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.

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 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.

Design of manufacturing technology for plastic cogwheel
Vyhnanovský, Jaroslav ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This project has been developed within the master study of Engineering Technology and Industrial Management a design of manufacturing technology for plastic cogwheel is introduced. The cogwheel will be produced by plastic injection moulding. POM material with a trade name Delrin 100 NC010 from DuPont Company will be used. An injection mould is a tool for producing a plastic cogwheel using injection moulding technology. Production will take place on the machine Allrounder 420 C Golden Edition 1000-290 from Arburg German Company headquartered in Loßburg, where the seat of parent company is situated.
