Abstract

The invention relates to a method for producing an article from thermoplastic material in which a tube-shaped preform is introduced into a multi-part blow mold and is expanded and formed by applying differential pressure, wherein, before the forming of the preform, at least one insert is introduced into the preform by means of a first holding means and wherein, before the forming of the preform, the insert is taken over by at least one second holding means puncturing the wall of the preform, the second holding means being formed as a blowing pin and an expansion and re-forming of the preform taking place by applying pressure medium with the second holding means.
