Abstract U ovom završnom radu je opisana prerada polimera, odnosno dobivanje polimernih prerađevina različitim postupcima. Uz navedene postupke obrade polimera, detaljno je opisana proizvodnja injekcijskim prešanjem. Navedeni su materijali koji se koriste u proizvodnji i obradi polimera s naglaskom na materijale koji se upotrebljavaju u injekcijskom prešanju. Opisana je i objašnjena sva potrebna oprema za proces injekcijskog prešanja, a također operacije i aktivnosti vezane uz navedeni proces (montiranje, kontrola kvalitete, pakiranje i skladištenje). Ukratko su spomenuti roboti proizvođača Sepro koji su vezani za sam proces injekcijskog prešanja, koji navedenom procesu daju brži ciklus, a samim time i veću efikasnost i produktivnost. U eksperimentalnom radu detaljno je obrađen postupak injekcijskog prešanja, odnosno dobivanje gotovog proizvoda od granulata (materijala) do gotovog traženog proizvoda. Ponovno je spomenuta potrebna oprema za izvođenje procesa, ali u ovom slučaju ona koja se koristila prilikom dobivanja gotovog proizvoda. Karakteristike opreme su prikazane tablično, a proces dobivanja proizvoda je uz tekst potkrijepljen i slikama. U eksperimentalnom radu, naglasak je bio na optimiranju i korekciji parametara koji su najbitniji za dugotrajnost i kvalitetu provođenja injekcijskog prešanja. Procesi koji najviše pomažu za shvaćanje samog procesa su injektiranje i kaskadno upravljanje sapnicama izraženo u ovom slučaju kroz put [s]. Osim kroz put, postoji mogućnost da se navedeni procesi izraze kroz vrijeme [t]. Uz glavne parametre spomenuti su i objašnjeni ostali parametri (vrijeme hlađenja, plastificiranje, temperature kalupa i cilindra) koji također uvelike doprinose kvaliteti provođenja procesa. U zaključku je ukratko spomenuta raširenost i konzumacija općenito plastike, tako i polimera. Također navedena je i lošija strana plastike, a to je prije svega zagađivanje okoliša.
Abstract (english) In this master thesis polymer processing is described, ie the preparation of polymeric processes by various methods. In addition to the above polymer processing methods, injection molding is described in detail. These materials are used in the production and processing of polymers with emphasis on materials used in injection molding. All necessary equipment for the injection molding process as well as operations and activities related to the mentioned process (assembly, quality control, packaging and storage) are described and explained. Briefly mention the Sepro robots which are linked to the injection molding process itself, which provide a faster cycle, and therefore greater efficiency and productivity. In the experimental part of thesis , the process of injection molding is described in detail, ie obtaining a finished product from granules to finished product. The equipment needed to carry out the process was again mentioned, but in this case the one used to obtain the finished product. The features of the equipment are shown in the table, and the process of obtaining the product is supported by the text with the pictures. In the experimental part of thesis, the emphasis was on optimizing and correcting parameters that are most important for the longevity and quality of injection molding. The processes that help to understand the process itself are injecting and cascading the nozzle management expressed in this case through the path [s]. Except for the way, there is a possibility that these processes are expressed through time [t]. The main parameters are mentioned and explained other parameters (cooling time, plasticisation, mold temperature and temperature of cylinder) which also greatly contribute to the quality of the process. In conclusion, it is briefly mentioned the widespread use and consumption of plastics in general, as well as of polymers. Also, worse side plastics are mentioned, primarily environmental pollution.
