Abstract

Thermoplastic products, free from reinforcing additives but having high creep strain resistance, are produced by vacuum forming and/or blow moulding a thermoplastic such as polyethylene, polypropylene, or polybutene. A number of product parts are manufactured from preferably tube or sheet shaped work pieces which are heated to soften the thermoplastic and then shaped using a mould under the influence of vacuum and/or pressure. The product parts are allowed to cool and post-shrink and are joined to form a unit.
