In questa tesi, saranno dimostrati e discussi possibili miglioramenti e nuove idee concettuali sulle macchine per lo stampaggio di EPP (polipropilene espanso). La tesi sarà condotta con l'aiuto di Alessiohitech SRL che è una delle migliori aziende in Italia, nel campo della progettazione e produzione di macchine per stampaggio EPP. Requisiti, vincoli e condizioni sono stati fissati con loro. Quando ho iniziato la mia tesi, i primi requisiti che mi sono stati detti erano: "ridurre il tempo richiesto per il processo" e "ridurre l'energia richiesta per il processo". Questi requisiti ovvi e ampi hanno acquisito una definizione più specifica con il tempo. Dopo aver valutato il sistema e la recente tecnologia sul campo, alcuni miglioramenti ragionevoli sono diventati lentamente più evidenti con il passare del tempo. Prima di stabilire nuovi obiettivi specifici, sono stati dichiarati lo scenario di progettazione e i requisiti del sistema. Una volta che i requisiti sono giunti alla conclusione, è stato creato il criterio di prestazione desiderato. Per raggiungere questi nuovi valori prestazionali, sono state esaminate molte idee diverse, comprese quelle ovvie e non ovvie. Mentre queste idee vengono generate, la letteratura e il mercato di questo campo vengono controllati costantemente. Alla fine della tesi, alcune delle migliori idee sono state discusse in dettaglio considerando i loro punti di forza e di debolezza. Durante la lettura di questa tesi bisogna tenere presente che ci sono solo due obiettivi principali che sono la riduzione del tempo e l'energia necessaria per elaborare un singolo processo di stampaggio.

Abstract
In this thesis, possible improvements and new conceptual ideas about EPP (Expanded Polypropylene) moulding machines will be demonstrated and discussed. The thesis will be conducted with the help of the Alessiohitech SRL which is one of the top companies in Italy, in the field of EPP moulding machine design and manufacturing. Requirements, constraints and conditions have been set with them. When I started to my thesis, first requirements that have been told me were, “reduce the required time for the process” and “reduce the required energy for the process”. These obvious and broad requirements gained a more specific definition with the time. After evaluating the system and the recent technology in the field, some reasonable improvements slowly became more obvious with the time. Before setting new specific goals, design scenario and requirements of the system has been stated. Once requirements came to a conclusion the desired performance criterion has been created. To reach these new performance values, many different ideas including obvious and non-obvious ones have been examined. While these ideas are generated, literature and the market of this field are checked constantly. At the end of the thesis, some of the best ideas have been discussed in detail considering their strengths and weaknesses. While reading this thesis it has to be kept in mind there are only two main goals which are decreasing time and the energy required for processing a single moulding process.| File | Dimensione | Formato | |
