Method of manufacturing an arrangement for the transport of media and arrangement

A method for manufacturing an arrangement for the transport of media, comprising a base body formed as a blow-molded part and at least one functional element, comprising:

• Providing and arranging a preform consisting of polymeric material and at least one functional element in a blow mold;
• Forming the base body from the preform, wherein the preform bears against the functional element during forming, wherein the blow mold has a first mold element and a second mold element,
• wherein the base body is formed from the preform between the first mold element and the second mold element,
• wherein the first mold element and the second mold element bear against the functional element in such a way that excess material produced from the preform in the area of the functional element during blow molding can be removed, and
• wherein the first mold element and the second mold element are configured to bear linearly against the functional element with elastic pretension during blow molding such that no deformation, including no partially plasticized or melted area by introduction of heat, is introduced into the functional element.
