1. A method for producing a sandwich component, comprising:
compressing an outer shell and an inner shell together with foam particles lying between them in a cavity, which cavity is formed by two mold halves of a compression mold, under pressure and at elevated temperature to provide the sandwich component, wherein
at least one mold half is heated to a higher maximum temperature in a first temperature-control zone than in a second temperature-control zone.
