Optimizacija procesa injekcijskega brizganja polimerov z metodo načrtovanja eksperimentov

Perko, Blaž (author), Kramar, Davorin (mentor)

Magistrska naloga zajema optimizacijo procesa injekcijskega brizganja polimerov izbranega izdelka iz poliamida VESTAMID L1930. Cilj optimizacije je bil določiti vpliv petih procesnih parametrov na dimenzijske lastnosti izdelka in skrajšanje časa cikla ob doseganju dimenzijskih toleranc. Predstavljene so teoretične osnove procesa injekcijskega brizganja polimerov, polimerih materialov in industrijskega eksperimentiranja. Dodaten poudarek je bil posvečen določitvi sposobnosti merilnega sistema. Določili smo sposobnost 3D-skenerja za merjenje karakteristik na izbranem izdelku. Optimizacija je bila izvedena po metodi načrtovanja eksperimentov z uporabo načrta s centralno zasnovo. Rezultate smo analizirali po metodi ANOVA. Določili smo optimalno nastavitev izbranih procesnih parametrov in ustreznost rezultatov preverili s potrditvenim eksperimentom.

• Title: Optimization of the polymer injection molding process using design of experiments

Abstract

In this Master´s thesis, we performed the optimization of injection molding process of a selected polyamide product. The aim of the optimization was to determine the effects of five processs parameters on the dimensional properties of the product and to shorten the cycle time while achieving dimensional tolerances. The theoretical foundations of the processs of injection molding of polymers, polymer materials and industrial experimentaion are presented. Additional emphasis is placed on determining the capability of the Measurement System. Optimization was performed using the Design of Experiments method. The results were analyzed using the ANOVA method. We determined the optimal settings of the selected process parameters and checked the adequacy of the results with an Confirmatory Experiment.
