20.500.12556/RUL-94963 Analiza vpliva parametrov brizganja na deformacije plastične krtače Analysis of injection moulding parameters on the deformations of plastic bristles Med procesom injekcijskega brizganja se plastični izdelki lahko krčijo in zvijajo, kar povzroči ne zaželjeno spremembo geometrije. Te napake povzroča več vplivov. Metodologija dela sloni na simulacijah brizganja, spreminjanju parametrov brizganja in sistematičnemu pristopu z metodo načrtovanja eksperimentov. Najboljši rezultate smo dobili pri visoki hitrosti pomika polža in nizki temperaturi orodja. Kljub temu, ti rezultati niso zadostni za odpravo napake. During the injection moulding process polymers are subject to shrinking and warping which cause unwanted change of geometry. These defects can be caused by many factors. The work methodology is based on injection moulding simulations, changing injection moulding parameters and systematic approach with design of experiments. We got the best results with the combination of high velocity of the screw and low temperature of the mould. Nevertheless, these results are not enough to solve our problem. injekcijsko brizganje polimeri polipropilen zvijanje krčenje simulacija brizganja načrtovanje eksperimentov injection moulding polimers polypropilene warpage shrinkage injection moulding simulation design of experiments true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-11 13:35:24 2017-09-11 13:35:24 2022-08-10 02:08:49 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 200076 836.pdf 836.pdf 1 764829AD00F990E57D37FD592ACC6F16 5235a4d5d0ae62e2103eb48cca7dc0e2bfd444fb6757792f40cc1dffa04555ed a59768bc-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/a7cd68c1-0005-4ccf-9b6c-5892de6f1f9f https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=103452 Fakulteta za strojništvo 0 0 0
