Abstract

Improved method of molding plastic foam pieces provided with a sheath or wrap of plastic material that makes body with it, of the type in which the inner surface of the mold intended for molding the piece of foam is coated, with a liquid or pasty layer of non-foaming thermosetting plastic material, this layer is treated so that it is fixed or stabilized, and then, in the mold thus covered by the non-foaming film, the liquid destined to constitute the plastic foam body itself is poured, of luck that a foam body covered with a rigid or flexible film adhered to the underlying foam is obtained, characterized in that a mold is used which, at least in its part in contact with the skin, is of a compact material, that is to say, not spongy, of low thermal conductivity, that is, less than 5.10-3 cal/cm.s.º C, preferably between 10-4 and 5.10-4 cal/cm.s.º C, but of appreciable specific heat, related to the volume, that is to say, superior to 0,1 cal/cm.3.
