Core Viability Simulation for Salt Core Technology in High-Pressure Die Casting

University of Erlangen-Nuremberg, Erlangen, GermanyB. Fuchs & C. Körner Casting Technology Development, AUDI AG, Ingolstadt, GermanyB. Fuchs & H. Eibisch Corresponding author Correspondence to B. Fuchs. Abstract In high-pressure die casting (HPDC) undercuts can only be fabricated by using complex high-maintenance sliders. Until now, this technology has not been used for large-scale and cost-sensitive serial applications. Sand cores from

DEVELOPMENT OF WATER-BASED CORE TECHNOLOGY FOR LIGHT ALLOYS

ABSTRACT This thesis describes, in a manufacturing context, the development of new waterbased core technology for light alloys. Cores used for steel casting are made from fused silica and are removed using hot sodium hydroxide under refluxing (pressurising hot acids). However, aluminium and other light alloys are attacked by sodium hydroxide. Currently there is no
