- ItemMěření deformace v dělící rovině vstřikovací formy při výrobě na bezsloupovém a sloupovém stroji(Technická Univerzita v Liberci, 2012) Sejna, Jiří; Ausperger, AlešThe following thesis focuses on the measurement of deformations appearing on injection mold plates during the injection cycle on both, tie-bar and tie-bar-less injection machines. The thesis further aims on defining the precious amounts of inaccuracies while fitting plates for polyamide 6, polycarbonate and the relevant injection mold part when different levels of clamping force are impacting on the injection machine under standard injection conditions. Concluding, the scientific insights of the handed in thesis can be used when setting injection cycle parameters, deciding for an injection molding machine and, finally, gives an idea on the quality of clamping mechanism in injection molding machines.
- ItemVliv nastavení parametrů na vstřikovacích strojích na celkovou rozměrovou přesnost výlisku a jejich následná kontrola(Technická Univerzita v Liberci, 2010) Sejna, Jiří; Ausperger, AlešThis bachelor´s thesis is focused on adjusting technical parameters on the press machine during mould pressing process and the impact of these adjustings on the dimensional accuracy of the pressed parts. The aim of this thesis is to compare different setting up of the most important parameters and to identify the settings leading to moulds within the dimensional tolerance. For this reason it is possible to use this thesis as a basis for a technologist at mould pressing.
