The invention relates to a press device for the energy-efficient curing of a sandwich component (6) for aircraft, said component having an open core structure (7) that can be subjected to sufficient mechanical stress and cove r layers (8, 9) on one or both sides. According to the invention, the sandwich component (6) is clamped between a pressure die (1), a counter-bearing (2) a nd the lateral walls (3, 4) of the press device, forming an essentially closed interior (5) and at least one cover layer (8, 9) and/or the core structure ( 7) is formed using a curable duroplastic plastic material. Hot air (16) is guid ed by a transport unit (20) through the core structure (7) of the sandwich component (6) in a closed or preferably open hot air circuit to guarantee th e energy-efficient curing of the sandwich component from within. The temperatu re of the hot air (16) is controlled by a heating unit (22). If the hot air circuit is open, heat is recovered by means of a heat exchanger (28). Said press device enables defined curing parameters to be set within the core structure (7) of the sandwich component (6), in particular a curing pressure PCuring and a curing temperature TCuring in conjunction with the resin syste ms that are used in the production of the sandwich component (6).
