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.

Automation in High-Pressure Die Casting

2008
Abstract High-pressure die casting is a fast method for net shape manufacturing of parts from nonferrous alloys. This article reviews the automation technologies for the different stages or steps of the process. The steps include liquid metal pouring, injection, solidification, die open, part extraction, die lubrication, insert loading ...

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.

Detection of cast residue on high pressure die casting die surface

2006
This thesis aims to develop a temperature feedback system that could provide the basis for automated detection of anomalies on the die surface (e.g., soldering) or for control systems that could improve product quality. A key factor in the provision of temperature feedback was the application of temperature probes positioned within the casting die ...

A heuristic approach to meet geometric tolerance in High Pressure Die Casting

Simulation Modelling Practice and Theory, 2012
Abstract In High Pressure Die Casting (HPDC), geometrical distortions usually happen during the cooling phase, due to the reduced cooling time and the high thermal gradient inside the product itself. This phenomenon affects most the thin walled products.

An Evaluation of Quality Parameters for High Pressure Die Castings

International Journal of Metalcasting, 2011
Several techniques for examining casting “quality” as it relates to high pressure diecast alloy A380 have been evaluated in the as-cast condition. The roles of three simple parameters were considered: a) metal velocity at the gate, b) the effect of increased Cu or Zn content, and c) the effect of rotary degassing on a recycled melt.

ATM: A Greener Variant of High Pressure Die Casting

Materials Science Forum, 2009
ATM high pressure die casting technology (ATM) is a variant of the traditional high pressure die casting (HPDC) process and is distinguishable by its characteristic lean runners that increase process yields. Reduced raw material consumption helps ATM leave a smaller footprint on the environment by lowering greenhouse gas (GHG) emissions during primary ...

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
