20.500.12556/RUL-98463 Analiza brizganja polipropilena s prototipnim konformno hlajenim polimernim orodjem Analysis of polypropylene injection molding with conformal cooled prototype polymeric tool V magistrskem delu je predstavljena študija izdelave maloserijskega testnega izdelka iz polipropilena, injekcijsko brizganega v prototipno polimerno orodje, ki je izdelano s tehnologijo hitre izdelave orodja Polyjet. Z uspešno integracijo polimernega orodja v obstoječe modificirano orodje smo zagotovili hitrejšo pripravo na proces in povečali njegovo prilagodljivost. Z namenom učinkovitejšega hlajenja polimernega orodja je bil izdelan konformni hladilni kanal pod površino gravure izdelka. V procesu injekcijskega brizganja s „soft-tooling“ tehnologijo smo izdelali 60 testnih izdelkov z različnimi osnovnimi parametri injekcijskega brizganja, na katerih smo izvedli analizo vpliva parametrov na dimenzije, oblike in napake izdelkov. Na podlagi testa hlajenja polimernega orodja s hladilnim kanalom smo zaznali močan vpliv hlajenja, čeprav je polimerni material v osnovi manj toplotno prevoden kot jeklo. In the following master’s thesis a study was presented the production of small-sized test product made of polypropylene, injection molded into a prototype polymeric tool, which is manufactured using rapid tooling technology Polyjet. With the successfully integrated polymer tool into existing modified tool, we have provided faster preparation for the process and increased its flexibility. For the purpose of more efficient cooling of the polymer tool, a conformal cooling channel was built below the surface of the product cavity. In the process of injection molding with soft tooling technology we made 60 test products with different basic process parameters on which we analyzed the influence of the parameters on the dimensions, shapes and defects of the products. Based on the cooling test of the tool with the cooling channel, a strong influence of cooling was observed despite the poor thermal conductivity of the material of the polymeric tool. injekcijsko brizganje hitra izdelava orodij polimerno orodje konformni hladilni kanal polipropilen injection molding rapid tooling polymer tool conformal cooling channel polypropylene true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2017-12-03 07:15:08 2017-12-03 07:15:13 2023-11-10 12:50:12 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2018-12-01 204161 1394.pdf 1394.pdf 1 2029CA986F807702DA8613D549307665 dc8cbcf302675d367bcd75b50af313f185ff2915b3f975cb6f85c290c6ab9a30 66e08c0e-a1b4-11eb-a523-00155dcfd717 20.500.12556/rul/90fa2a37-6628-4c12-9da4-3a62ba2c217c https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=107739 Fakulteta za strojništvo 0 0 0
