Abstract

In the process of die casting the final quality of a cast is influenced by a great number of factors. The interpretation of the impact of the individual factors of die casting is based on the concept of the filling of a mould cavity. The issue of the filling of a die casting mould is complex due to the fact that the factors such as the cast structure and the mould thermal balance usually determine the real melt flow. High melt speeds in an intake port complicate the image of the flowing liquid because dispersive filling occurs at a specific speed. The main factors of die casting are: pressing speed, increase pressure, the melt temperature and the mould temperature. The presented paper deals with the experimental assessment of the impact of pressing speed on the mechanical properties and homogeneity of a die cast.
