Design of manufacturing technology for plastic mount carbon
Fojtík, Jakub ; Mořkovský, Václav (referee) ; Kandus, Bohumil (advisor)
This master thesis deals with design of injection moulding technology for plastic holder of carbon brushes made of polycarbonate labelled Lexan 945A. The injection is performed into injection mould with hot runner system. Initially there is general study related to plastics and injection moulding technology. Further the study continues with injection moulds with hot runners and ends with computer analysis of injection moulding process. The designed injection mould for production of plastic holders is three-plate, double cavity mould with four hot nozzles and one parting plane, where one of the plates serves for mounting of the hot runner system inside the mould. This work contains part of the drawing documentation and item list of the injection mould. The selected injection moulding machine is Arburg Allrounder 370 U labelled 700-290 according to EUROMAP.

Production single parts from thermoplastic
Ruibar, Jakub ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The project developed in terms of engineering study of field N2307-00 Engineering Technology submits a design of components from plastic production technology – centre ring of labels on CD. In literary study there are summarized the basics of technology issues in elaboration of plastics injection into the metal form. The work includes production of component technology assessment and design of component production technology. Furthermore, the work includes the design of constructional solutions injection form, the option of suitable material of injection and the injection machine as well as the economic classification of production. As part of this diploma work is also considerations process of injection through the use of simulation program Moldex3D. This work is supported by appropriate drawing and appended documentation.

Design of manufacturing technology for car carpet
Kavan, David ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
The main goal of this bachelor thesis is design of a manufacturing technology for car carpet made from a thermoplastic elastomer. Car carpet will be produced by injection molding with a hot runner system in a series of 42 000 units per year. At first there is an analysis of the current technologies, enclosed with a summary of reasons for the changes in manufacturing technology. Then following is a general review of the literature relating to plastic materials and injection molding technology. In the practical part a suitable material is chosen, injection molding machine is chosen according to calculated technological parameters and a conceptual design of an injection mold for car carpet is executed. The last part is a technical and economical evaluation comparing the current production technology with the newly proposed technology.

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.
