Abstract

The invention relates to a process for producing a blow moulded article by the process of extrusion blow moulding. A split blow mould (4) is used for this. The parison is introduced as a tube (31) in the thermoplastic material state into the opened blow mould (4). After the closing of the blow mould halves (41, 42), the parison is brought into contact with the inner contours of the blow mould (4) by a defined blowing pressure and, after the stabilisation, is removed from the reopened blow mould (4) as a finished moulded article (3). The invention consists in the hollow inner space of the blow moulded article being filled with foam (71) between the end of the blowing process and the opening of the blow mould with the utilisation of the process heat remaining in the wall of the moulded article. <IMAGE>
