20.500.12556/RUL-118652 Optimizacija procesa injekcijskega brizganja izdelka iz materiala polioksimetilen Hostaform Injection molding process optimization of a polyoxymethylene Hostaform product V okviru magistrske naloge je bila izvedena optimizacija procesa injekcijskega brizganja izbranega izdelka iz polimernega materiala. Cilj optimizacije je bil doseči krajši čas proizvodnega cikla in ugotoviti vpliv šestih izbranih procesnih parametrov na dimenzije izdelka. V magistrski nalogi so predstavljene teoretične osnove procesa injekcijskega brizganja termoplastov, polimerni materiali in njihovi skrčki ter načrtovanje eksperimentov. Opisan je uporabljen sistem material – orodje – stroj, planiranje in izvedba eksperimenta, optimizacija procesnih parametrov in analiza rezultatov materialnih skrčkov. Optimizacija je bila izvedena po metodi načrtovanja eksperimentov z uporabo L27 Taguchijeve ortogonalne matrike. Velikost predelovalnega skrčka materiala polioksimetilen Hostaform smo določali na podlagi meritev orodnih vložkov in meritev izdelkov. In this Master's thesis, the injection molding process optimization of the chosen product was performed. The optimization objective was to achieve a shorter cycle time and to understand the effect of six injection molding process parameters on part dimensions. The thesis presents the theoretical foundation of the thermoplastic injection molding process, polymeric materials and their shrinkage and the design of experiments. It also includes the description of chosen system material – tool – machine, planning and execution of the experiment, process parameters optimization and analysis of material shrinkage results. Process optimization was performed by design of experiments method with L27 Taguchi orthogonal array. To determine molding shrinkage value of a polyoxymethylene Hostaform polymer measurements of mold cavities and parts were performed. proces injekcijskega brizganja procesni parametri materialni skrčki polioskimetilen Hostaform orodni vložki metoda načrtovanja eksperimentov injection molding process process parameters material shrinkage polyoxymethylene Hostaform mold cavities design of experiments true false false [M.
