20.500.12556/RUL-183803 Optimizacija brizgalnih parametrov za zmanjšanje porabe električne energije pri zabrizgavanju polimernega izdelka s kovinskim jedrom Optimization of injection molding parameters to reduce energy consumption in overmolding a polymer product with a metal core Termoplastično obrizgavanje kovinskih insertov je zaradi taljenja plastike in visokih tlakov energetsko potraten proces. V sklopu magistrskega dela je predstavljen ciklus termoplastičnega obrizgavanja s podrobnim opisom vseh faz ciklusa. Utemeljeni so viri porabe električne energije z vidika strojne opreme in procesnih parametrov. S pregledom znanstvene literature so identificirani vplivi procesnih parametrov na porabo električne energije brizgalnega stroja. S pomočjo ključnih kazalnikov je izbran nabor vplivnih procesnih parametrov za praktično obravnavo. V metodološkem sklopu naloge je predstavljena oprema za meritev energije in način obdelave izhodnih podatkov za analizo specifične porabe električne energije. Izvedene so prednastavitve parametrov na znižanje porabe energije in časa ciklusa. Izvedene so meritve porabe energije in analiza vplivov parametrov z metodo Načrtovanja eksperimentov (DoE), s katerimi pridobimo odgovor v potencial pristopa optimizacije procesnih parametrov na nižjo porabo energije. Ocenjeni so potencialni prihranki na konkretnem stroju in v celotni proizvodnji podjetja. Thermoplastic overmolding of metal inserts is an energy-intensive process due to plastic melting and the high pressures involved. As part of the master's thesis, the thermoplastic overmolding cycle is presented, including a detailed description of all phases within the cycle. The sources of electrical energy consumption are identified from the perspective of machine equipment and process parameters. A review of the scientific literature is used to identify the effects of process parameters on the electrical energy consumption of the injection molding machine. Based on key performance indicators, a set of influential process parameters is selected for practical investigation. The methodological section of the thesis presents the equipment used for energy measurement and the procedure for processing output data for the analysis of specific electrical energy consumption. Parameter presets aimed at reducing energy consumption and cycle time are implemented. Energy consumption measurements are conducted, along with an analysis of parameter influences using the Design of Experiments (DoE) method, enabling an assessment of the potential of process parameter optimization for reducing energy consumption. The potential savings are evaluated for a specific machine as well as for the company’s overall production. poraba energije insertno obrizgavanje načrtovanje eksperimentov brizgalni stroji parametri brizganja energy consumption insert overmoulding design of experiments injection moulding machines injection parameters true false false [M.
