A process for the manufacturing of thermoplastic products with a high creep strain resistance. The products are free from reinforcing additives. The process includes at least vacuum forming and/or blow moulding of a thermoplastic material such as a polyolefine. A number of product parts are manufactured from a number of preferably tube- or sheet-shaped work pieces. The work pieces are heated so that the thermoplastic material softens whereby they are given the desired shape by means of a mould and the influence of vacuum and/or pressure. The product parts produced are allowed to cool and post-shrink and are hereafter joined to a unit.

L'invention concerne un procédé de fabrication de produits thermoplastiques qui présentent une forte résistance à la déformation due au fluage, et sont exempts d'additifs de renforcement. Le procédé consiste à former sous vide et/ou à mouler par soufflage un matériau thermoplastique tel qu'une polyoléfine. Un certain nombre d'éléments du produit sont fabriqués, de préférence, à partir d'un certain nombre de pièces à travailler en tube ou en feuille. On chauffe les pièces à travailler de manière ramollir le matériau thermoplastique, puis on utilise un moule pour leur conférer la forme désirée au moyen d'un procédé sous vide et/ou par pression. On procède au refroidissement et au post-retrait des éléments du produit ainsi obtenus, puis on les assemble en une unité.
