Even though cold chamber die casting is the most suitable method for casting Al-Si based alloys, they tend to react with oxygen atmosphere on holder crucible. Reacting with oxygen causes formation of oxide film layer and this layer can break easily while the melt is being picked up from crucible and it triggers the initiation of bifilms during solidifying. In this work, the comparison of the metal quality of molten aluminum alloy that obtained from the crucible and the solid part that obtained from the same melt after casting will be investigated. Cast samples will be produced for before and after degassing processes. X-Ray radiography will be used for viewing porosities. Metal quality will be defined and bifilm index will be measured by Reduced Pressure Test (RPT). As a result, the effect of cold chamber die casting method on the metal quality will be revealed.
