Abstract

Aluminum-Silicon alloys are the most extensively used Al foundry alloys and are widely used in high-pressure die casting (HPDC) of automotive components. Several process parameters need to he controlled during HPDC in order to obtain sound and reliable castings. Among the different process variables, the determination and control of the injection parameters, such as the gate velocity and intensification pressure (IP), remain a key requirement throughout the HPDC process. This work critically reviews the effects of the injection parameters on the porosity and tensile properties of the die castings. The results of the literature review are summarized and optimal values for the gate velocity and IP are suggested.
