Influence of die casting process parameters on castability and properties of thin walled aluminium housings

摘要

The objective of this study is to clarify effects of high pressure die casting process parameters for castability and mechanical properties. So the optimal die casting conditions for producing for thin walled Al component was conducted computational solidification simulation and actual die casting with three different venting systems, four straight, checker and full checker vent. Furthermore, the die casting process parameters, such as die controller temperature, high injection speed and die open time, were experimentally evaluated. The results of computational solidification simulation were found that the control of process parameters could lead to soundness of surface and no defect and improvement of mechanical properties. As increasing the high injection speed from 2.0 to 4.0 m s{sup}(-1) and die temperature, the castability was increased. The full checker venting system had best castability with good surface quality among the three cast specimens.
