ABSTRACT:
Molding of expanded plastic material such as dielectric material by microwave radiation is effected in a mold in which the part of the mold which contacts the material to be molded is of a material having high dielectric losses and capable of absorbing microwave radiation. Such mold portion preferably comprises a resin containing a small amount of carbon black.
