Production technology of plastic lamp shade
Čajan, Tomáš ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This master thesis deals with design of injection molding technology for plastic lamp shade made of polycarbonate labelled Lexan 925. The injection is performed into injection mold with hot runner system. Initially there is a general study related to plastic materials and injection molding technology. Further the study continues with technological solution of production of the lamp shade. The designed injection mold is two-plate, double cavity mold with two hot nozzles and is equipped with a thread-unscrewing machine. This thesis contains part of the documentation and item list of the injection mold, along with technical-economical evaluation of the developed solution.

Optimization of production technology for plastic cap tube
Majerčíková, Erika ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This thesis deals with the optimization of the production technology of the cap tube made by injection molding. Series production is set at 5 000 000 units per year; the minimum time of the production is 5 years. A literary study is developed, focusing on the technology of injection molding in molds including the possibilities of the optimization of the production by changing the structure of the mold. The practical part of the thesis is devoted to the optimization of existing mold with cold runner system for the production of the cap tube, using the hot runner system supplied by Synventive. The change of the structure of the mold involves changing the three plate mold to a two plate mold. It is about changing the fixed part of the mold in which the hot runner system is placed; it is composed of standards parts of the company HASCO. Based on the technological parameters the injection machine Krauss Maffei KM 80-380 CX is chosen. There is a technical-economical evaluation of the optimization of the production by using the hot runner system at the end of the thesis.
