摘要： an apparatus for producing bodies of polymeric material having an outer shell and a core of foamed material is disclosed. The apparatus includes an extruder and accumulation chamber for extruding a tubular element, i.e., a parison, and a second extruder and accumulation chamber for injecting a foamable polymeric material for forming the core of the body inside the parison. The injection occurs inside the walls of a mold, which causes the tubular parison to undergo swelling due to the expansion of the foamable material until the parison conforms to the shape of the mold.

摘要： A process for preparing structural, heat-insulating shaped bodies which does not necessarily require the use of a foamed heat-insulating material obtained by the use of blowing agents belonging to the class of chlorofluorocarbons. The process includes inserting a heat-insulating pre-molded core inside a tubular element made from an extruded thermoplastic polymer; placing the extruded tubular element containing the pre-molded core into a blow-molding mold; and molding the tubular element into a shell by blow-molding. By subsequent mold closure, the shell adheres to the pre-molded core. An alternative process is disclosed for adhering the tubular element and pre-formed core by closing the mold and drawing a vacuum within the tubular element.
