Analiza injekcijskega brizganja akrilonitril-butadien-stirena (ABS) v orodje s 3D tiskanim polimernim vložkom

Za preoblikovanje termoplastičnih mas potrebujemo orodje, v katerega pod tlakom brizgamo raztaljeno plastično maso. Zaradi visoke cene izdelave takšno orodje uporabljamo za masovno izdelavo tridimenzionalnih izdelkov, ki so zapletenih geometrijskih oblik. Izdelava takega orodja je tehnološko zahtevna, draga in zahteva dolgotrajen tehnološki proces. Zato se pri izdelavi prototipnih in malih serijskih brizganih izdelkov uveljavljajo 3D-tiskana orodja. Namen diplomske naloge je bila izdelava izdelka v prototipnem orodju. Potrebno je bilo ovrednotiti dejanske odstopke geometrije izdelka od predpisanih. Za brizganje zahtevane geometrije orodja smo uporabljali material ABS. Z izbiro pravilnih parametrov brizganja polimera smo ugotovili, da je proces izdelave takšnega izdelka zelo kompleksen. Glede na omejitve prototipnega orodja smo v končni fazi ugotovili geometrijske odstopke zahtevanega izdelka.

• Title: Analysis of the injection molding of acrylonitrile-butadiene-styrene (ABS) into the mould with 3D printed polymer insert

Abstract

Injection moulding is a manufacturing process for the production of parts by injection of an under pressured molten material into a mould. Due to the high cost of production, such a tool is used for the mass production of three-dimensional products, which are geometrically complex. The production of this tool is quite challenging, since it's expensive and requires a long-lasting technological process. For this reasons, most companies, for the production of prototype and serial injected products, have recently started to use 3D printed tools. The purpose of the thesis was to produce a product in a prototype tool. It was necessary to evaluate the differences of the product from the prescribed ones. In order to make the product we have injected into the mould the ABS material. By selecting the correct parameters for the injection of the molten material, we came to the conclusion that the process of making such a product in such a mould is very complex. In the final phase we commented the geometric deviation of the required product.
