Design of manufacturing technology for plastic hung
Popelka, Jan ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
The aim of my graduation theses is to work up the literature search of polymer processing. To give a short summary of their structure, characteristic and fabrication technique. Then to make a structural design of injection mold for producing the scheduled aim and motivate this design with requisite calculation for construction of the tool, a choice of injection machine and rundown of injection cycle. At the end of my work is this aim economically reviewed and compared with alternative form of structural design.

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 flexible plastic clip
Mikulenka, Martin ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
Currently, the plastics industry has a wide range of applications due to the possibility of a fully automated process or through increased production efficiencies. The reason for this choice of the thesis was to understand the whole issue of plastic injection molding process. The specified component is used to atach the sail, which serves to protect workers in the welding sector. A specified number of the series is 350 000. The work includes a theoretical problem of injection molding process, selection of technology, material selection and design of mold. An integral part of every design mold is a simulation of injection, which is also included. In conclusion of thesis is the calculation of the various stages of production and operation of the injection mold.

Optimization of the vacuum deaeration of the injection mold
Rohlínková, Marie ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
The project elaborated design of optimization venting of molds exhibiting bubbles or low quality weld lines. Based on a literature study of the injection mold venting, the use of vacuum venting, namely the VACUUMJET system of the Spanish CUMSA manufacturer, has been proposed. The experiments proved the elimination of bubbles in the part and the marked improvement of visual quality of the weld lines. The effect on the closing force was not confirmed. The use of the system is more economical for larger batches production, or when high quality parts are required that allow price increasing.

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.
