Abstract
A new approach for lost cores for light-metal casting was developed based on the substitution of sand by hollow additions with specific compression strength. The suitability of phosphate, gypsum and cement binders for such cores was tested. Test parameters were the molding behavior of the cores, their bending strength, surface quality and easiness of demolding. The core behavior during the casting process was evaluated using aluminum casting experiments performed in permanent molds. Feasibility could be shown for phosphate and cement binders, the latter having a higher bending strength.
