Technological Aspects of Returnable Material Introducing within Die Casting Technology

Summary/Abstract: Recent survey in manufacturing of aluminium alloy casts, which are now deeply implemented into fast developing car, shipbuilding and aviation industries, is focused on increasing of utility and quantitative properties of a cast to gain its high levels of mechanical properties at reasonable costs. One way how to minimize manufacturing costs is using returnable material at the manufacturing process. The submitted paper deals with an analysis of influence of the percentage proportion of returnable material in a batch on technological manufacturing of aluminium alloy casts. In the experimental part are described the performed experiments aimed to analyse returnable material impact to cast quality represented by monitored mechanical property – a permanent „s“ deformation.
