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

Vacuum High-Pressure Die Casting

2008
Abstract Vacuum high-pressure die casting uses a vacuum pump to evacuate the air and gases from the die casting die cavity and metal delivery system before and during the injection of molten metal. This article describes the conventional die casting, vacuum die casting, and high-pressure die casting processes.

Rapid tooling of high-pressure die casting moulds

ATZ worldwide, 2001
If car makers are to remain competitive, they must be able to market higher quality products in ever shorter periods at increasingly lower costs. The resulting demands that car manufacturers make of their components can be met best of all by products that are manufactured using high-pressure die casting. It is important, however, that prototypes of the

High pressure die casting mould repair technologies

2017
This paper presents the most commonly used technologies for repairing high pressure die cast moulds. This production technology successfully solves most problems of the conventional casting technologies like: casting porosity, high surface roughness, long casting production times, inability to produce thin cross-sections and low dimensional accuracy ...

Modularization methodology for high pressure die casting dies

The International Journal of Advanced Manufacturing Technology, 2014
Focusing on a low price segment is usually not an option for production companies in high-wage countries. In order to stay competitive, companies have to match individual products with prices close to those of mass products. A proven instrument in reducing costs in manufacturing processes is modularization.

High pressure die casting of non-ferrous alloys

Materials Science and Technology, 1988
AbstractHigh pressure die casting is a ‘traditional’ process which, over the last 15 years, has completely modernised its technology. In this paper, it is described how basic research has led to fundamental changes in die design techniques which, coupled with improved process control and alloy development, have extended the scope of the process and ...
