Abstract
A method for adhesively bonding a covering to a support using a dry heat-sensitive adhesive to produce an assembly for an automotive interior. The method positions the layers to form an assembly of material layers in tooling that concentrates microwave radiation energy conversion to the adhesive layer above its melting temperature. The method for fabricating an assembly in accordance with the subject invention, particularly when the tooling is transparent to the radiation, controls the radiation reflection, which is generated at a frequency exceeding 30 GHz.
