Novel cooling channel shapes in pressure die casting
International Journal for Numerical Methods in Engineering, 2001AbstractThe pressure die casting involves die designs incorporating cooling channels positioned to facilitate the controlled extraction of energy from a solidifying casting. It is now known that subcooled nucleate boiling can occur in cooling channels and this paper is concerned with novel cooling channel shapes that are optimized to promote and ...

An Experimental Study on the Cooling Effect of Die Casting Die Insert Cooling Devices
Heat Transfer, Volume 3, 2003Water is usually introduced into a die insert in die casting through a water line to reduce the temperature of the die insert and thus prevent its cracking. In many cases, a drilled waterline circuit is not possible due to confinement of the space. Bubblers or baffles then become typical water passage systems for die insert cooling. This paper presents

Relation between cooling rates and microstructures in gravity-die-cast AZ91D disks
Metallurgical and Materials Transactions B, 1999In-die temperature measurements during the casting of 3.5- and 11.7-mm-thick disks in metal dies at 100 °C, 200 °C, and 400 °C enables calculation of the heat flux from the casting to the die as a function of the casting parameters. Using the flux so determined, the temperature field in the plates could be calculated in agreement with measured values ...

Equation Model of the Cooling Process in High Pressure Die-Casting Technology
Advanced Materials Research, 2012In the die-casting technology there is very necessary to determine cooling process of castings in metallic mold especially in the case of castings with great weight to achieve quality surface and properties of the casting without any defects. To regulate cooling in the time course, it is desirable to develop equation of regulation system that ...

Evaluation of the cooling efficiency of pulse spray for high-pressure die casting processes
The International Journal of Advanced Manufacturing Technology, 2021This article examined the cooling efficiency of pulse spray under different pressures, duty cycles, and frequencies. The cooling curves of the surface temperature were measured, and the cooling efficiency was evaluated by the temperature drop and the recovery temperature at the die surface.

<div class="section abstract"><div class="htmlview paragraph">In most air-cooled engines, aluminum cylinder blocks are lined with cast iron, which enjoys a higher wear resistance than aluminum. Recently, rather than a turned periphery, an increasing number of cast iron liners have employed as-cast periphery with projections, so the liner ...
