A heuristic approach to meet geometric tolerance in High Pressure Die Casting
Simulation Modelling Practice and Theory, 2012Abstract 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.

Vacuum High-Pressure Die Casting
2008Abstract 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
2006This 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 ...

An Evaluation of Quality Parameters for High Pressure Die Castings
International Journal of Metalcasting, 2011Several 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, 2009ATM 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 ...
