摘要

Process for casting molded parts comprises preparing a mold from cores made from molding sand, casting a metal melt in the mold, thermally insulating the mold before and/or after casting, and using process heat within the mold and insulation for the controlled treatment of the cast molded part and/or the molded material forming the core packet. Preferred Features: The process heat acts to burn the organic or inorganic binder in the molding sand. The molded part and/or the whole system is cooled in a controlled manner.
