Effect of Composition and Wall Thickness on Mechanical Properties of High Pressure Die Castings

Abstract:

In this paper we present two types of currently used vacuum systems on the HPDC and the preparation phase of an experimental tool. To investigate the properties of HPD castings we have designed a die geometry that complies with requirements of vacuum and non-vacuum systems. We used computer simulation to shape up the runner-and overflow-system. In the course of our work we examined specimens with differing thickness and alloys with different compositions to check the changes of mechanical properties and the effect of vacuum system.
