METHOD FOR THE PRODUCTION OF THERMOPLASTIC HOLLOW ARTICLES

摘要

The invention relates to a method for producing thermoplastic hollow articles, comprising: producing web-shaped or plate-shaped parisons (1) from melted plastic in such a way that the parisons (1) receive a specific wall thickness profile; cooling the parisons (1) to obtain dimensionally stable semifinished products (11) that still have the same wall thickness profile; heating the semifinished products (11) and shaping the heated semifinished products (11) into parts of a hollow article; and welding the semifinished products (11) together to obtain a substantially closed hollow article.
