Design of manufacturing technology for elastomer bushings conditioning
Švarc, Lukáš ; Dubovský, Marek (referee) ; Kandus, Bohumil (advisor)
This thesis is dealing with designing technology of manufacturing for component made of elastomer. The theoretical part is about dividing polymer materials and the issues of elastomer processing by injection molding. In the practical part is dealt with production conditions, design specifications of the tool and comparison with initial proposal. Next part is about technological and design calculations and the thesis ends with design of technological process.

Production technology of a plastic headlight panel in a car
Vrána, Petr ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
Diploma thesis which is developed for the master’s degree program (M2I – K Mechanical engineering) presents a proposal solution for production technology plastic car headlins parts from polymer material PBT GF30. Literature review summarizes the findings of thermoplastic injection technology and the structural design possibility of injection molds. The paper examined two variants of the running system, which are suitable for production of injection molding components. Finaly, after technical - economic assessment, we came to the conclusion that the better option is to use the hot runner system. In the practical part is the specified product modeled by the help of 3D software and the injection mold was designed. The design was implemented by CATIA V5 R20. For the design and manufacture of injection mold were used normality from MEUSBURGER. For the chosen alternative technology of production were made calculations and was selected injection molding machine Electron 75 – 300 from FERROMATIC.

Control System For Small Injection Molding Machine
Novotný, Jan
This paper deals with design and realization of control system in application for smallinjection molding machine. The small injection molding machine is intended to serve as a substitutefor 3D printers in company, thus reducing producing time and improving mechanical properties offinal product. The main goal was to design its own control system, which will be more cost-effectivethan using a PLC. An integral part was also the assembly, commissioning and programming of itsown control system.

Technology of injection molding of thermoplastic test specimens
Khamzin, Yersin ; Petruš, Josef (referee) ; Kučera, František (advisor)
The diploma thesis focuses on the optimization of technological parameters of plastic injection molding and the study of the influence of technological parameters on the quality of molded test specimens’ type 1A. The quality of molded parts for 3 types of polypropylene (PP) with different melt flow rate (Mosten GB 002, Mosten GB 218, Mosten MA 230) and 1 type of polystyrene (PS) (Krasten PS GP 154) was evaluated in terms of dimensional stability and weight. The contribution of software for modeling the plastic injection molding process was evaluated in this work. SOLIDWORKS Plastics software was used to optimize technological parameters. The construction of the bodies, mold and cooling system was constructed, and test bodies were produced on the basis of parameters obtained from the simulation of the injection molding process. Their quality parameters were compared with a 3D model and for each of the studied materials the optimal technological parameters were selected in terms of quality and the degree of influence of individual injection parameters on the quality of moldings was evaluated. The accordance of the results of the theoretical simulation with the real experiment was proved and a computational module independent of the optimized quality parameters, generally suitable for optimizing the quality parameters of the injected parts, was developed.

Production technology of plastic carrier information
Krejčí, Radek ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This bachelor's diploma thesis presents a proposal for the production technology of plastic carrier information, which is produced using injection molding technology. In the general literary study, plastic materials and injection molding technologies are analyzed. In the practical part of the thesis, the material of the plastic carrier information is selected. From the calculated technological parameters, the design of the injection mold is created and a suitable injection-molding machine is selected. Finally, a technical-economic evaluation is carried out, in which the cost of producing one piece of plastic carrier information is calculated.

Production technology of the connector body from recykled material
Brhel, Michal ; Sedlařík, Vladimír (referee) ; Kandus, Bohumil (advisor)
Study developed during the Master's degree studies of Mechanical Engineering deals with the use of recycled plastic in the injection molding and its influence on the mechanical properties of the mold. Examined product is used in the automotive industry as a connector body. The housing is manufactured from a plastic material, polyamide. The annual production volume of 3 000 000 pieces. According to tests specified in standard USCAR2 regrind influence on mechanical properties and dimensions was evaluated. After the technical evaluation of the project, research was also judged from economic point of view. In this task, savings with the different content of the recycled material during production was calculated. The final chapters justify change of properties and they are proposing the use of recycled materials in practice.
