Tribological wear mechanisms of molds for high pressure die casting

Abstract

The goal of this article is to analyze and define mold wear in relation to: mold material, casting alloy and casting parameters. These are the main elements for design of the experimental laboratory for die casting equipment. Additionally, preliminary tests have been undertaken to ensure there is no adhesion between the mold material sample and molten aluminum during the simulation. Factors that were tested were: geometrical shape of the sample, sample preheating temperature, surface roughness and lubrication.
