Abstract
A method for the production of molded bodies comprising foam particles is proposed in which the foam particles are shaped and welded together using microwave energy. The foam particles are accommodated in a foil-like bag and the bag is manually shaped or shaped through the use of a shaped mold with simultaneous change of the shape of the foam particles, and evacuated into a dense package. Microwave energy is subsequently used to melt together at least the surfaces of the foam particles. The method in accordance with the invention is particularly well suited as an economical manufacturing technique for packaging, in particular specialized packaging for models, small production runs, prototypes and the like.
