MARIA KAPUSTOVA, JOZEF BILIK, MARTIN SAHUL, MARTIN RIDZON, CRISTINA STEFANA MIRON BORZAN EXPERIMENTAL RESEARCH REGARDING THE PLASTIC FLOW OF ALUMINIUM ALLOY EN AW-7075 IN CLOSED-DIE FORGING WITHOUT FLASH The paper describes an innovative method of production of non-ferrous drop forgings, a manufacturing method based on closed die forging without flash. From economic point of view, this method is very interesting for production, due to small quantity of lost material. The research was verified using DEFORM 3D software. In this way can be better understood the principles of forging process and can be analyzed the plastic flow of the material into the die cavity. This experiment was successfully performed at laboratory conditions and the results will be applied in practice.
