Abstract

Tema ovog rada je optimiranje injekcijskog prešanje tankostjenog otpreska pomoću računalne simulacije u svrhu smanjenja utjecaja vitoperenja. Injekcijsko prešanje se smatra jednim od najvažnijih i najčešće korištenih postupaka obrade polimera. Stoga je u ovom radu opisan postupak injekcijskog prešanja, definirana su svojstva polimernih materijala te je prikazan pregled literature o uzrocima vitoperenja. Računalna simulacija je provedena u programu Moldex3D prema centralno kompozitnom planu pokusa na osnovi kojeg su dobivene optimalne vrijednosti parametara procesa za dobivanje minimalnog iznosa vitoperenja i prihvatljive ravnosti površine.

Abstract (english)

The topic of this thesis is the optimization of injection molding of thin-walled parts to reduce the impact of warpage. Injection molding is considered to be one of the most important and commonly used polymer processing process. Therefore, this thesis describes the injection molding process, defines the properties of polymer materials, and presents a review of the literature on the causes of warpage. The computer simulation was performed in the Moldex3D software according to the central composite design plan, based on which the optimal values of the process parameters were obtained to obtain the minimum of the warpage and acceptable surface flatness.
