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.

Production of the Cartridge for stepper motor
Míka, Jiří ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
The work deals with the production of the cartridge for stepper motor from the newly selected material polyamide PA66GF which contains 30% fiberglass. The change requires the choice of a new production technology, which is injection molding. For technological reasons, it was necessary to modify the 3D model of the part according to the chosen production method. After calculating the important technological parameters, the plastic injection mold was constructed. It is made as a quadruple with a hot runner system and a cold sub-distribution, the plastic injection mold also contains sliders for side actions. The Allrounder 420 C GOLDEN EDITION hydraulic injection molding machine with a clamping force of 1000 kN was chosen for the mold. At the end, a technical-economic evaluation and comparison of the costs for the production of one part is carried out. The necessary drawing documentation was also made for the work.
