Production single parts "Spacing cover"
Pšenka, Jakub ; Štroner, Marek (referee) ; Žák, Ladislav (advisor)
The bachelor thesis was written within the field of B-STG manufacturing technology. It concerns with the proposal for production of specified plastic part made from material PA66-GF30FR using injection modling technology. In the introduction is summary of current production status and description of basic plastic properties, principles of injection molding, injection modling machine and injection mold. In practical part is solving of mold design. In conclusion is the simple economic assessment of costs and benefits.

Manufacture of AC / DC adapter housing
Vašíček, Lukáš ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
The bachelor's thesis proposes an injection mold for the production of a plastic adapter. Based on the evaluation of the technological possibilities of the production of a plastic product, the technology of plastic injection was chosen. The first part of the work is devoted to a theoretical explanation of plastic materials, injection molds and machines. The practical part presents and develops a complete design of the injection mold, including the selection of a suitable material. The mold is designed four times with a cold inlet insert. At the end of the work is a technical - economic evaluation of production.

Metallization of technical plastics for lightweight traffic components with reduced fuel consumption
Sanetrníková, Dominika ; Boušek, Jaroslav (referee) ; Šimůnková, Helena (advisor)
The beginning of this thesis is dedicated to polymeric materials, which include plastics an composites. Plastics are shortly divided into two groups, thermoplastics and thermosets. The following part is the use of plastics and composites in traffic industry and briefly this work focuses on techniques of recycling of this materials. This work also focuses on the techniques of thin film deposition, electroless plating, electrodeposition as well and plating in the vacuum environment. special techniques of thin film deposition are also mentioned shortly. The coatings of polymer including cleaning and surface activation is introduced using various techniques including plasma treatment. The surface treatment of polyetheretherketone (PEEK) is included too. The final part describes performed experiments and discussion of results.

Production single parts "Case of coil winding"
Rudolf, Bronislav ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
Bachelor´s thesis is elaborated in terms of branch B-STG engineering technology. Smoothing - out suggestion manufacturing engaged plastic parts from material PA66- GF25 FR by the help of injection technology. Firstly, the basic materials for injection are described, then is described injection principle, injection mold and injection machine. The practical part deals with their own forms of construction. In the inclusion is simple economics upward revaluation expense and surplus.

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.

Optimization of technological parameters of injection plastic parts
Ulrich, Josef ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This thesis describes the optimalization of technological parameters during commissioning of injection mold manufacturing. In the introduction, there is general literary studies of plastics, injection molds, injection holding machine, injection holding technology and their effect on quality. The practical part includes an analysis of current state, calculation of injection parameters, moldflow analysis and sampling on the machine. Finally, there is choice of optimal injection holding parameters, design of workplace and technical-economic evaluation.

Plastic plating
Čermák, Jan ; Kubíček, Jaroslav (referee) ; Žák, Ladislav (advisor)
The perspective of the production of plastic parts has helped to spread the metallization of these parts on a large scale. Whether a coating is functional or just decorative. This bachelor thesis presents a comprehensive study, analysis, evaluation and comparison of the possibilities of creating metal coatings on plastic materials. The thesis deals with galvanic, chemical, vacuum and special methods of plating. For all the mentioned methods of plating, the technological procedure, equipment for plating, evaluation of individual methods and analysis of the use of plated plastic parts are given.
