Abstract
A method and compression mold are provided for producing a sandwich component, in which an outer shell and an inner shell are compressed, together with foam particles in a cavity between the shells, which cavity is formed by two mold halves of a mold, under pressure and at an increased temperature to form the sandwich component. At least one mold half is heated in a first temperature-control zone to a higher maximum temperature than in a second temperature-control zone.
