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.

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.
A compression mold for producing a sandwich component, comprising:
- two mold halves which are movable relative to one another and which, in a closed state, enclose a cavity in a shape of a component to be produced;
- two temperature-control apparatuses by which, in at least one mold half, a first temperature-control zone and a second temperature-control zone are temperature-controllable independently of one another;
- and
- a control device which is in an operative connection with the two temperature-control apparatuses and is configured to heat the first temperature-control zone to a higher temperature than the second temperature-control zone.
