Feeding Mechanisms in High-Pressure Die Castings

Metallurgical and Materials Transactions A, 2010
This work focuses on understanding the feeding behavior during high-pressure die casting (HPDC). The effects of intensification pressure (IP) and gate thickness on the transport of material through the gate during the latter stages of HPDC were investigated using an Al-Si3MgMn alloy.

Advancements in High Pressure Die Casting of Magnesium

Advanced Engineering Materials, 2007
The high pressure die casting (HPDC) process is characterized by rapid die filling and a subsequent rapid cooling of the molten metal. These characteristics are favourable for magnesium die casting alloys. Due to the high cooling rate the microstructure formed reveals a fine dendrite and grain structure, which in turn leads to substantial hardening and

Heat Treatment of High-Pressure Die Castings

Metallurgical and Materials Transactions A, 2007
High-pressure die-cast Al alloys cannot normally be heated at high temperatures due to the presence of pores containing entrapped gases, which lead to the formation of surface blisters. It has been found that blistering can be avoided by using considerably shorter solution-treatment times and lower temperatures.

Gas content in high pressure die castings

Journal of Materials Processing Technology, 2011
This paper presents the results of a quantitative study of the gas level in various types of castings from the high pressure die casting (HPDC) process using a vacuum fusion method. It was found that the major part of the gas was from the air entrapment during cavity filling.

Simulation of High Pressure Die Casting Solidification

Materials Science Forum, 2006
By the help of simulation software it is possible to follow and predict the high pressure die casting process. In the Department of Foundry Engineering at the University of Miskolc, Hungary we use both Finite Element- and Finite Difference programs for simulation.

Microsegregation in High Pressure Die Cast AM70

2016
High pressure die casting (HPDC) is the predominant manufacturing method for magnesium alloy automotive components. Cooling rates during HPDC may reach 300°C/s; however, the phase transformation kinetics in this regime are poorly understood. In this study, a description of microsegregation in HPDC AM70 is obtained by electron probe micro-analysis (EPMA)

Plating of Magnesium High Pressure Die Castings

Transactions of the IMF, 1980
The use of magnesium alloys, with their exceptional low density, good formability, in particular by pressure die casting, can lead to considerable weight savings in structural parts.
