirements for tools and materials. At the end of the work we are specified properties and selected types of plastic materials intended for processing. Practical informations were obtained during the visit to Brno company Belt Plast, Ltd.

Design of manufacturing technology for headlamp body
Pytlík, Radek ; Tomaj, Martin (referee) ; Kandus, Bohumil (advisor)
The project developed within the Master's degree is proposing a technology of manufacturing a headlight housing from the high temperature polycarbonate Apec 1695 with wall thickness of 1.8 mm. The batch size is set at 100,000 units / year. Based on literature studies of injection moulding and also on the calculation method, the injection moulding tool with the heated injector has been proposed. The injection moulding machine Allrounder 630 S 2500-800 from Arburg is used for the production of the plastic headlight housing.

Production technology of plastic body aperture
Dluhoš, Jan ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This thesis deals with the production of a plastic body of the aperture by the method of injection moulding. The work includes a design of the injection mould for the given component. First, an appropriate material for the moulded piece was chosen and then the necessary calculations for the injection mould were made. A quadruplex injection mould with a heated inlet nozzle and pullout cores was designed based on these calculations. Modular components were chosen when designing the injection mould. The next part of the thesis contains the selection of the injection moulding machine for the given mould. The conclusion contains a technical-economical evaluation including the cost estimating for the injection mould and cost estimating for one moulded piece.

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.

Technologie výroby termoplastů
Korbička, Jiří
This thesis deals with plastics with more focus on thermoplastics, from production, through use, to refurbishment and joining. In the first part of the thesis describes the basic division of plastics used in practice. The second part is focused on thermoplastics, their production and use. Furthermore, this section describes the properties of individual plastic covers some standards, or explanation, according to what is determined. In the third part is evaluated joining plastic parts. The most widely used technologies are described and explained in detail what kinds of welding is appropriate, or where it is better to combine the parts such as adhesive bonding.
