Abstract

Namen diplomske naloge je bil, preizkusiti vplive hitrosti brizganja, naknadnega tlaka in časa vulkanizacije z vidika čim hitrejšega odpravljanja zastoja proizvodnje zaradi napak na izdelku. Želeli smo ugotoviti, kateri parameter med tremi vpliva na določeno karakteristiko izdelka in v kolikšni meri, ter glede na dobljene rezultate navesti priporočila za čim hitrejšo odpravo zastoja. Po pregledu tehnične dokumentacije smo izbrali nivoje, na katerih smo opravili preizkuse in material etilen akrilna guma (AEM). Testi so bili opravljeni za vsak parameter na treh različnih nivojih. Ugotovili smo, da ima naknadni tlak večji vpliv na zalitost kosa kot hitrost brizganja, medtem ko ima čas vulkanizacije vpliv na trdoto izdelka.

Secondary title: Analysis of technological parameters of molding the ethylene-acrylic rubber
Secondary abstract: The purpose of the thesis was to test the effects of injection molding speed, holding pressure and curing time in terms of the fastest possible elimination of production downtime due to product defects. We wanted to find out which of the three parameters affects a certain products characteristic and to what extent. Based on the obtained results, we made recommendations for the elimination of congestion as soon as possible. After reviewing the technical documentation, we selected the levels at which we performed the tests and the material ethylene acrylic rubber (AEM). Tests were performed for each parameter at three different levels. We have found that the holding pressure has a greater effect on the pouring of the piece than the injection speed, while the curing time influences the hardness of the product.
