Abstract
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.
